Going from lights to gauges

[rcbildr]

I'm working on my old 83 1ton chevy and the truck originally had the idiot lights instead of gages. I'm storing a 76 parts suburban for a friend of mine and he said I can use whatever I want off the truck. The burb has the factory gages. If I pull the cluster and sending units off the burb and put them in the truck, will there be any changes to the wiring needed? I've been doing a lot of thinking about it and the only problem I think I might have will be for the volt gage...only really care about the oil pressure and temperature gages anyways. Any help will be greatly appreciated. Thanks!
