i know there are many write ups on mpfi swaps and stuff but i cant really find the info i need.
Currently putting a B18B1 in my 1989 EF sedan, stock motor is an OBD0 DPFI D15B2. I am putting in an OBD1 converted B18B1, already have distributor jumper, ecu jumper, running an OBD1 PO6 ecu. My question is about what the 8 wires on the ECU jumper subharness are used for. Injector power, 4-wire O2 sensor? P.S. I am adding a resistor box and running OBD0 injectors. Pics below, thanks.
Although i was looking for an answer specific to my subharness and the funtions of each wire, the video did help me figure out that i need to hook the o2 sensor wires to the subharness. I'll just have to figure out which of the wires to use. thanks for trying to help though, i appreciate it.
