I wouldn't use the factory style wires. I just redid mine not too long ago to take care of slow starts after it was hot. I went to an audio installation place and bought really heavy guage power and ground wire, 0 & 2 guage iirc, and placed my own ends on. It's that really flexible high quality wire. I measured what I needed and cut it a little longer and routed it the way I wanted it to go. Wrapped the full length in the high heat reflective tubing and this thing fires off crazy fast at the flick of the key even when hot.
