Everything worked as advertised with the reinstallation of the radiator but now my instrument cluster lights arent working, all othe interior lights seem to be fine except for the cluster. I did have to jump the truck after the radiator install, not sure if that has anything to do with it

Turn on the light switch, see if the parking lights and tail lights go on, they are all on the same circuit. If so, turn the little ribbed wheel switch on the dashboard, the dimmer.

On my B2200, I lost instrument panel lights, parking lights, and tail lights simultaneously, bead headlight switch part of the combination switch. There's two types of those switches (a 4 and a 5-terminal one), so either make sure to get the right type. Better yet, you can clean the contacts on your existing headlight switch.
