wtf
 

I recently got an 86,5 with a90 7m jdm 35k replace idk wtf the douche did he says he installed the 90 harness. When the bat is hooked up the check eng. and some other idiot light are on even with key off. the temp gauge also pegs untell ign. is on . Eng. turns over but has no spark or injector pulse. the main relay gets hot after turning over the eng im not that familiar with toyota wiring systems or wtf could poss. be wrong with them i just dont know but i would like to figure it out please help
PS. if its some thing simple dont think im a douche i would like to get it running so i can decide if its worth making it my project to spend $$$ on

THANKS

pps im also completely forum illiterate bear with me

I'll bet the '90 wire harness is different than the '86.5 harness. An exorcist or an electrician that can read wiring diagrams will be required to fix this. Even if you can find an '86.5 harness, you'll need a diagram to insure it is hooked up right. Wiring harnesses in these advanced EFI cars are not to be screwed with, especially with clubbed hands. You need to services of a good auto electrician to fix it.

Ok So If I Get Anew 86.5 Harness Wich I Think I Found And A Pin Out Diagram Start From Scratch I Should Be Good So..... Does Any One Out There Got A Pin Out For A 86.5 And Or 90 That I Can Possably Get The Link To? Cause I Just Dont Have The $$$$ Right Now For A Tech

Is the ECM a '90 or the original 86.5? Plus, I've haven't seen a 'pin-out' diagram, but just the standard wiring diagram from the TSRM. This page, Mk3 Supra TSRM (Toyota Supra Repair Manual) Links/Downloads , has a wiring diagram for the '86-'88, and the complete '90 TSRM. Maybe you can compare the two, and get the wiring harness to connect properly.
