Second battery to be fitted this weekend.

I am fitting a second battery into my SN 1994 this weekend as i have added a new amp and stereo etc.I am looking for a wiring diagram and a list of items required for the job. I have a perko switch to add into the mix. So any diagrams or pics would be great.

Where are you going to put it? Thanks

Planning on putting it in the hole in the floor in-front of the existing battery and the switch along side the drivers position.

I am considering adding a second battery too. That "ice chest" is practically useless anyway. You will probably need to drill a 1-2 inch hole in it for wire access. The perko switch should give you wiring directions, no?

Robbie- Here are some pics for you. 8 batteries total going into perko switch.
