Question Wire harness for track car

Anyone know who makes wiring harness for track cars? I am building an LS1 powered GT car, and only need CPU, tach, oil temp, oil pressure, and water temp.
Thanks!!

A Painless harness is in my CMC road racing car ...

Very lightweight, easy to install, plenty of "slack", primo connectors ...

If you want you can just cut the stuff off you dont need. That and HPtuners to delete any codes should work well.

What additional connections?

My harness came with the bare minimum connections to make it run. There were no trans connections, lights, HVAC, etc.

I had to run my own brake lights, fuel pump and level, clutch interlock, and guage wiring.

You may also want to check with Speartech (sponsor). They make/modify harnesses for LS1 conversions/hybrids. They may have something that will work for your application.

Also, if you want to modify it yourself, there is a ton of info. in the conversion/hybrid forum.

Yes, we've made several harnesses for race cars. We custom build to the length YOU want for convenient placement of the PCM. Since our harnesses are custom made it will only include the items you need, as well as containing the proper connectors for the specific MAF sensor, throttle body (ETC or cable), etc., that you are using.

Let me know if I can provide any more info.

Thumbs up Harness information

Many thanks guys for all the helpful information!!! Now I'll start to digest all this and take it from there. This is really a great site as this is my first use of an LS1 in a SCCA GT car with all the fuel injection/computer issues.
