i have a 1987 pontiac Trans am and i want to replace the positive battery cable on it...the cable i got from autozone had the one big wire going into the side post and on little on with a wire crimper on the end..now the problem is, my cable i have on the car now has 3 leads going to the side post, the big wire and 2 smaller wires, i am wondering where i can get a 3 lead cable that i have on my car...

 

Easiest is to crimp your own.

 

Been there, done that. Run double 12 ga. wries off the single 10 ga. pigtail that's sticking out of the new battery cable.
