I doubt it, but I figured I would ask. Is the mk3 1JZ harness usable for a SC 1JZ swap? Just figured I'd ask, since I have one sitting here that I could start lengthening. I have a spare 2JZGE (5spd) harness to salvage some of the body connectors from if they are simmilar to the mkiv supra vs the mk3.

Worst case, I'll unload it to a mk3 guy and buy a soarer harness :lol:

I dont think its usable... it uses all different chassis harness connectors... i mean you COULD use it but you'd be cutting all the harness connectors off and soldering them directly into your car... which would take a lifetime...

I'd just unload it to a MK3 guy and get a Soarer harness (who knows, maybe one of them needs a JZA70 harness and has the JZZ30 one himself)

 

But aren't both the engine side and ECU side connectors different than a Soarer? I almost bought a 1JZ with a bit lower miles, but had to go with mine w/ 60k miles because of the connectors...

 

I'm not understanding you I dont think

I do know that the Supra has different auxillary boxes (like for fuses and such) and a few other things...
but I think on the SC you wouldnt be swapping those anyhow?

The injectors, map sensor, various other sensors, etc all have the same plugs as far as I know (the important part)
