American Autowire question??????????

I'm starting to wire my 51 truck. It has a 350 crate engine. The plug to the alt. wont fit my alt. The Wiring kit came with a plug in for the alternator that won't fit mine. The kit plug had two connects but my alt. has 4, one larger and three smaller.

Send them an email with a picture and other identifying info - my contact there is Don Bock and he will generally respond within an hour or so - but not until Monday
