Trying to finish electrical conversion. When purchased wiring was in a big ball...so far I bought a new engine harness for a camaro cause the guy told me since I am using a 400 chevy sb the wires would be the right length.

My questions are: Are all newer alt. internally regulated and if so do I need the external alternator regulator orig. installed ? What do I do with the wires if eliminated? What other wiring would normally be changed when switching to an Accel dist. and coil? Thanks for the help! Bob
