I am buying a MR2T rear clip... But need the ECU wiring harness redone.. What all does that include? Is it just a matter of lengthening the wires to reach everywhere that the wires need to reach to? Or is it something different?
Thanks guys! Yota --------------------  |

wires need to be changed and lengthened
and with an mr2 harness, its even more work to get it done. make sure you have a car to drive in the mean time. -------------------- 1994 Celica GT4 WRC Edition

You need to take the stock plugs from your old harness and put some on the new harness. I would try not lengthening the harness and drilling ur firewall instead, theres less risk of changing the voltage or a solder breaking and causing alot of trouble.

i agree with supersprint.
you will also have to rewire your fuse box, and add in a relay for the fuel pump. just think of it this way....your 3sgte was made in 90-93. a lot of things changed in the 6th generation celica...you fuse box is not the same, and your interrior, gauges,, etc are also not the same. so you need to rewire all of that. -------------------- 15PSI - 30MPG - Megasquirt Tuned
