Question:

What is the wire gauge for this part? Do you have any 25’ wishbone wiring harnesses of 16 gauge or larger?

Expert Reply:

The Optronics 4-Way Wishbone Trailer Wiring Harness # A25W2GWB that you referenced has 18 gauge wire for the ground and 20 gauge wire for all of the lighting functions. I check with all of the other wishbone harnesses that we have and they all use similar gauge wiring none of which is 16 gauge.

For 16 gauge wiring you can use the Deka Bonded 4 Wire # 16-4B-1 which is sold by the foot. I recommend using heat shrink butt connectors like part # DW05744-10 and the Quick-Fix Replacement 4-Way Flat Trailer Connector # HM48192 for your 4-Way flat connector. If you need extra 16 gauge wiring then you can find single wire as part # 16-1-1 on our site which is also sold by the foot.
