Lmackattack Posted March 22, 2010 Share Posted March 22, 2010 Some lites, guages work; I have Tailites...runs. Need a loom or schematicDont know of any data on line. all the books have a few versions of the electrical systems with the diffrent options listed. If you truck was like mine you will have a few splices and such in alot of wires... I find that you should just replace all the exterior junction blocks and clean your grounds first and then follow the wires. I had to make new looms for my hood and rear tail lights on my 1977 RS.Trent Quote Link to comment https://www.bigmacktrucks.com/topic/13122-schematic-in-dash-forrs600l/#findComment-51769 Share on other sites More sharing options...
