89-91 front end harness

[tylervalo]

I've got an 83 cab and the PO put a 89' front end on it, how do I need to PROPERLY wire up the lights? Would it be best to cut the front harness from another 89'-91' or can it be done with my current harness?

Does the current front clip have wiring in it running to the firewall? If so is that wiring from '89-91 or '83? I'm a big fan of not cutting wires whenever possible. I have had to unpin the wires going to the cab at the backside of the fuse pannel and move them to a different spot that had the correct power going to it, this wasn't because of a newer front clip but for somthing else that wasn't working.
