How to KEEP your STOCK GAUGES for ANY CAR with an LS SWAP | Swap Wiring Isn’t Hard.

[@lsxmatt]

It’s really that simple and should apply pretty much any car being ls swapped. Just run the factory gauge senders from your old motor on the new one. Obviously all cars will have different ways the gauge wiring is ran, so isolate the wire’s going to each gauge in the cluster. From there just route them to the senders on the motor as well as the pcm output wires for tach and speed! Also here are few things to add plus some stuff I forgot: 1. That 150amp breaker coming off the battery is way to weak to crank this V8 and will constantly trip. I'll probably end up replacing it with another busbar. 2. For the steering column I am going to install an astro van bearing, just didn't get it in time for this video. 3. For the gauges, speedo cable guys will need a gps conversion box to run the mechanical speedometer. Link in the description. 4. After your speedo and tach is wired, the signal will need to be calibrated to read correctly. This can be done via Hptuners software or with the Dakota Digital SGI-100BT box linked in the description. 5. FYI on LS swaps, you can use the ICT Billet adapter linked in the description to screw the oil sender into the side of the oil pan/oil cooler port. You may also need to use some 1/8 npt adapters from the hardware store to clear some headers. Only Gen V LT engines have that port I used due to the vacuum pump, LS motors do not. 6. Lastly I didn't include links for the 3rd gen oil pressure and coolant temp senders because all cars were optioned differently. Just go over to Rockauto.com, enter your vehicle info and choose the correct STOCK 80's sender. Hope this video clears some stuff up regarding gauge wiring on these thirdgens! The Trans Am will return again shortly!

PSA: DO NOT BUY FROM PSI. I say this, with great disappointment as i had very high hopes for a nice harness from psi after seeing this video. Installed everything, and the car misfired horribly on the passenger cylinders. Chased the problem and chased the problem until there was only one possible problem left; the harness. Checked the harness plugs at the pcm, and sure enough, it was pinned incorrectly. Coils were pinned out of order. Re pinned the whole red connector and im now problem free. Contacted psi about the issue and they basically told me “sorry about your luck, kick rocks.” So yeah, f*** Psi. Horrible customer service and an over-priced, sub-par product. Unless you want to have to re-wire a new 800$ harness, go elsewhere.

[@tdkyt46]

You should draw up wiring diagrams on how they have the loom and just send it to people as a last fuck you psi

@@chevrolet355 yep. Lesson learned. I know how to cut down a factory one myself, just wanted the nicer fit and finish of an aftermarket harness. I personally like the BP automotive ones.

[@justinw523]

I’m LS swapping a 1988 Monte Carlo SS with a 1999 5.3 and a T56 transmission, I done my own simple wire harness with help from LT1swap and the KZbin channel ucandoit2. It’ll take some time and patience but hopefully I’ll be able to use all my original gauges I know the Tach and oil pressure will work since those wires are coming from my PCM, the Purple 10g starter wire and 16g Pink Key On wire I’m trying to figure out where to tie those wires into, some say tie the Pink Key On wire into the old pink wire that was on your distributor and just use the original starter wire or splice the purple wire to the original starter wire. I’m old school still learning the LS scene as I go LOL

[@taijito79]

Great information! I'm currently doing a 67' Camaro, I have yet to find a detailed LS swap on the first gen's. It's always, "This is what worked for me..." Maybe I'm not looking hard enough, but this video is saved for tips and tricks, thanks again!!

Man, that’s one clean freaking build. We’re going all out full drag racing for the 91 Camaro, but I’ll be using your ideas here and stuff for my late fathers 1972 Chevy C-20 we used to drag race but I plan on taking the motor and trans out and LS swapping it with modern amenities as well

Good to see this beast getting some love again. While the cluster is out, maybe it would be a good idea to hunt down a factory 8000rpm tacho for the cluster. Shouldn't be too hard to find one of those. If you leave the poor old 6000 rpm tacho in there it may succumb from getting pegged into oblivion otherwise. 😎

[@jessesnayberger5934]

So basically, there is going to be like 6 wires or so for gauges kept from that c100 and thats all? I lost my battery cables and some others during the engine pull of the 350 and sitting for 8 years, now you have me debating on a rear battery relocation haha but good video man, my trans am has the digital dash but same harness essentially just different pins in the back I think. But great motivation and help with the simplicity of the original harness.

[@sogood4u489]

Hey Matt I talked to you on third gen I'm in Minnesota I started with a 91 camaro it ended up rotten bought a great 87 trans am red with silver ground effects, you liked how I painted the 5.3 to look like a sbc. I also went pci on the harness/ecm. I used a bmr k-member it is solid, so much that before when I jacked one side of the car one side still touched the ground now when I jack one side the whole cars front end comes up together... I love that but fitting ac is impossible. Any subjections of a k member that will let me fit the ac, I junked the stock k member even thought I got the whole holly ls swap kit 🤕. To much money not enough experience.

[@enermaxstephens1051]

This is cool and all, it would be really cool to know how to use any newer gauge, in any older car. So for instance if I wanted a particular cool looking set of gauges out of a 2018 lincoln, to work fine in my 1991 Camaro. It would be real nice to know how to do that.

Great work bro!!! I am done with my LT swap just need a shifter now 🤦🏾‍♂️ and we can make a test drive…. FYI I bought the speed engineering headers and true dual exhaust system, it fits perfectly but not a big fan of the clamps they supplied with it. but when I take it to the exhaust shop because there’s a very short distance from the headers to connect, I’ll have him weld some spots to stiffen it up A LOT… Here’s something I’m trying to figure out, how are we going to get the manual mode for the 6l80 to work???? You know I had swap time do my harness and he told me I can’t have both BCM and transmission module because I did the 6th gen dash swap with the gauge cluster I went with the bcm. The manual shift isn’t a much but will be needed for any racing especially burn outs

I have been looking forward to this video, your engine bays are clean and uncluttered. My only concern is the drive by wire for the throttle. My wife's Avalanche has this system and compared to my Camaro tuned port its geriatric in response. Are the aftermarket systems more responsive or maybe something you can adjust. Great content as usual keep up the good work. On a side note the Tahiti brake upgrade did wonders for my wife's Avalanche thank you for the information.

[@chriswiseman5143]

Yes! It's nice to see the Trans Am again! I'm following in your footsteps by repainting the engine bay on my '83 Z28. I should be ready to spray it next week. When you masked off the fenders to paint your hood jambs, did you let the masking tape hang over the edge of the fender or did you line up the tape edge with the fender edge? I've watched the painting video 20 times and haven't been able to tell.

[@JustinMyers]

tape just prevents overspray....so, if you dont want anything painted, tape it up... if you are OCD and need to have the tape line up with the edge of the fender, then do so...just be mindful of over spray. TLDR; you are overthinking this

What would be the best cylinder head option or should I use the cylinder heads that are on my engine? Do I need to change the wiring harness in my car? Do I need to change the ECM?
