Turn signal problem

[stubby1962]

Hi All:
I have a 65 SWB/SS. I put a ZR-1 roll pan on it and cannot get my turn signals straightened out. I have parking lights, brake and one turn signal, But when I turn on the signal to either direction. Both indicator lights on the instrument cluster blink, but not on the front of the truck. I have all the lights grounded very good,(or at least I think I do). I had a similar problem before on a 76 Chevy truck I was hooking up a trailer light to and ended up getting a converter for it. Well I bought a converter and installed and still no luck with them. I have unpluged the front harness to the lights and The back lights work right, but the indicater lights still flash on the instrument panel..I've thought about splicing into the rear turn signals and running them up front to get the front blinkers working. Any suggestions would be greatly appreciated. Thank You and God Bless US All.....John
