1984 Dodge Ram W150 Wiring Harness - ramforum Nov 03, 2015So I found an 85 Dodge Ram D150 with the simpler computer box and vacuum advance and pulled those and the wiring harness. I've found plenty of diagrams for the bulkhead connector of the old harness and was going to try to wire it up to the new one I got. But I can't get it right and nothing really works. I'm thinking the diagrams don't match up.My 1991 W150 | DODGE RAM FORUMMay 19, 20191990 W150 Wont Start | DODGE RAM FORUMAug 21, 2017My 1992 Dodge W-150, and some questions | DODGE RAM FORUMMay 06, 2016Carb Question on 1988 w150 318 | DODGE RAM FORUMJul 27, 2013See more results 1985 Dodge D150 Wiring - Engine - Mopar Parts Giant MoparPartsGiant offers the lowest prices for genuine 1985 Dodge D150 parts.
