Far too much time wasted about nothing: Sorry. You are missing the point. The point? Said in the first post. Repeated in the 10th post.
I have a $300 ignition system that ran in my car for a bit over ten minutes. Then it quit. I'm looking to find out why. If others here (and where else are you going to find more Mopar folks?) have run solid wires with an FBO setup for years with no problems then the likelihood of my running one for ten minutes just to see if it worked...and it didn't...solid wires are not the issue.
Switch vs ECU? The FBO box is a bit more than a switch. It is NOT an engine control unit for sure but it's got 'lectronics in it that a mopar-style 4/5pin box does not.
