I just got the car a couple months ago. Got it started so it would idle and it's been down since then while I repair some rust and replace the fuel tank and line. I notice that I seem to have an extra part connected to the ballast resistor. Looks like a cap or condensor from a points type ignition and it is wired into the plug on the ballast resistor and then grounded under the bolt that attaches the electronic ignition control box to the firewall. The car is a 73 Cuda with a 340, with electronic ignition. I'm curious as to what it's purpose might be? Is it benign or could it cause an issue? The wiring harness is a mess and it's obvious a previous owner was a hack with the wiring. I'm a bit hesitant to touch anything at this point because it was running, but I have a new engine harness on hand to install once it is back down on it's wheels.
