hicrop10 Posted January 30, 2013 Share Posted January 30, 2013 Guys,looking for the wiring diagram for my B87.I'm sure that all B models would be the same.It looks like I will most likely be taking the cab off my B87.Looking up under the dash after I blew out 50 years of dust it looks like mangled spaghetti.There are wires that go nowheres.Once I get the cab off and the dash out of it I will be rewiring it also.Having the diagram would make it a whole lot easier and much quicker.You can email it to me.Thanks Mike Durkin md992@aol.com Quote Link to comment https://www.bigmacktrucks.com/topic/29693-b87-wiring-diagram/ Share on other sites More sharing options...
Maddog13407 Posted January 30, 2013 Share Posted January 30, 2013 the harness isnt that difficult to make yourself. take it out, mark where everything goes, trace the wires, cut out the bad and replace them one at a time with the same size. thats what i did with my B613. ditched the original harness cause it had glass fuses and rebuilt one that came out of a B68T Quote Link to comment https://www.bigmacktrucks.com/topic/29693-b87-wiring-diagram/#findComment-160701 Share on other sites More sharing options...
