Be sure not to allow the hot wire to touch the mufflers when the car is lowered and wire tie the hell out of them and use a grommet. They have a way of rubbing everywhere and shorting out if not done well (like mine). Be sure to at least ground it to the frame if not all the way up to the block too or Engine/EEC/idle problems can occur do to low voltage readings. Been there, done that too.
Let me add one critical piece of info to Fordman's informative post:
Please remember that the rear suspension WILL COMPRESS and that might
cause the hot wire to come incontact with the hot tailpipes even when it looks like there is no way in hell that it could touch.
Yes, this is what happened to me and it nearly burned my car to the ground.
As far as performing this mod: Everything you need can be bought somewhere local. I used 4 gauge welding cable for my hot and ground (and its actually better than what comes in the kits. Have you ever seen how tightly wound the welding cable is?
) I bought it for around $.75 a foot.
By the appropiate "J" hooks at a local hardware store, and a local fishing or sporting good store should have battery boxes.
Not sure if this route is cheaper
than going with a kit, but I like the idea of running the better grade cable than what you get in the kits.
