Ok guys, question for the ones running the ea81. I have an 85 Brat that I am putting in the Ej 2.2T. I have the ej engne in and am working on the wiring. I want to have the ea oil pressure gauge working.

I know I have to put in the ea sender into the ej. My question is for the ones that can just look at their cars would be easy. I have the stock ea wiring still in the Brat. I want to know which plug and which wire is the oil pressure gauge from the engine bay that I can just splice into.

Thx guys.

On mine I used the ej harness to run the signal into the cabin, then tapped into the back of the cluster. I left my setup completely reversible just in case for some reason I ever decided to go back to the ea81t.

Oil pressure switch wire for EA81 look for yellow with black trace. If it has factory connector was clear likely yellow opaque now insulator on a right angle female spade

Cool. I will do some checking.
