I recommend more than that; DC's OEM kit specs relays that draw
directly from the battery post, AND seperate fusing for every circuit
beyond the rear bumper. It also plugs directly into an existing rear
wiring harness using waterproof connections. Very nicely designed.
Unfortunately, unless you use a DC OEM receiver with the
specially-designed waterproof RV outlet box on the side, you'll have to
wire your own outlet.
Consensus: use seperately-fused circuits for trailer power, and/or
relays for all circuits if possible for the best protection and
reliability. Wire everything directly from the battery, not from
existing circuits. It's a PIA, but you'll never have a problem with it
later on if you put in the effort.

Does the existing harness have a clean power line for their box or is a
new line required also?

Re: Help- Identifying wiring for lights.
It uses a custom 'pass-through' plug that hooks into an existing
harness up underneath the left-rear fenderwell. Nice design. No
splicing or wire-cutting required. The relays and pass-through
connector are all one single waterproof unit that all nylon-tie
together and tuck neatly back up underneath the fenderwell.
Three wires route along the frame rail to the engine compartment:
ground, 12V+ and trailer brake actuation, which also has its own relay.
The fused 12v+ lead is connected directly to the fuse box + terminal,
and supplies power for all trailer lighting and brakes. A standard RV
connector is used for the trailer hookup. DC's OEM receiver has an
insulted RV connector box welded right in, so it was a perfect fit.
It sounds more complicated that it actually was and I was surprised at
how easy it was to install. I loathe wire-tapping/splicing - it always
manages to corrode and cause problems. For about $35 bucks, this is a
great way to custom-wire a trailer hitch on a TJ. I bought mine from:
