Hey Ken, welcome back! The TowSmart 4-Way Flat Trailer Wiring Kit item # TS48RR is made of 18 gauge wire. These are a set of 4-way trailer and vehicle side 4-way connectors that have 12" of wire attached to each of them.

What kind of trailer do you have?

Thanks Jarred. I asked about the wire gauge because I want to use this product to re-wire an older tractor, not a trailer. It looks like this should work well for that purpose. A few of the wires on the tractor are a heavier gauge, like 14 ga. Do you offer any wired connectors in 14 (or 12) gauge? Ken

@Ken You're welcome! 18 gauge is pretty standard with 4-way connectors like item # TS48RR and for what you're doing will be sufficient. The voltage will still be enough with 18 gauge wire to power lights. What you can do is use the Quick Fix (TM) 4 Pole Flat Car and Trailer Ends item # 48195 and a couple feet of the 14 Gauge, 4 Conductor Jacketed Wire item # DW04923-1 to make one.

That's a very good question, we tend to be extra cautious and say to use 10 gauge wire because that would be more than enough. When you get into longer trailers that will end up using a lot of wire the heavier gauge wire becomes more necessary.…
