Im so lost when it comes to the coil wiring. I just swapped out my harness for an 87 b2000 harness for my 89 b2200 motor. I have the wires coming off the dizzy which are blue wires with 2 single blade connectors on them and they are tied together and I have single black wire coming off the little black box on the dizzy. I then have a large single black wire with a white stripe and some solid yellow wires with the same single blade connectors and they are tied together coming out of the harness. I have around 6 wires and I dont know where they go! PLEASE HELP!!!
if this makes any difference, the body is an 87 b2600, the motor is an 89 b2200 and the wiring harness is an 87 b2000. Its all I have to work with here so be gentle!
Ok if i remember right the black with white is the main power to the coil (pos side) the black box on the dist to the pos side also blue to pos. The yellow is the neg side. There are extra plugs on the harness on my truck they didnt plug to anything on the yellow and blue i think they were for electric fuel pumps. I might be able to dig up some pics on the forum from when i had to do mine.
Im havin problems with mine too, i cant seem to catch any spark. tried 2 diff coils and still nothing,..... GRRRRR a year without my truck and this is my setback!
Also i have now tried 2 diff coils and still nothing, any one have wiring diagram? i have 3 wires coming to this resistor and dunno what or really where they go
