Does anyone know if the truck is optioned with the High load auxilary switch panel,is the 500 amp Nato plug prewired to both the front and rear of the vehicle?

Yes it is. Front is accessed under font right wheel well rear has a nato plug next to hitch receiver.

On my AU Spec the NATO circuit is wired to a NATO plug in the rear, the front is wired to the installed winch.

This thread has lots of information on the NATO plug.

Rear NATO plug looks like this (removed from car).

Hey Doc - if installing a winch aftermarket, in your opinion, what would be the preferred hookup?… To the supplied hi-load under the bonnet with all of the module restrictions of the vehicle computer, or directly to the battery? If going directly to the battery, could we just tap in to the jump post under in the engine bay, or would it be better to run a dedicated line back to the battery itself? Thanks in advance!

Actually the winch wiring is connected to the jump post box, through a 150amp auto reset circuit breaker. I have all this wiring in my car even though I don't have a winch. Following post shows position of the breaker next to the jump start box.

Subject to the Doc's further expert advice and the winch power draw not exceeding the circuit breaker limit, I'd be inclined to hook it up to the existing wiring to keep things simple.

Ahhh… I was under the impression the factory winch was using the hi-load in the engine bay

I would go to my autoelectrician for a winch, specialist knowledge for that accessory. I have never installed one myself - winches are above my pay grade.

Warn specs for a 9500lb winch is around 400amp current draw at full load. Infos specs 500amp winch circuit and this is likely to be an intermittent load. Most winching only requires full load for a short time and the majority of winching is not at full load so current draw is less. The main concern would be the factory cable size from the battery to the front of the car as the longer the cable run from the battery will cause more resistance and heat in the cable at full winch loads. It may not be a concern for a winch under 9.5k lb but if you wanted to go to a higher rating or high speed winch that draws more current cable size could be an issue at full loads for long periods. The work around for a higher rated winch is finding one with deeper gearing that will be slower but will reduce current draw. The other item I have installed with winches is an isolator close to the battery as possible to switch off the main cable mainly for protection from vandals an frontal accidents. It is good to keep the number of power cable joints to a minimum but in some installs this can be difficult. Imo connecting to the battery is a better option this allows the winch to be used in an emergency irrespective of what parameters need to be met by the car to be able to winch. Like TheDocAUS says consult an autoelectrician for further advice if having concerns.

Appreciate it! I would definitely have it installed by a professional, but here in south Florida, it’s a bit difficult to gauge the level of ’professional’ with respect to intricate wiring. It’s almost safer to find someone in the marine industry with respect to wiring. Either way - thank you for the input, as my goal is to understand the process fully before having anyone perform an install!
