hey guys, im running a USDM 2J ecu on my car with a MAP ECU. a buddy of mine made the adapter harness for me, and it works cuz i drove the car today after fixing a timing issue. my question is this, what wire do i need to connect or what to get the fuel pump to work. Its working right now by bypassing the circuit open relay to make it come on with the key turned on. that relay got a little too hot today and the pumps shut off. so i need to know what to connect and where in order to have the pumps working normally. my friend wasnt too sure about that wiring because of the fuel pump ecu that the mkiv has.

thanks for any help guys

You wont be able to have the stock ecu control the fuel pump unless you get the fuel pump ecu. The only way is the have it come on with the key or get something aftermarket to control it.
