1jz ecu questions.

[808steeze]

I was just wandering if anyone has ever found anything to add to this diagram http://web.archive.org/web/200512271.../92Supra6.html (Top left, ECU Pin outs)

Also what do I do with the ELS-Taillight on T5
and A/C control on T7
and STP- Stop Signal on T14


does anyone know what the 3 wires coming out of the A/C are for, the colors are blue, blue with a red line, and light green with a red line.

Is the blue wire for A/C control(T7), I opened up my harness and only the blue wire was connected.

Thanks for any help

Check out http://www.autoshop101.com/ under the tech articles. Im sure the others are there under a different header, but for the stock signal, the ecu uses it to modify fuel cut while under decel. And I bet the tail light input will have like a 50rpm effect on idle rpm or something like that.
