Question:
Looking to see if you sell a trailer harness that has the standard 4way flat on one end near coupler and a 4pin square sae on the other end. That connects at the back of the tongue. I can send a picture

Hey John,
It unfortunately looks like we don't offer a 4-flat to 4-square adapter or even just the square 4-pole connector to make one with. I wasn't seeing the exact adapter you're needing but you can still purchase a 4-pole square connector elsewhere and splice it into a 4-pole pigtail # HM47115. The # HM47115 comes with both the vehicle and trailer end connectors so you can cut off whichever isn't needed. You'll want to use some heat shrink butt connectors # DW05744-10 when splicing together your connections for a waterproof seal.

Hey John, did the 4-pole pigtail and heat shrink connectors work out for your trailer harness setup? Knowing how that splice turned out could really help others trying to make the same connection.
