Next up on the mod list is the battery relocation. I know I need a sealed box w/ a vent tube. I also know I need a cut-off switch. I have the old style alternator/regulator system. So my question is, can I just run the battery cable to the cut-off switch, and the other side of the cut-off to the starter solenoid? Or do I have to wire the alternator to the switch somehow? If anyone has a schematic of the wiring, that would rock.

Also, how do I mount the box in the trunk? do I just drill holes in the box and bolt it down, or do I need a tray/straps/something else? Thanks a bunch!

You have to run the alternator wire to the battery side of the disconnect switch so the switch will kill your engine.
As far as mounting the battery it has to have a min of 2- 3/8" dia bolts holding it to the floor of the trunk, no "J" bolts.

Also you don't need the box if the passenger compartment is sealed from the trunk by metal. Behind the seat and the package tray. This is a good idea anyway since the floor of your trunk is the top of your gas tank.

I'm not following. If I put the kill switch in between the battery and the starter solenoid, how would the alternator keep the car running if the battery was shut off?

trust steve, the car will keep running. the alt wire goes on the battery side of the switch. the hot wire has to be on the switch, not the ground . start your car, take the cables off of the battery, take the battery out of the car and throw it away and your car will still be running.

If you disconnect the battery while the engine is running what will happen? Yep, it'll keep running 'cause the alternator is supplying voltage to the engine. If the alt wire goes to the battery, then when you disconnect the battery the car will die. OK?

Ok, ok, I believe you.

So I would have a cable from the battery to one side of the switch, and a cable from the alternator to that same side of the switch, and the other side of the switch to the solenoid, is that right?

What about the voltage regulator? How will that come in to play?
