can any one give me some insight or blue print on wiringing up 455 engine in 72 cutlass such as color codes and what gage wire needed to crank car in safe matter don't want to burn her down thanks

I can't get any help I guess

I am looking for the diagram I have, but can not find it.
What is missing, every thing?

 

May I suggest getting a Chassis service manual and check Rock Auto which has the engine wire harness.

 

The Chassis Service Manual and Factory Service Manual are invaluable. I ordered reprints from Fusicks and I am happy with mine. The binding on the FSM came apart but otherwise they were an excellent investment.

Besides a Service Manual, this is another GREAT resource to have at your disposal.
