  • Perfect fit
I recently bought a new enclosed trailer and the place I bought it from installed an electric brake system in the van that required a larger 7 pin connector for the electric brake unit. It required taking the old trailer connector out and replacing it with the larger connector which left me without the ability to use my small open trailer electric system. Then I found this 7 pin to 4/5 pin flat blade adapter that works easily and fits perfectly in the new trailer receiver on my van without having to cut into the wiring harness or mount another receiver on the rear bumper of my van. Just plug it in and connect your trailer wire to it and you’re done. Very reasonably priced and made well. ... show more

  • Works great
I bought one of these years ago that finally broke and I had to replace it, I was surprised at the price of this but took a chance. It's exactly like my old one that I paid a LOT more for, and it works fantastic. I haul a few different trailers and use three different vehicles, so I am constantly changing this from vehicle to vehicle. It's very handy to have on hand if you haul anything at all. ... show more

  • Does the job
This is used to convert from a Nissan Armada factory tow package. The 1968 Aristocrat trailer is a 4 pin and worked perfectly after replacing the earth on the trailer. Interestingly, it makes a loud sound when the vehicle is in reverse - not sure if this is a feature of the Armada or the device interacting with the tow package - it's annoying and distracting when under pressure backing into tight spots. Nonetheless the device is a secure fit into the vehicle receptacle and with the two options for trailer conversion it is definitely recommended. ... show more

  • Well built and good looking
This is a nice combo unit. I occasionally pull a trailer with a 5 ping plug and this solves the problem of having 2 adapters. It seems well-Built and it looks good I like that it has terminal covers. Works well
