ok copper it is.

my turn to redirect the thread.
The new accel wires i baught are the ones you have to make youself, they are pre cut all i have to do is put the 90 degre boot on. Anything to look out for?

I talked to a guy who made his and he had all types of problems, but he isn't the brightest person i know either.

 

do i need some kind of special crimper or can i just use vice grips or pliers?

 

Special crimper for sure. Then, you still have to be careful to not cut the silicone. I've never seen self crimped wires that would withstand being removed once installed. The terminals always pull off the wire. Hopefully you have better luck or at least things have improved since the last time I tried probably 20 years ago.

 

I used a pair of pliers on my Taylors and it was a PITA. Supposedly the crimper helps a lot.
