Can i somehow use my b1 obd2 wire harness and p75ecu for a b1 transplant into an ef dx hatch? I want to but i cant find the drivers side firewall pinout to make it work. I have a pr4 ecu also but i want to keep the p75 cuz its already chipped and tuned. Or would i be better off using the 90-93 TEG harness w/ resistor box and running my pr4? some ones gotta help cuz i wrecked my EG hatch and all this shit has to come out and go into my EF quick. Real quick. Like this weekend quick.
