K, question for you audiophiles... I drive a panel truck (step van) for work. It has no leads for a radio and I want to hook one up.

The idea is to get a headunit, hook up some quick disconnects to the power wires of the head unit, and just jam them into the fuse box until I find power... with a fuse on the headunit, I don't think I'll fry it...

Should also be noted that the fusebox cover has been long lost, along with it the diagram labeling each fuse port. As far as looking up the diagram, I have no idea where to start, there are 2 manufacturers... chevy made the chassis, grumman olson built the rest... so no idea where the fusebox came from.

Maybe multimeter could fit into the fuse ports... instead of guessing with the headunit...

Comments, concerns, better ideas?
