I have a Mopar orange box ECU on My Coronet...should it have a single or duel ballast resistor?

i think you are refering to 2 prong vs 4 prong ballast resistors?if so ,either will work fine.you would not run 2 ballasts in series,your voltage drop would be too low.the 4 prong ballast just allows for more hook up points.most pre 70's cars use 2 prong.

Yup...'67 Coronet is right. Your set up in the '69 Net would be a single. I have the orange box in my '68 and it's single as well.

Thanks Guy's.....think I have tracked down My problem to a (Dodgy) bulkhead plug....
