3sge in a 91 n/a

i just got a 3sge from japan and am having trouble with the ecu. i got the wiring harness and ecu with it. 2 of the plugs from the wiring harness match to the new ecu, but the plug from my car dont match. i was wondering if anyone has done this swap and has any info for me. like where i could get th wiring for my car. it is the plug that is on the left side of the firewall from the car. i think it hooks up to the gauges or ignition. i also need to know if the collector pipe from a older ( 84-89 ) celica will work? will the cv axle from the 5sfe bolt to the 3sge. i am confused here?

For God's sake man, this forum is a waste of time compared to the wealth of www.mr2oc.com

There's like a whole forum dedicated to that crap.

Goodluck, friend.

i went there but they didn't have any posts there for some reason. on any of the topics.
