I picked up the boat today from the indoor storage. Bad timing because we had rain today. Also, I noticed that two of the pins in the light connector are on their last legs. Need to replace before I go anywhere else. The connector is a flat five-conductor. The truck takes a round plug from the trailer, but they are very expensive. Any opinions on whether I should replace it with same or jump up to the round plug?

To me the round 7 pin connectors are much more durable & better set up for retrofitting.

You can probably pick up either an adapter from the 9-pin round to the 5-pin flat connector at Wally world, or just pick up a new replacement plug there, cut off the bad plug and splice the new plug right to your existing wiring.

The current trailer connector is a flat 5 conductor plug. I have a 9-pin socket on the Tahoe, and have been using the adapter. I need to replace the 5-pin plug on the trailer. I think I will fit it with a 9-pin round plug. Much more robust--but big and ugly. (:-)

Is your round a round 5 or a round 7. I hard wired a round 7 on the boat trailer when I redid the wiring quite a while ago.

I would just buy a round connector and cut off the 5 flat. Hook up the wires and no more adapter needed.

I thought my round socket on the Tahoe was 9-pin. It is 7-pin. Sorry about that oversight.

If I put on a 7-pin plug on the trailer harness, the only time I'll need a 4 or 5-pin flat to 7-pin round socket adapter is if I pull someone else's trailer, or my utility trailer which is 4-pin (will fit a 5-pin plug.)

Definitely go with the 7-pin. In decades of towing, the worst I have needed to do with the 7-pin style connector is spray some WD-40 into it. The flat connectors have constantly needed attention to keep working.

Believe it or not, I have had similar experiences with flat connectors except this one time. Of course, the trailer is stored indoors year 'round. Since it has always been difficult to insert into the 7 to 5 pin adapter, I think this has been damaged since new. Because I am on a short timeline--have to tow it tomorrow-- and because it was easier to simply substitute in a flat plug, that's what I did.
