The Mack museum is your best friend. Your truck may have a wiring diagram on the inside of your electrial breaker cover, at least my 89 MH does. The museum does not charge but you should make a donation to them.

I probably have the wiring diagram will check tommaro if I can find it i could make a copy, are you looking to fix something specific.

You can find the manuals on Ebay. I have full color wiring diagrams for $10 (copy and mailing cost).

Hi !

I have many wires not connected and somes have been cutted , I have no shutdown buzzer or light that comes on

even if I remove one wire out of the radiator sensor !! so I'm a bit scared of what can happen .

Also looking to find a 1989 or 1990 operator's handbook ( TS57500 ) . I browsed the web google bing ebay and nothing pops out .

so still on the look for it .
