Ultima RS Build 02 - Ancillaries! - Brake lines, wiring harness, radiator, & luggage bins

In this video I really dive into the build and install the brake lines, wiring harness, radiator & intercooler heat exchanger, and side luggage bins. I also do a comparison of the simple Ultima chassis wiring harness and the huge LT5 engine harness.

My son and I are building an Evolution. We are on hold while we move to a new shop. We eliminated all fuses, relays, gauges, switches and 1/2 the loom and wired for an Aim PDM 32 with a 10” dash. We really enjoy watching your build. Great stuff. Thanks.

[@UltimateUltimaRS]

Wow... I didn't even know Aim offered something like that and I just read up all about it. That is awesome. Did you modify the existing wiring harness to work with the Aim kit, or did you start from scratch?

[@tomcoury7154]

@@UltimateUltimaRS I put the harness on a board as is. Wired it up to test LED's, a battery and verified all of the circuits. I then drew a wiring diagram, then de-loomed and rewired it all. I did it for fun and really enjoyed it. The bad news is the harness is ready to go but the project is on hold until we move this month. I saw the PDM 32 last November at the AIM booth at PRI. It was supposed to be released in February 2020. Due to Covid (they say), it is still hard to get and I don't have one. I have programmed it in their Beta software and purchased the harness connectors so it's ready to go.

I have never heard a Clecko called a skin pin before in my life. I have built Super Late Model Cars for 35-40 years and they have aluminum bodies you have to make from 0.040 thick 4'x8' or 4'x10' flat sheets of aluminum. I must have 150-200 Clecko's. Skin Pins is a whole new name for me. I wish I could show a picture of what a car looks like I build. If you want to look up a friend of mine Scott Bloomquist on KZbin and that's what a car looks like. Skin Pins ROFLOL

[@UltimateUltimaRS]

So now you have 150-200 skin pins! 😄 I've always heard them said interchangeably. If you Google 1/8 skin pins, you'll see all the results are Cleco fasteners. I looked up your friend and he seems to be quite the legend in that series of racing. His hauler is amazing!

[@jimmymcmahon5961]

Yea Scott is definitely one of a kind racer. He has all kinds of Championship on dirt. He averages about 1/2 million dollars in merchandise sales a year. He has several nicknames, Voodoo Child, Black Sunshine and Bloomer. He has 3/4 of the field he races against just by intimidation. He broke his right hip at Bike week in Daytona last March so this year he hasn't won as much as he usually does because his recovery was slow. At 56 you don't bounce back as quick. I really enjoy watching you put your Ultima RS together. A friend of mine has been debating on ordering one. We are going to watch your build and see if he wants to do it. I told him I will help as much as I can. I have a brain injury and I can't fabricate like I use to. My left side is real weak and I'm left handed so I'm learning how to use hand shears with my right. That's why I'm watching your videos 2 or 3 times to see how much fabrication is done. Keep the good work up. I will be watching. 👍

Thanks, Steve!

[@rob105motorsport]

Not a road trip vehicle? I have plans for my surfboard and suction mounts. You're making some stout progress, Gabe. It all looks neat too! You did make me rush and check my harness for labelling though. As for that LT engine harness, you might need some extra horsepower to carry it.

[@UltimateUltimaRS]

Yeah I forgot you're putting rock sliders on yours! If anyone could make a rear wheel drive crawler, it's you Rob. I'm looking forward to seeing photos of your Ultima with the suspension fully articulated so put it on the white board!

[@rob105motorsport]

@@UltimateUltimaRS I need rock sliders for a trip to the coffee shop with our road conditions! I might have to upgrade the whiteboard for the suspension drawings and get a Beatles haircut so I can emulate Engineering Explained.

[@DriveDriverDriven]

I was driving mine 4 hours each way loaded with gear for a track day weekend, it's a perfectly good road trip vehicle! As for the LT harness, if you're going with the stock ecu, you can probably de-loom the braided shielded cable for the throttle sender, I'm willing to bet layout is very similar to the LS7 harness. It has enough length to reach the pedal from the side pod and you can make the harness look a lot nicer in the process.

[@mikeleonard8031]

Rod 105, I noticed that you are using a ruler to mark the robot holes. Take some elastic band that they use for clothing.Mark increments of 10mm on it. So when you stretch it, it will give you equal amounts of holes. I hope you under because English is not my native language.

[@mikeleonard8031]

Damn iPhone keeps changing the words. The worst phone I ever had.

[@aflatbroke1]

Like the others enjoying the two builds of yours and Rob105. Still dreaming of building one myself If a family member hadn’t robbed me of £500k.😤. I only live 20 minutes from Ultima, and about 5 years ago arranged a test drive with Ted Marlow in the silver GTR 550hp. The shear speed, grip and braking was unbelievable. My M5 drive home felt very slow. Boy you are going to be amazed with that LT5 and1000hp. Great vids and nice fast build too.

[@UltimateUltimaRS]

Thank you! I'd love to go to the factory one day but I'll get my first ride in an Ultima as soon as I can! I'm glad you're enjoying the build.

Nice vid and terrific progress! Just as a note...don't forget to put some "Second Skin" beneath the luggage compartment right above where the coolant hose sits. Many Ultima owners complain that the hose turns that box into an oven.

[@UltimateUltimaRS]

Good call! I'll definitely do that. Thank you!

[@regfenster]

Some great work here. I imagine the temptation to smash through it to completion is overbearing? Also great to see an Ultima build in the states, these things are a rarity here in the UK, in the US they're going to be like hens teeth! Enjoying both yours and Rob105's builds. Takes me back to when I had a Caterham a few years ago.

[@UltimateUltimaRS]

The temptation is definitely huge to get it finished! The rarity is real as well! Our local Cars & Coffee (before Covid) was one of the largest in the world. I've seen Bugattis, Paganis, Koenigseggs, and multiple new Ford GTs all in the same weekend, but never an Ultima. It'll be cool to have one there when things get back to normal.

[@regfenster]

@@UltimateUltimaRS I look forward to your Cars and Coffee vids once we're past this Covid nightmare. You and your Ultima will be the focus of much attention. I think its going to blow people away when they understand that you've built it from a kit shipped from England. I'm going to sub as I'm enjoying these episodes so much.

[@stevedunford7632]

Before you fit the body side pods run a length of rigid plastic DIY cable duct under both the luggage pods. Later on you may find you need to run extra cables you had not planned so you may need these ducts. Ask me how i know. I've built 5 Ultima.

[@UltimateUltimaRS]

Good to know and thank you for the comment. I have been waiting until the absolute last minute to finalize them and will search for some of that cable duct to use!

Another video outta the park! Your attention to detail is amazing, I don't know if I could do something like that or not, I'm too ADHD for that level of detail, I would just zip tie everything. LOL!! The work you put into the rivets is crazy! What are they 1/2" apart? Great job! I can't wait for the day that you fire that engine up.

[@UltimateUltimaRS]

Thanks, Russ! You'll be there for the first start, no doubt! Those rivets are spaced 30mm everywhere.

@@UltimateUltimaRS I forgot, that's an English car, it has to be in metric....

[@crycheck3585]

It's surprising that Ultima doesn't use hard lines for its brake setup. What kind of harness wrap does your body harness have? It looks like silicone tape, which is what I'm planning to use for a custom harness on a v8 conversion project. Nice build series, it's refreshing to follow a build that is all content and doesn't throw in a bunch of silly hype to get clicks.

[@MrDanieljanes]

What made you decide to dry wrap the header wrap? I found if you soak it first it's a lot nicer to work with and not as dusty.

[@UltimateUltimaRS]

The instructions indicated wetting was not needed, though looking back, I probably would have just so it was easier to work with.

[@Mudbuttmoody]

Literally the only question I had as well. I think its easier to get a more snug and neat fit when it's wet. Less wrinkles and loose spots

[@Acrowat40]

Rapid progress - cheers for doing the videos, really interesting! What would you say you are spending time-wise per week/day on this? Does the video add a lot of time to the build?

[@UltimateUltimaRS]

Thank you! I would say probably 4 hours average per day. The videos make the progress look very fast, but there is SO much off camera- measuring, cutting, fitting, deciphering the instructions, looking for parts, etc. The videos don't add too much but I end up with a lot of clips that don't make it into the videos so going through them takes some time.

The heat wrap, are you not suppose to soak it in water before applyiing?

[@UltimateUltimaRS]

DEI states it isn't necessary with theirs, though typically yes, that's what I've seen as well.

[@liamhunter2403]

So what made you choose the Ultima RS over something more local (Florida company) like DDR Grullon GT8ss?

[@UltimateUltimaRS]

The number one reason was just the pure look of the car. Also Ultima has a very cool company history, numerous records, etc. They have a very good resale value as well.

[@seanmesaehable]

could you have used something like a holley harness? there a little cleaner that gm harness

[@UltimateUltimaRS]

At the time of the build, there wasn’t a company that offered an ECU/Harness for the LT5 that controlled both direct and port injection. I definitely would have gone that route if so.

[@galadrhim1]

Is it coincidence that you used all of the same music that the Goonzquad uses, or do you follow them?

No coincidence there. ;) They have a great channel and it's tough to find good non copyright music.

Skin pin/kleeco

[@corey640]

Please, please, pretty please, don't used that LT5 harness. Look into something like a PDM that eliminates all of the bullshit, the fuse box, etc and makes for the cleanest installation possible. Haltech makes one that has a TON of features you could use on this monster like TC and a ton of I/O for just about everything imaginable. I think it's called the R5000? Also, on that DEI wrap, you're supposed to overlap it half way for maximum effect. Letting it soak in some warm water also makes it much easier and for a much nicer finished product as well.

[@UltimateUltimaRS]

Corey I'm right there with you but I haven't been able to find a plug and play aftermarket ECU for the LT5. I just went on Haltech's website and it doesn't seem like they have anything for the Gen 5 LT engines at all. I know Holly JUST came out with support for some of them and I was excited for that until seeing the ONLY engine they don't support is the LT5. Motec is an option but the cost of an ECU plus custom harness PLUS custom tuning is a huge cost. All those extra components from GM are going to be in the side pod hidden, with just the wiring harness for the sensors wrapped around the engine. We'll see...

[@corey640]

@@UltimateUltimaRS I'd contact Haltech directly and see what they can do, but if they can't help with a plug and play, I think your best option regardless is actually one of the kits and just source the connectors or use the ones from your harness and make it up yourself. There's a pretty good chance you'll have to some modifications to it anyway for layout and different placement of things anyway. It's not hard at all. One of the universal Haltech PDMs come so all you have to do is route it how you want and then crimp on the pins for the connectors. Can't ask for much easier than that. Lol
