6 Ways to Wire In Your ECU - Haltech Technically Speaking

[@adamm2716]

I'm not even in the market for a harness but I just enjoy hearing someone intelligently describe technology

[@802Garage]

Same.

[@emiliano29171316]

Haha yeah I do! They are friends of mine. :)

[@emiliano29171316]

802 Garage cool. I always see them in a bunch of others miata videos. And I always comment.

[@802Garage]

Yeah for sure. I try to be pretty active on small car channels and comment whenever I think I have something worth contributing, hahaha. Check out my channel if you like. I have a lot of projects coming including an MR2 and some SR20 stuff.

[@eTiMaGo]

Videos like this are why I really want to get a Haltech ECU. Researching now different options, and this level of information sharing is just awesome.

[@ironstyleperformance3936]

This just fully educated me with harnesses and wiring. Fully confident I can do my swap using your products with my own hands and mind 👍🏼

[@RubyGuidiez]

Thanks for this! The biggest concern I'm having considering my future turbo project for my 4g63 Mitsubishi Eclipse GS is wiring everything to the ECU. I really see this as an obstacle, but you made this a bit clearer. Will definately try to use a Haltech ECU. You're the man, Scott! Hoping to find some Haltech dealers here in Norway :)

[@802Garage]

Considering a similar project in the future. See my channel profile pic. :P Mine is a GSX though, but definitely leaning Haltech if I ever get an aftermarket ECU.

[@Alientraveler003]

Just listening to this guy will finish my build Thank you sir

[@djevohill]

I see you throwing everything in the trash to your left.. If you don't need the elite ecu with the premium loom, I'll take since you trashing it.. i'll pay shipping don't worry!!! :D Its always great to watch your videos and see how Haltech is evolving!!!

[@haltech]

+djevohill Nice try, sorry to disappoint you but it's a display box only, (empty inside)

[@propa22]

i really hope there Haltech do invent patch harness kit for ej20 2008 sti JDM or any newer car in the future... the cost of piggyback harness style are too expensive and not many tuner here in my city like to do it... but the elite 2500 are the best package of most ECU i have ever seen so far. Watcing the daisy bug really inspire me a lot.

[@williamtai7331]

Scott definitely keeps you interested in the topic that can otherwise be very boring.great job and awesome content much appreciated 👍🏼

[@dons1932]

Scott, this video is excellent HOWEVER. You guys need to do a video on wiring up a Smartwire PDM. This type of general loom wiring is pretty straight forward, but it's accessories and their fuses that really start stumping me.

any aussie car tuning video i watch is like god mode on information

[@bpturbo27]

Hello , I’m a big fan of your channel and love watching all your content on tuning and halltech knowledge, I am a die hard Mazda 323 familia/ laser tx3 fan . Being in Canada, we had in 1988 and 1989 , less than 2500 awd Mazda 323 gtx s and even less 323 Gt sedans with the same B6t engine but fwd. I have been extremely blessed to have owned quite a few of these amazing homologated road versions in my lifetime. Later on I fell even more in love with the 1.8L bp chassis turbo engines , I imported a 323 familia Gtr engine with harness and awd transmission that I couldn’t use in my front wheel drive set up , so I was sold on the Autronic Sm4 stand alone Ecu from Australia, the unit was very expensive and my local tuner was supposed to be an authorized dealer, he got the car running , at 15 lbs the car put down 237 hp on a real mustang dyno , big front mount intercooler and 2.5 inch exhaust, everything else , stock. I never really got to see the real power that engine could deliver because I’m sure my tuner wasn’t in his usual Subaru territory.

[@KristianGoesOn]

These videoes helps me alot during my engine build. Im just hoping Haltech had the best solution for my rb25 r33.

[@calebpeterson8322]

I've been wanting to swap a 2jzgte with a single turbo into my mk3 supra for a while. But I've always been worried about the wiring, that terminated harness sounds so great! I need one haha

[@keith_5584]

I do have to say, your documentation and resources are excellent. Your support of Mighty Car Mods is also an AMAZING tool to advertise your product, but unlike most PR campaigns it is honest and truth-worthy. I did have a question about the CANBUS integration for the Elite Series 750/1500/2500. With a second generation RX8 (CANBUS/DBW), the Cluster is CANBUS as a broker between the Primary PCM network, and secondary networks all CAN controlled. Would any of those Elite series models be able to communicate with that CANBASED cluster or would it be not possible to use that cluster and/or supporting systems. Cheers, Keith

[@haltech]

+Patrick We do not currently support the RX8’s factory CAN protocol - you will need to retain the factory ECU for body functions, and wire the Haltech in parallel for engine control.

[@keith_5584]

+haltechecu Thank you for the response, Do you have any videos on interfacing any CANBUS or like a overview of the Elite's Can features and both kinds of interfacing to OEM and Haltech? I am interested in the technology behind the interfacing beyond just my vehicle.

[@haltech]

+Patrick Not as yet but we might make one - if there is enough interest in the subject:)

[@billyjoe3309]

Love just listening to you explaining. Great job!

[@jpvill4th]

After seeing the Haltech unit that was used in the Mad Beetle build I was curious to see what I would need to get to install fuel injection and electronic ignition on my 1972 Super Beetle with the air-cooled engine. At some point I would like to have sequential fuel injection. My car never had an engine management system of any kind.

[@blitzeral8620]

Hi Tuning Fork, i'm in year 10 currently looking at future careers, i was just wondering what your job is technically classed as? Based on the types of things you do on mighty car mods, i think i would really enjoy a career similar. thanks, Lachie

[@jrgsxr33]

+Haltechecu Question...what's the best option for an Sprint RE ecu for an rx7 FC second gen? My friend started his project then hit a road Block... He basically took the stock ecu out and some of the harness. I've yet to dig into this for him to determine what's what. The Sprint RE ecu did come with a harness for the ecu but does not have the built in relays/fuses. I can always add one but wish it was all in one package. What we need would be links to best connector options to use for injectors, all sensors ect...can u help?

[@haltech]

Hi Fernando, The Sprint RE is an entry level ECU and thus very basic - you'll need the plugs for the engine side, and to wire up a fuse box, both of which you'll need to source from third party suppliers. Your other option is to upgrade to the Sport 1000 with a 13B terminated harness kit which includes both fuse box and engine connectors.

[@MrAcat1988]

great video thanks

[@nick66333]

great video m8

[@kyangsable]

Why would I pick the fused wires over the basic wires. what are the benefits? What application is ideal for the fuse universal wire vs an application for the basic universal wire.

[@haltech]

As it is explained in great detail in the video, the short harness is much shorter and is used to connect to your existing engine harness, the premium (long) wiring harness is used as a replacement of your factory engine harness - so basically when you're completely rewiring your engine.

[@tomstech4390]

[@x.grover.x9786]

Does the terminated harness also give Information to the vehicles stock dash?

[@sashazxtt]

regarding OBD2 - it seems there is a fundamental limitation with the Haltech ECUs. If Haltech devices are connected to both main and AUX connectors, there is no way to enable the OBD2 functionality.

[@haltech]

If your Haltech ECU can support 2 CAN networks, you would need to run all of your Haltech CAN devices through one port. This would free up your second network for OBD2. If you need more info you can contact our support team directly via www.haltech.com/contact-us

[@sashazxtt]

@@haltech Thanks. That's what I figured. As is, my Elite 2500 is wired to use Haltech devices on both main and AUX ports. The Nexus software is configured for both main and AUX for the Haltech CAN bus. Of course, when I enable the vehicle CAN bus on AUX port and Haltech just on the main, I get all sorts of DCTs (because the ECU doesn't get some sensors). Now, my question is how to wire things in such a manner that all Haltech devices are just on the main connectors. Isn't that's where the car's harness connects to? How to wire in additional things into it (like wideband, etc.). It's a Z32 with the PnP connector. I did contact support and we had a lot of back and forth via email, but my question above still remains. Thanks!

[@haltech]

+stevenminix There are three options for fitting a Haltech ECU to your RB: Fit a factory engine harness, and use the R32/R33 Pro Plugin ECU. Cut the Megasquirt connector off your existing wiring, and replace it with the Haltech connectors (34+26pin AMP) or Make your own custom engine harness, using the Haltech premium universal loom kit

[@stevenminix]

+haltechecu do you recomend the sport 2000 ecm for an rb26? I would like the best management for the motor with its big single turbo for a nice race when i feel like it and a real street driven car?

[@aussieweaboo1054]

So is this relevant only to replace the current ECU for tuning? or can it be used for an engine swap also? sorry for the silly question just trying to learn the terminology and ways things are done for engine swapping.

[@haltech]

Engine swaps is actually where a stand-alone aftermarket ECU would be most useful.

[@scadieee]

Is there going to be a terminated harness for a VQ35HR ?

[@haltech]

+Scadieee Due to having dual electronic throttles, the HR will require custom wiring, with either a Haltech installed in parallel with the factory ECU (using factory to control the factory throttles), or stand-alone in conjunction with a cable throttle conversion.
