Please help: I Need 1966 Plymouth Barracuda master cylinder and pigtail electrical piece

Hayley, those headlight switch plugs seem to be a problem area with our older Cars. The problem is there is quite a bit of amperage drawn through them, especially if you install aftermarket headlamps. I'd suggest doing the Mad Electrical headlight relay mod after you install the new pigtail and switch from Whitepunk. It takes the load off the electrical system and lets the relays do the job. It also makes the headlights quite a bit brighter. It's not hard to do either.

Here's a link to it. They show doing it on a GM I think but the process is the same.
