1G S90 TB 90 to 91+ tps an isc conversion

[9412tsi]

So im throwing my setup together and I ran into a little snag. The car is a 90 and im using an s90 tbody which as we all (now) know only has provisions for 91+ tps and isc. My question is simple, do I just buy a 91+ tps and isc with pig tails and call it a day? Im pretty good with wiring but have not looked into if there are any differences in the way the tps and isc work. still using my 90 ecu that's on its way back from ecm link...any help would be very much appreciated!!!

thanks, that is exactly the write up I was looking for but could not find! even better I just found a 91 tbody with both the isc and tps intact so all I need no is a tps pig tail.

Remember to swap the white and black wires if you make your own conversion harness. They have the 91 body harness connector too if you need it for plug and play. Its what I used.

No problem, can always snag a pigtail from a junkyard too, if you have a yard thats nearby. Lots of mitz vehicles used the tps connector some are 3 pin others are 4.

yes I actually found a tpd connector new online for like 11 bucks you cant beat that also I was able to plug my 91 isc into my 90 harness so all I gotta do now is swap the pins on that. thanks again guys.
