WPS 2-Wire vs 3-Wire Trailer Light Pigtail: Which Wiring Harness Is Right for You?

Compare the WPS 2-wire (42-3081) and 3-wire (42-3080) trailer light pigtails, both at $24.99, to find the right match for your trailer's wiring.

Last updated Aug 17, 2026

When your powersports trailer's lights need a new pigtail, the first question is how many wires your trailer's light connection uses. That's the real decision between these two WPS trailer light harnesses: the 2-wire pigtail (part 42-3081) and the 3-wire pigtail (part 42-3080). Both are priced the same and come from the same brand, so the choice hinges entirely on matching the wire count to your existing wiring.

Both pigtails are made by WPS, sold in new other condition, and manufactured in the United States. The 2-wire version is part number 42-3081, and the 3-wire version is part number 42-3080. The shared brand and origin mean the only meaningful difference is the number of wires each pigtail carries.

Quick Verdict

If your trailer's light wiring uses two wires, pick the 2-wire pigtail. If it uses three wires, pick the 3-wire pigtail. Since the two are priced the same, the wire-count match is the only factor that matters.

Where Each Product Wins

The 2-wire pigtail is the clear pick when your trailer light system connects with exactly two wires. It's a direct match for that setup, and it shares the same price as the alternative. If you've confirmed a two-wire connection, this part (42-3081) is the one that aligns with it.

The 3-wire pigtail is the clear pick when your trailer light system connects with three wires. The extra conductor gives you the connection your three-wire setup needs. Also priced the same, this part (42-3080) is the one to choose for a three-wire configuration.

Product Notes

WPS Trailer Light 2-Wire Pigtail 42-3081

WPS Trailer Light 2-Wire Pigtail 42-3081 Powersports Wiring Harness

This is the 2-wire version from WPS, in new other condition and made in the United States. It matches a trailer light system that uses two wires, providing the exact two-conductor connection your lights expect. At the same price as the 3-wire version, it's the direct choice for a two-wire setup. The limitation is that it won't work for a three-wire hookup, so if your trailer requires three wires, you'll need to look at the 3-wire version instead. If you've confirmed two wires, this pigtail is the direct replacement you're after.

WPS Trailer Light 3-Wire Pigtail 42-3080

WPS Trailer Light 3-Wire Pigtail 42-3080 Powersports Wiring Harness

This is the 3-wire version from WPS, also in new other condition and made in the United States. It's designed for a trailer light system that uses three wires, giving you the additional conductor that a three-wire setup needs. With the same price as the 2-wire version, it's the matching choice for any trailer that requires three connections. The trade-off is that it's not suitable for a two-wire setup, so if your trailer only uses two wires, the 2-wire pigtail is the better fit. For a three-wire trailer light connection, this is the one that lines up with your needs.

Final Choice by Use Case

Identify your trailer's light wiring first. If your connection has two wires, choose the WPS 2-Wire Pigtail (42-3081). If it has three wires, choose the WPS 3-Wire Pigtail (42-3080). The matching wire count is what makes your trailer lights work correctly.
