I just finished getting my ARB frig/freezer out of box, washed, handles attached, transit bag around it. I hooked it up to house power and I cannot believe how quickly it is cooling down. What a neat product!

Since I need to convert my rear aux plug to constant power, is there a way I can do this myself? I have the D2 workshop manual and if "how to do it" is in there, I have not found it yet. I need to get familiar with my wiring system anyway. Does anyone know how to do that??

Thanks, Jamie

The best way to do it would be to simply pull the plug out, cut the hot wire on it and run a new wire directly to the battery fused accordingly. Check out the specs on the fridge and figure out how many amps it draws at 12V. To do this divide the wattage by the voltage. That will give you the draw of the fridge. For example: 4 Hella 4000's at 100 watts each divided by 12V equals a little more than 33 amps. That's why people that put all 4 lights on one 30A relay end up replacing a lot of them. This way it is a designated circuit only for the fridge and you shouldn't have any problems. The hardest part obviously is running the wire to the battery in such a way that it is out of sight and protected. Good luck.

Jamie, If you have a FAX I can send you a wire diagram for that circuit. The color won't transfer but it's not a complicated circuit. eMail me your FAX number if you want it. But as Steve said, make sure you have enough power by checking what your ARB box will draw. The dedicated circuit is fused at 25A.

I did the same thing for my Engel. I took the existing wire that goes to the rear aux plug and tapped into the constant power circuit that is fused by a 30 amp (?) fuse in the engine compartment. If you could add an additional in-line fuse if you want. I think the original circuit is 20 amp.

To access the wires, you need to remove the fuse box under the steering wheel. The aux. plug wire and the circuit I tapped are all right there. Sorry, but I don't remember the colors of the wires. Hopefully they are in the work shop manual.

I need a constant hot wire there too. But I was thinking I would but a multi cig plug (Radio Shack) and mount it in the rear window seal. I would wire it directly to the battery with a fuse. I've already set up a fusable block near the battery. That way I have a choice of constant power or switchable with the ignition.

Thanks Al. I just emailed you my fax number. Appreciate the input and opportunity to learn more about my rover! :-)

I have the 42 qt ARB frig (MT45F-AL)

There is a placard near the plugs that says:
(AC/DC)
Fuse 10A

DC 12/24V
AC 120V 60Hz

I'll do some checking to see if I have enough power. Ideally, I'd like to convert that to a 2 plug. I have the ARB Adventure Light (only 1 amp current draw) which I use ALOT - it would be nice to be able to run both at the same time if needed.

I'm beginning to think that putting a 2nd yellow top onboard might be a wise move.

Thank you VERY MUCH, Jamie :-)
