Had a moroso one, and a flaming river push/pull switch with the external rod. If your track is strict at all you will need stuff that is NHRA/IHRA legal. Which means, no you cant use that cheapo box summit sells.
My settup worked great, kinda wish i kept those parts so i could put the 03's battery in the trunk, o well.
Oh yea, i got the moroso batt box from a board member, i forget his name, but he had a website and sold some mustang parts. Real nice guy. I got the switch from summit, and wire for the battery stuff from a local welding supply place.
