I am doing a H22a swap on my 94 Accord and auto to manual swap I am now doing the ECU part. I purchase a P13 ecu to go with th engine but I only have 3 available cables that will plug into it. Am I missing something and do I just disregard the the cables I unplugged from the tranny ecu. please some one get going in the right direction.

 

im sorry, i can't understand exactly what your problem is... is it that you have a H22 ECU but are missing cables? or is it that you have more cables than places to plug them in?
Either way, you will need to get a diagram for the ecu and find out what each cable is for and pair them w/ the correct orifice...

 

I have a P13 ecu that has 4 places to plug in cables. But 94 EX has only 3 available cable to plug into it. So there is 1 empty slot on the ecu.

 

Just plug in the main 3, the 4th one is most likely for an auto tranny.

 

My wire harness only has 3 cables the ecu has 4 receptacles and my car was originally an automatic I unplugged tcm.
