like it says fellas, im having trouble hooking this up and i dont wanna have to take it somewhere and spend 100 bucks on switching over 3 or 4 wires. apexi is hooked up already, vtec/ and rpm work, but i have a cel code 21, throttle and pressure on apexi controller arent working, color of wires arent the same as directed on the apexi manual for example n the throttle snesor, their are three wires correct? which are the ones im suppose to cut and splice into for input and output? ive searched for this and havent really found a direct answer with a h22 civic .
thanks in advance fellas!

 

BTW: i have a 92 civic si w/ jdm h22 p13 ecu. i believe its a obd1 correct.

 

ANYONE? the diagrams that comes in the manual, will it be the same if its a jdm p13 or is it just for usdm ecu's?
