Let's say on the resistor box side of the plug you have 4 black wires running into the resistor box, and one red wire. Cut all of the wires off that run into the resistor box. Connect the one red wire to all of the 4 black wires. That will eliminate the resistor box.Originally Posted by D15B
The P05 is equally as shitty as a P07 ecu for that engine. It is a 1 wire o2 ecu that is for a 70 hp 8 valve non VTEC engine. Try to get a P28 if possible. Your engine will run terrible with that P05.
