Sorry can't help you with that - However it is a bit poor that their is only one power supply on the front dash - Will have to get one installed at the rear for things like fridges etc. Yes, I was a bit unhappy about being charged $150 for a rear power outlet for a so-called off-road vehicle when my VW Golf pavement machine has one as standard. We are spending $20,000 on all the extras for our new Merlot GXL TTD LC200 eg ARB Merlot Deluxe bull bar, IPF spot lights, ORS double ally drawers + fridge slide (80l Waeko), Long Ranger 180lt fuel tank, ARB roof rack, KAYMAR twin rear wheel carriers, six STT Coopers, and a UHF two way, oh and a thumper rear battery pack. Then off on the gunbarrel, Canning stock route back along the Tanami track. Plenty of paint protection.
