ej2.2 wiring question

Featured Replies

Ok just did the EA82 to EJ22 swap in my 86 rx

Question is what's this white and red wire

go to?

it comes off of whatever this thing is in the photo

Won't need them. The green and yellow Are the only ones you'll need for a 22 swap.

The green and yellow wire now what does that go to?

and that thing in the photo is that something for the electric fans?

There are lots more wires that are needed for proper operation. At a minimum fuel pump output, starter signal, Batt, Ig switched, and ground for EJ ig. Relay

 

But the ones in that diode pack are as follows. 2 diodes in pack each with 2 wires, an "in" and an "out"

Diode 1

Yellow = Ig. Switched wire...should be tied into the EA, B/W wire at either the coil or the alt.

L.green = out through the diode to EJ ECU and Ig. Relay

Diode 2

Red/blue = fan relay trigger from ECU(-)

White/red = output trigger to fan relay(-)

"Yellow = Ig. Switched wire...should be tied into the EA, B/W wire at either the coil or the alt." Oh, so whats where it supposed to go.Ive always just jumpered the diode, because otherwise I don't have power at the ignition coil.Its good to know that there is a proper method to do it.
