Options for Towing a Trailer with 7-way with Vehicle with 4-Way

Question:

I have a trailer outfitted with brakes. However, we use it primarily with light loads and most of our vehicles are not equipped with 7 pin connectors. Can we splice a 4 pin male connector into our 7 pin trailer connector? Im hoping that by having two tails, we can connect to all of our vehicles.

Helpful Expert Reply:

If you do not plan on using the brakes of your trailer you can splice a 4-way into the 7-way wiring so that you could control the taillights of the trailer.

For that you could use the part # HM48110 to wire in the 4-way. Or you could just use a 7-way to 4-way adapter on the trailer like the part # 30717 and just tape up the extra wires that wouldn't be used.
