I just purchased an RC23 model powerwinch and
would appreciate Any advice on how to setup the
wiring on my mercedes ML320 so that I can plug it
into the truck the same way I plug in the trailer to the
truck which is with a 7blade plug. I know ineed to mount a
Plug and wired on the truck and then a plug on
the winch wires that will allow it to connect. what wires/plug
Do I need on the truck and where do I connect them and
what plug do I need on the winch wires

I used an Anderson SB 175 connector which comes up into the bed of my pickup. I had two power winch socket and plug connectors fail on me in one year. No problems in three years with the andersons.

Be careful of the AMP draw of the power winch and the wire size for your truck. Most power winches have a dedicated cable from the battery, with a fuse, direct to the connector for the winch.

I have a Lutton/daison and they have a vehicle wiring kit available to wire directly from the battery. Uses the Anderson clips, just like the ones on the winch itself.

I have a plug tucked under the rear bumber. The positive goes to a 60 amp circuit breaker and then to the battery piositve.( I used the positive terminal in a chevy truck, not the actual battery terminal.) I bolted the circuit breaker to the back of the positive power distribution post in the truck. I mounted one of those super-heavy duty alligator clip to the neg/ground and have that clipped to the ground on the alt. in the truck. I did run the cable in an old garden hose along the frame. Been there three years and no problem yet. These wires can get kinda hot, I wouldn't use just any small wire. My dad always just went and bought two extension cords and used them. Seemed hokey, so I payed the 50 for the kit from lutton/daison. He was able to get the Anderson clips from napa. To me the worst was getting all that through the frame of the truck.

A fully charged battery kept in a battery box in the back of the truck would work fine as well, especially if only needed occasionally.

This is the easy way to do it....

I wired one within the specs and used 8 gauge wire, and it was marginal to say the least. Damn, those winches draw some power. Unhooked it all and just used a battery in a box in the bed. Took it when we needed it...

I have a roller trailer and a 23 maycraft ph. I never ever since 2000 when the trasiler was new ever got the rear axle wet when loading or unloading. I power the entire rig off and then the entire rig back on. Takes about three minutes to pull it completely up.
The ramps around here are funky and lots of the time I am one of the few that can launch w/o paying attention to the tides because people don't have enough room to float the boat off of their trailers.
If you are using the winch this way, a battery will not work. I tried and had to use jumper cables to the truck battery after I killed the battery in the back of the truck(group 27 interstate). I leave the truck running. If I do not I will kill the truck battery. Plus it goes on about twice as fast with the truck running.
One thing I have noticed is when using a Z71 versus a non Z71 to use the winch. The Z71 pulls it up about 30-45 seconds faster than the non. I was told that this is due to the Z71 coming with a bigger capacity alt. The chevy dealer told me they put a bigger alt in z71's because you might use a warn winch, offroad lights etc. Could be bull I don't know, but the Z71 definitly pulls it up the trailer faster.

The way my Dad did it was ..He wired the factory winch to vehicle plug to a long set of jumper cables. When he went to the ramp he would just pop the hood and connect the jumper cable ends to the battery and run the wire down the truck, over the side mirror and plugged into the winch. When was done he just threw it in the back of his truck and closed the hood. Easy enough I guess. Hokey to me though, like the extension cord deal.

I put the breakers directly to the battery and ran the cable to the left rear corner of my pickup bed I have a grommet which protects the wires from chafing. I grounded right to the frame of my truck. No problems with what I've done and the connector in the bed has 6"s of wire plus the 1.5" x 1.5" connector. By keeping it inside I have zero corrosion problems.
