Exclamation *1jzgte swap into mk3* wiring help.

I'm in the middle of a swap and am stuck at wiring.

I'm not sure how to remap, or make a jumper harness for the jza70 to ma70 body plugs.
I do have the pins from various locations on the web but everyone of them doesn't make sense.
If you can point me into the right direction please do.

(For some reason its not letting me search the forums. Hence new thread. I'm sorry if this question has been beaten to death.)

Well, I haven't chimed in because I've never done this swap, but I assume the issue you're running into is the dash harness (B1) plug. If I were to guess, your 1JZ harness probably has a B1 plug similar to that of a post 89 grey plug Supra. If that's the case you need to either a) swap out your dash harness and with one from a post 89 Supra or b) splice in the B1 plug from your 7MGE harness. In both cases I don't believe your N/A tachometer will work properly, due to the different ignition systems, so you will need to address that.

I posted a link a while back about plug differences, I'll pull it up and if its relevant I'll link it in this thread.

I was wrong, the M1 plug is the dash harness connector I was thinking of.

The first post of this thread should tell you most of what you need to know of the plug differences.
