The stock LS1 wiring harness plugs in easily to the LS1 engine and computer

What I am looking for is the wiring diagram to tie in a 1963 pickup to this LS1 engine and computer. How do I wire in the 1963 GMC ignition switch to the LS1 starter, computer, and alternator ? Anyone have a wiring diagram ? What did you do with the extra original wires going to the original starter ?

Do I worry about the computer knowing the oil pressure ? Or do I tie I the oil pressure into my gauges manually ?

Do I worry about the computer knowing the engine temperature ? Or do I tie the temperature into my gauges manually ?
