Question:

I am looking for an adaptor for magnetic trailer lights that havve a 4-ipin round plug. I want to be able to plug directly into my 2019 GMC denali which has flat trailer plug and a round plug. Is this something you have?

Expert Reply:

I do have a couple options for you, but there isn't an adapter to go from a male (trailer end) 4-pole round to a female (vehicle) 4-pole flat or even a 7-way.

So, you could either make your own adapter using part # PK11410 and # HM38138, if you do not want to modify the harness on your magnetic trailer lights, or you could simply replace the 4-pin round connector on them with part # HMC20031, which is going to be the most cost effective.
