Sounds like a problem with your choke. It may just need to be cleaned (linkages and all). If the choke doesn't close after reaching operating temperature, the engine will rev high. This indicates a choke stuck in the open position. Also, you may need to look for a vacuum leak if cleaning it doesn't fix it. On a 1981 GM product, I'd expect the vacuum hoses to be stiff and cracking.

Are you needing advice, links, tricks, or all of the above?
If it's advice you want:
If you are not buying an after market harness and all of the oem wiring is intact replace one wire at a time from the component all the way back to the fuse box. Its tedious but, it's a sure fire way to get it right the first time.
Secondly, I'd by a haynes manual or some other wiring diagram. Study it for at least a couple weeks or until you are completely comfortable taking on the task.
Color code your wires and label both the old and new ones with paper tape and a permanent marker so that you know what each one is for.
Last but not least, make sure that the battery is disconnected... ;o)
