[QUOTE="Adrenlin, post: 1799260, member: 51757"] [FONT=Calibri]The wiring diagram that comes with the unit can seem a little daunting at first, but it isn't that bad if you're just wiring this up to inflate tires, like I planned on doing. Additional wiring is available for air lockers and additional switches, and wouldn't be used in my scenario. Focus on the main harness first. It's the larger plug. There are two red wires, and two black wires. The red wires are the same size, and the two black wires are different gauges. I had to extend the harness to reach the front of the Raptor. Use 10 gauge wire for the red wires, and 8 gauge for the heavier black one. The smaller black wire appeared to be 16 gauge. You can always use a heavier gauge (numerically lower) wire, but never use a lighter gauge wire to extend a line. When extending the harness, you'll want the fuses close to the battery. So I cut the fuse blocks from the harness, leaving some extra wire to facilitate tying them back in later. Since you will be extending the wires, snip any connectors off to make the next step easier as well. You'll need to drill a hole in the drain plug, and pass the wires through so you can access them from the underside of the truck. On bed covers such as the Undercover Armor Flex I have installed, this is not really different than running drain tubes through the drain plugs. You can see this in Figure 5. Once the large harness is through the drain plug, focus on the smaller harness, this is the control harness. This harness has two wires, one purple and one black, at the plug that connects to the ARB compressor. These are the only two wires I used for my configuration. One the other end of the harness there's also a green and yellow wire. You'll also find green, black, and yellow connections in the middle of the harness as well. I snipped all of these off, for my application as these are used for additional switches and air locker solenoids. I've modified an image of the wiring diagram from the manual, in hopes of better illustrating what is, and isn't used, on the harness. I mentioned that I only used the purple and the black wire. The black wire is the ground wire, and the purple line is the switched power that toggles the compressor on/off. The purple wire should be tied into one of your Raptor's upfitter switches. In my case, this was upfiiter #6. Since this is just a signal wire, current is minimal. So I used one of the switches with the smallest amperage rating. This leaves the higher amerage switches free for other accessories. Once the smaller harness is through the drain plug as well, extend your harnesses and begin the task of getting the harnesses to the front of the truck. I used some 14 gauge wire I already had on had to extend the smaller harness. You'll be running a total of six wires to the front of the truck. Two red, three black, and one purple. I fished my wiring along the inside of the frame rail. Once you get close to the front, you'll find a grounding strap that connects the body to the frame. I utilized both ends of this strap for grounding. I crimped a connector onto the 8 gauge line and used the factory bolt to clamp it down at the frame end of the strap. The other two ground wires were tied together and secured at the other end of the strap. I used wiring loom and zip ties to secure and protect the wiring. See Figure 6.
