Radiator Cross Referencing

[LuckyRabbit4]

Sorry I haven't been in the thread I started -___- this truck has been throwing more and more at me to fix before winter HOPEFULLY.

I'm buying a Champion full aluminum radiator this week. New water pump and thermostat plus heater hoses.

Next in line..... wiring. I have wires everywhere not connected to anything with no clue what it's suppose to look like. Almost worth it to buy a totally new wiring harness and do it myself from scratch. but no. no.

Any help on things to look for, just in general would be great. Parts that are notorious for going bad, cables/wires/hoses/tubes that seem to have issues or absolutely need to keep an eye on. New to working on old vehicles so any advice is VERY appreciated.
