yeah your suppose to check before you wire it up... my car the right one was the 12volt so you have to use the alt wiring diagramnjp98 said:A note to 3.8 F-body guys reading this, if you use the CUIs from MSD sometimes the instructions conflict with wiring in the MSD DIS4 instructions. Had it wired just like it said and it would run with the plug in the end, but not with the ignition box wired. The problem is that the CUI goes on top of the ignition controler and on some F-bodies the terminals are inversed, causing a problem. If you're not sure, use a multimeter to check for which terminal is hot. Overall its an easy project though. Can be done in a few hours.
ummm wierdExcell said:In my opinion, I would not waste your money on a DIS. The stock ignition system is more than adequate for whatever power you can throw at your car.
We run the stock ignition on all of our cars, including the turbo car, without issue. On my car (11.48) I run stock EVERYTHING, wires too!
