Hello,

I've bought myself a 4AGE 20V Blacktop engine with uncut wiring and ECU. Now i'm looking for a wiring diagram for my 7AFE, i know the 4AGE 20V diagram is here already, but where is it located. I've searched and searched the site over and over again but without luck.

Besides that, who can tell which cables all have to be linked to the old harness? Should i buy a harness extender?"

Thanks folks!

No one???

do you have the 7afe ecu? if so pop off the top and look at the pcb board toyota labels the wire ports on the board.

I also found this

Yes i do have the 7AFE ECU, but also found the pinout.

I was hoping someone here did the conversion or either could tell me which wires should be all connected. That would've save me loads of time

We offer a plug and play conversion for 20V harnesses. Shoot me an email and we can discuss your project! cam@tweakdperformance.com
