Default 12v Constant

I'm looking for a 12v constant for my bottle heater. I thought one of the lugs in the center of the passenger floor fuse box was one but I guess not. Any other source other than running to battery?
Thx,

Sarge

Have you used the AUX 12 VDC power wires that are in the passengers foot well that are designed for this purpose?



Its a 20 amp circuit. Theres a switched wire, hot all time wire and ground.

It uses 20 amps so I need a little more and use a 25 amp fuse. Can I add a tap to a 30 amp circuit in the fuse box?

Thanks for serving by the way!!

If it were me,, I would run a feed wire from the B+ terminal on the engine compartment fuse box directly to the tank. Its really quite simple. You can fuse it right at the terminal:







You can use a coat hanger and snake the wire in thru the fire wall gromet and it will look factory!



I used this set up to power my heated seats and it worked fantastic.

Getting the wire to the rear is easy. Run it under the door sill where the rest of the wires run.
