Anyone here know how to convert these wires? 89Cressida Auto 87-88 Supra Turbo auto. Maybe some of our Supra guys DownUnder might know this.

I know what will work on a GTE swap.........
Use the damn GTE ECU & harness !!

Does the Cressida have any sort of boost timing retard programed into it ?
No Way !
Does the Cressida have 2 knock sensor imputs, like what Toyota thought the GTE needed ?
Nada !

I see a blown 7M in your future.
Then you can join all the 7M haters, and put in a one jay zee.
Try running that off a 7MGE ecu, and you will blow that up also.

There's nothing wrong with an 87-89 7MGTE. 1 is getting ready to post in @ # 6 once I post the dyno chart and maybe higher when regular E85 in the summer comes into play for CHI2K12, instead of the E70 that it was probably running on in December.

And talk to tweaked performance he does whole harness conversions, jumper harnesses. Also a mod on SM and knows the chassis and engines wiring probably by heart.
