Today on our Gooseneck flatbed utility trailer, we'll be installing the Pro Series Push-to-Test Breakaway Kit with Premium Integrated Charger, part 50-85-315. We'll begin up here at the front of the trailer. We're going to need to mount our battery box that has the integrated charger built into it as well as our breakaway switch. Now, there's already a couple of holes in this trailer as it previously had a breakaway switch installed. We drilled out a hole for the ground, and we drilled out the hole a little bit bigger to mount the breakaway switch to it as well as a larger hole to allow our wires to go through the frame. We'll also have to drill 4 additional holes to mount the battery box with the integrated charger in it to the side of the frame. Now, we'll go ahead and hold our battery box up into place. We'll mark the location of each of the holes that will need to be drilled.
Now that we have the 4 locations that we need to drill the hole to mount the battery box marked, we'll go ahead and set the battery box aside. We'll then take a 1/4-inch bit and drill the 4 holes out. Now that we have all of our holes drilled, we'll go ahead and begin here by mounting the breakaway switch. To mount it, we're going to use a 1/4-inch bolt with a locking flange nut. We'll go ahead and secure that to the frame of the trailer. With that done, now we're ready to mount our battery box.
To mount the batter box, we'll be using four 1/4-inch bolts, again using locking flange nuts. Now that we have our battery box mounted, we're ready to go ahead and connect some wires. The white wire coming off the battery box will be a ground wire. Now, to make our ground connection with the white wire here, we're going to use a ring terminal, which is part number DW05705-1. We'll go ahead and strip our wire back to make our connection to the ring terminal. Once that's done, again, we'll go ahead and use another 1/4-inch bolt with a locking flange nut. Now, you notice that there's 2 more wires coming off of the bottom of the battery box.
One of them is black that will need to run to a 12-volt power supply that comes off the 7-way of our vehicle. Now, this trailer has a junction box, so we'll be tying into that a little bit later. Now, the blue wire coming out the bottom of the battery box will need to tie to one side of the breakaway switch. To make these connections, we'll be using heat shrink butt connectors, part number DW05744-5. Then, the other wire on the breakaway switch will be tied in with the wire that runs back to the brake circuits. Again, we're going to tie into a junction box on this particular trailer.
Now to run the black wire as well as the connection off of the breakaway switch back to our junction box, we'll be using some jacketed wire that's part number 12-2-1. Now, depending on where your junction box is located on your trailer or how your trailer is wired will depend on the length of wire needed here. To make these connections, we'll be using heat shrink butt connectors, part number DW05745-5. Once our connections are made, we'll go ahead and use our heat gun to seal up the butt connectors. Once we've made our connection to the breakaway switch, we'll wrap that connection and the blue wire connection up with some electrical tape. Now, we'll take the other end of our double-bonded wire and connect it to the black wire from the battery box, again using the yellow heat shrink butt connectors. Now that we have all of our wire connections made, we're going to go ahead and take a piece of 1/2-inch wire loom and put it over the wires to give them a little extra protection here. The 1/2-inch wire loom is part number 459075-1 and can be purchased by the foot. We'll also be using a few zip ties up here to help secure off any excess wire. Now that we have our wire connections made up here at the front, we're ready to route the jacketed wire back to our junction box, which is located just underneath the bed of the trailer. Now, when routing the wire back to the junction box, we'll use some zip ties to help secure things as well as some 1/4-inch loom clamps to help secure it to the trailer. The 1/4-inch loom clamps are part number A0250. Again with these loom clamps, we'll be using 1/4-inch bolts and locking flange nuts. Now that we have our jacketed wire routed down to our junction box, we're ready to make the connections here. We'll take our double-bonded wire, cut into it, and remove some of the sheath to expose our wires. Then, we'll route them into our junction box. We'll first strip back the white wire and add a ring terminal, part number 44-5310A. The white wire will tie in with the brake circuit in the junction box. Next, we'll strip back our black wire and add a ring terminal, and it attaches to the 12-volt accessory circuit. Now that we have our connections made, we'll go ahead and button back up our junction box by putting the cover back on it, and then, we can go up to the front of the trailer and test it out. Now, we'll be using our tester. When the 12-volt power supply is on and it's showing it's charging, you'll get a yellow light. If it needs a recharge, you'll get a red light, and if the battery is fully charged, you'll get a green light. In our case, the battery is not fully charged, so we get a red light. When you remove the 12-volt power supply, it goes back to blank, and with that, that's all there is to it to installing the Pro Series Push-To-Test Breakaway Kit with Premium Integrated Charger, part number 50-85-315, on our Gooseneck flatbed utility trailer. .

This break away kit is nice and easy to install. The indicator buttons on the top, are a really nice feature. It works good. 573084
Nice product but poor packaging by trailer. Product arrived damaged and since I needed to use my trailer the next day, I repaired it myself. Etrailer should have place the thin product box inside a better shipping box. They may have saved cost on their end but now have an unhappy customer. 195255
Sal F - 05/26/2016I have been having trouble with my trailer brakes and noticed that the existing battery was no longer bolted to the trailer, but was loose in the storage compartment. Since it was several years old I decided to replace the whole system. The new one has a charging system , which will keep the battery charged. I will have to do some rewiring,but that will not be a problem. Thanks . This looks like a good system and i can't wait till I get some good weather to work on the trailer. 592301
