2000 W900 Wiring Diagram

I do not. I used a test light and temporary jumper wire and poked around where the wiring comes outside of the firewall, behind the windshield washer tank

 

I appreciate it. We are swapping the motor in this truck, so between that, the goofing wiring and the fact that my husband/chief mechanic is a purist when it comes to his work, we have to have a diagram. To make sure it was done right, when no one was around to whine about it, he stripped out every piece of NON-factory wiring in the cab and under the hood! No more lost loads because of electrical issues. LOL

 

Having same problem no head lights but have marker and box lights when I hook up the 8 connector harness it blows the fuse any help
