Hi, I want to add an aux fuse panel so I don't have to splice into my existing wiring to add extras (CB, GPS, etc). I would run a fused wire from BAT + to the fuse panel, then I would like to add heavy-duty inline switch between the fuse panel (always on) and the accessory outlets to prevent drain. Should I use a switch or do I need a relay as well? The extras won't be drawing much power, I'm only thinking an overhead light, CB, GPS, and maybe a 110V inverter. Any help would be appreciated. Thanks!

You should be ok to run just a switch. Make sure it is rated for enough amperage for what you will be running on the outlets.

I put my aux fuse panel behind the driver's kick panel in my truck and it fit perfect. I'm also going to run a cable to have one in the back as well.

I used a painless wiring kit with 3 fulltime hot and 4 ingition hot wires for all my accessories. It was a little spendy but it saves alot of headaches as i add more, comes with a fuse block, relay, and all mounting harware, keeps it clean and i dont have to remember to flip a switch to not drain my battery.

Jake, got a link? I want one of those, I saw a couple on this site yesterday.

I have the same one, let me find the link at Summit racing real fast...

...This is it: Painless Cirkit Boss 7-circuit Auxilliary Fuse Block, has 3 constant-hot circuits and 4 ign-hot circuits. At $60, it's still worth every penny. It has a built-in relay so all you have to do is tap into an ign-hot source like your cigarette lighter or ignition system somewhere. I tapped mine into the ECU's power cable because I only wanted it to turn on when the key was in "ON" rather than "ACC," but tapping into the cig lighter would work great for CB's and the like.

I run my 350 watt inverter off of two of the constant-on circuits in parallel, and then use the ign-on sources for my Piggyback ECU, Wideband O2, and Gauge.
