Wiring factory ecu?????

[Fattony]

Ok ive spent the good part of the past weeks internet time searching and i still cant find anything relevant.

Want to put a 4ag into a ke30 corolla, what i would like to know is how to wire up the ecu. Basically get a copy of the wiring diagrams and wire one wire to fuse or what not, what i need to know is what wires do i pick of the 4a wiring loom to make the whole shooting gallery work.?

Given the KE30 is originally carby this project is pretty easy.

The main thing is to get all the wires from the ECU running to the sensors/other stuff they need to on the engine. This is fairly easy once you have a wiring diagram.

Other than this there is very little that needs to be connected between engine and car. The things that spring to mind are:
- Constant 12V (to ECU)
- Ignition 12V (to a number of things)
- Start signal 12V (to starter, ECU and circuit opening relay)
- Wire the alternator (4A will be internally regulated, so you can piss off the external reg)

PS, why 4A and not XR6T??

Also, if you haven't already, download and print out the relevant wiring diagram from club4ag tech.
