i will be putting a 4agze into a ke70 soon.

Before I get into working on the mechanical part of it I thought id find out what I need to do for wiring.

 

what I need to know is what wires do I need to look for?

 

If I was to get the ecu pinouts then what do I need to change over?

I'm guessing power for the fuel pump relay?

power for the ignighter/coils?

what else?

 

there's a main harness for the engine that just plugs into the car harness on a mr2 right?

is there a way of just finding what things i need hooked up and tracking with a diagram?

 

 

any help would be greatly appreciated

Should only really need to tap a few things on the ECU harness into the main harness to get it going, 12v battery, 12v ignition switched, crank signal, earth etc..

 

Alternator wiring...

 

if you are lucky it may already have the circuit open relay for the fuel pump on the harness...
