Is a ground wire included in the 4 wire?

Yes, the ground wire ties in to your bolt that's coming off on one of the rear tail lights

It has a short, approximatemy 24" white ground wire as part of the trailer harness. The kit does not come with a ring terminal or anything like that.

Yes, they have two feet of wire to connect the chassis on the trailer plug(female pin) and three feets on the side of the vehicle(male pin)

I should still work! I am assuming without seen a diagram you will have one wire to the power source and the other two wires will go to your wire in and your wire out and you will probably have to piggy back that the fourth wire if the fourth wire is not a ground

As I recall it just had two; a black and a white. No ground wire. It is for lamps rather than house wiring.

Sorry! Still didn't install yet! But I would say it's not grounded or wired properly!

yes, if you wire it correct. there are only three wires, ground, positive and negative.

No wire is included. As I remember it did include a relay. Use size 16 or 18 wire to trigger the relay and #12 to carry the load to the horns. The horns will pull a lot of current (amps) when activated and using #12 wire should eliminate any significant voltage drop.

i tried it both ways, with the green connected to ground and not connected to ground, the unit worked both ways, i do not believe this green wire is a true ground wire.

It is grounded through the studs - no ground wire. It will only work when studs are mounted!

I'm not sure but mine came with about a 4' 3 prong wire. So no I did not have to hardwire mine.

Correction...my mistake . It takes does not have a ground wire. It grounds itself when bolted to the car. In my case, I have a fiberglass body so I had to run a ground wire to the bolt. All in all easy install, and for those who claimed bad reception probably should check their power connection. This thing is awsome!!

Hi, it counts on your wiring. If the box is ground and you use the screw in the loop then yes it will be ground. If the box is not then of course a ground will not just appear from no where.

Yes the wire is included, but the relay is not. I am not handy at all and was able to install it off the battery. Worked we'll.

Yes, it is a wired unit, I did not install my electrician did so I do not know if there are four (4) wires. It does work very well, and I am please with it. There are no batteries requirements for this unit.

Older installations won't have a matching ground wire. The ground wire is for safety, but not strictly necessary. Simply cap it off as you do the other leads and be very careful none of the wrong wires touch each other when you push the box in.

Both are 4 conductor, but the solders in mine were crap and the thing fell apart one time when I unplugged it.The 4 conductor functionality also didn't work very well.

yes everything is included you may need to extend power, ground , and trigger wires depending on your hook up

This set, as in all lights, is 2 wire with ground. The ground wire is connected to the mounting screw which grounds it to the body. The other two wires are 1 - for tail lights/stop lights and the other is for turn signal. I don't know where you are getting the 4th wire but it is not needed or used. Easy install.
