Looking into a swap for my 94 300 and the vendor for the engine mentioned a harness extension made for the GTE that prevents you from having to manually lengthen the JDM harness or replace it with a Tweakedperformance harness. Does anyone know about this or is the $1k dollar Tweaked harness really the easiest way to do it? I prefer a $300 extension if its out there.

 

Extending isnt the only requirement for the swap you also have to cut and solder the sc300 body plugs into the harness.

 

If you want to do it yourself follow this thread. Best info out there for our swap https://www.clublexus.com/forums/per...made-easy.html

 

Lolololol @ tweaked.

The harness you're talking about would be just a jumper harness, but like somebody else said, still need to extend the body plugs, possibly some minor repinning. That's for a soarer harness into sc. All others is a complete rework. Good luck

 

What about tweak'd is funny? I have seen a few people who did builds using their harness's. I will say that they are expensive but sometimes its worth the hassle to just buy one. Is there a problem with them? I also saw a few people on supraforums that use their harness's as well.
