the car is a 1967 v8 car. the coil wire, can i use it for a 12v ignition power. need a 12v source to run the computer for my Ls1 swap. what is throwing me off is, the fact of how small the wire is and on a wiring chart, it says that it is a resistance wire. what do they mean by that. can i use this? or is there some where better to get a 12v ignition. the car is still using the factor wiring loom.
