Hi all. What is the benefit of the accessory harness versus a fuse block? Is it just to cut off power to accessories without the key being in the "on" position?
Yes, for the most part.
Assuming you are talking about the one with the red connector and 5 or 6 lines?
The harness provides a keyed-on positive for relay control and what not.
Mostly so you do not have to cut/tap the OEM wire harness.
Its a small amp line, 15a max shared between that and the CIG/ACC socket.
If you dont have a lot going on, it could power a set of cubes and many small LED light bars on its own.
That will work.
Yet, I still highly recommend having your winch on a keyed-on source tho.
Did you have a good connection when you tested?What I find odd is there are 3 different voltages at that red connector, but the acc harness only uses the 12v one. Notably, there is a 5 volt source that would be perfect for usb devices.
Did you have a good connection when you tested?

What Trigger said....Wouldn't that be 4 x 12v and 2 x Neg...4 hots and 2 grounds provided and it just plugs in, well worth $10.
