Doc,
Thanks for the feedback on my post. Although I didn't specifically state it, you are correct that the brighter filament should be for the turn/brake circuit. The rectangular light uses a single 1157 bulb that has a double filament. One is 3 cp (for the tail light) and the other 32 cp (for the turn/brake).
After playing with the wiring for days, I guess I was just happy to get the tail, turn and brake lights to work. I can't remember whether the brake lights over ride the turn signals or the other way around but will test some more today and post the results. Even then, I will be the first to admit that electrics is not my strong point. I followed a wiring diagram in Tex Smith's "How To Do Electrical Systems" but it didn't detail the type of turn signal assembly to be used.
