So this wed. I got a guy coming to pick up my totaled civic and i wanted to get my motor harness out just in case i decide to do an obd0 to obd1 conversion on my 87 hatch. I had a couple of questions. The motor and tranny are out as well as the ecm, i read a tech archive about taking one out but it didnt help. Now do i need to pull out the dash and disconect anything from the cluster gauge or just feed the ecm cord through the firewall and im good to go? I ask about having to go through the cluster because my light wires are wrapped in the wireswith the motor sensors and its common sense that they run to the cluster, or can i just cut em? I have zero experience with wiring. Please help?
