Mack truck wiring diagram

Twisted ยท 2016-06-29 17:50

He folks I have a 1987 Mack MH633 with some wiring issues. Can anyone point me in the right direction as to where I could source a wiring diagram? There have been many "repairs" done by previous owners that I'd like to make right. Thanks Twisted

    Mack keeps archives of pretty much every truck ever built. They can pull line sheets etc. They even sent us info on our 1926 AC! The number for the museum is 1 (610) 351-8999. They're closed on Thursdays so give em a shout Friday. Junkyard

    Thanks guys. I tried all of the internet and the Mack site as well with no luck. I'll give those links a try. Much appreciated. Thanks.
