EJ swap wiring diagram

[Numbchux]

with all the questions about how to wire the relays on an EJ swapped car, I thought I'd draw up a little diagram of how I have it wired.

 

 

obviously, the arrow marked (to rest of Ej harness) will go throughout the harness and give power to anything that needs power (coil, all ECU plugs, injectors, igniter, etc.)

 

the 2 leads on the ignition switch that just go to a "+" sign get power via the EA harness.

 

and the wire to the starter relay should remain factory EA.

 

now, for security, you could wire a rocker switch (that always gets power) instead of the ignition switch to power the ignition relay (what I've done). this allows 3 things.

1. the car cannot start without flipping the switch (hidden kill switch)

2. you still need the key to start it

3. you can leave the car running to warm up with the ignition off (all accessories off, headlights, etc. and steering column still locked).

 

 

I will be adding this to my write-up.

that's EXTREMELY timely for me . Good diagram!

Good job Numbchux. Can I put that on my site?

 

To some this just looks like how it should, to others it's a master piece.

You do have to have a slight concept of electricity when doing a conversion like this.

you most certainly can. but I've already added it to the write-up. which, if I get my sorry butt in gear, I should be able to have up on our school's server by the beginning of next week.
