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.
