Hi there i was installing my new bee*r rev limiter/ launch control unit and the instructions come completely in japanese text. i know what wire is what off of the bee*r unit but i'm having an issue with my rpm signal and ignition in the car.

i think we used the wrong wire from the car as the instructions aren't very good.

i am looking for a obd0 pr3 pin out diagram. I need to know what wire is the rpm and ignition signal.

i have a b16a in a 91 hatch

any help is appreciated, thanks!

 

I believe I have used b15/b17 (white) wires as my ignition output signal but it's not working properly.

I'm interrupting the b15 signal with the rev limiter and i have b17 cut and isolated off. i'm going to switch it, and interrupt b17 and leave b15 isolated instead.

 

i had my wiring right, just had a dirty power source.

problem fixed! thanks
