i use to have a rochester carb on my car, there was a wire running to it i believe to advance the engine when the ac was turned on, i now have a 4175 holley on it, it there somewhere else to connect this wire to make it work ? Thanks.

 

youll need a kicker solenoid for a holley

 

would you happen to know the part number or where i can find ? Thanks

 

Look up an AC kicker. They're pretty common. It's just an adjustable solenoid basically.
Try summit

 

are they universal ? i do i need one specific for my holley carb ? Thanks

 

Universal to all holleys

I just found a handful on summit

search under brand "holley"
department "air & fuel delivery"
Part Type: "Carburetor Solenoids and Brackets"

There you'll see the brackets, and solenoids. You're looking around $100 when the smoke clears.

 

perfect, much appreciated
