Pro Comp Motorsports Series Dual-Output Relay Wiring Harness
The Pro Comp EXP76400 wires a pair of off-road lights to your 12V system the right way: battery ring terminals on one end, a 12V relay and inline fuse holder in the middle, a waterproof switch for the cab, and two Deutsch DT 2-pin outputs for the lights. It is rated for loads up to 30 amps at 12V.
Deutsch DT plugs are the standard on Pro Comp's lights and pods and on most other aftermarket LED lights, so this harness works as a replacement or for a second set of lights. Leads are long enough for most trucks and Jeeps: 20 inches from battery to relay, 108 inches from switch to relay and 114 inches from relay to the outputs. Pro Comp covers it with a limited lifetime warranty. See the full Pro Comp lineup.
| Spec | Detail |
|---|---|
| Part number | EXP76400 |
| Maximum load | 30A @ 12V DC |
| Outputs | 2x Deutsch DT 2-pin |
| Battery to relay | 20" |
| Switch to relay | 108" |
| Relay to output | 114" |
| System | 9-14V DC |
