I recently acquired a 1987 civic wagon. I've decided to do a d16y8 with ex hydro transmission. I saw several companies making carb manifolds for the newer vtec motors, whether it be bike carbs or dcoe weber's. I went head and ordered hasports 84-87 civic d hydro mounts. To start off i started looking into the wiring differences of the oem harness. I wanted to start with the distributor. If any of you guys by chance know what all the wires from the factory coil on carb car are i can fill in the blanks. I know everything about the obd2a distributor.
Obd2a distributor d16y8
ckp position + light blue
ckp position - white
cyp position + yellow
cyp position - black
tdc sensor + green
tdc sensor - red
rpm signal : dark blue
ign output : black/yellow
stock wiring 87 carb car coil passenger fender
thin black/yellow- to distributor from bottom coil plug- funcition guess? ignition?
blue to distributor from bottom coil plug??function??
thin black grounds to housing
thick black/yellow to top coil plug- back to wire harness
blue to top coil plug back to wire harness
theres a few more wires in the area that have a junction relay and a green plug that goes back into the engine harness. these above wires are the main concern for function of the distributor. does anyone know thes wires functions or have a lead on a wiring diagram? I assume with the d16y8 distributor most will be deleted or not used as there isn't any use from modern position sensors.
I have tons of old single cam parts laying around is the largest reason for my choice, most junk yards around here wanted between 550-860 for a ew that hasnt run in years.
