ok let me get this straight... the plugs from my 1jz harness doesnt not fit my plugs on my car... so does that mean i have to cut and solder the wires together... because from the looks of things from the website http://1jz-gte.us... it shows how to connect the wires and the plugs do look different.. well to get in more detail im talkin about the IH1, IG1, and IH2 plugs... the dont match im thinking its because my 1jz harness is off of a soar car and im trying to use it on a supra... im i wrong or what??? im really stomped... i'll post pics later.... tomorrow when its day time so i'll be a better pic... i really need help... trying to get the car running... and i need yall's help... thanks

Easiest way is to look at the ECU plugs. Here are the pictures of the plugs. Just look at these and match the shape of the plugs and you'll have your answer.

First one is the JZA70 (Supra) pinouts

Second is the JZZ30 (Soarer) pinouts

oh, ok. It isn't going to be plug and play. You will have to cut and splice. I don't know how to wire the supra harness. Sorry. G/L

Some of the colors are different because of the year of the supra. Get ahold of bigaaron for some advice. He can probably point you in the right direction since he is the expert at the swaps.
