## Customer Reviews

### ⭐⭐⭐⭐⭐ Very happy with it -
*by A***R on 2 June 2026*

Great product

### ⭐⭐⭐⭐⭐ Good option
*by J***1 on 23 June 2026*

Perfect fit. I have a 26 palisade and needed to plug a 4 pin and this adapter works perfectly. Easy to install and seems to be good quality.

### ⭐⭐⭐⭐⭐ Simple, inexpensive fix
*by L***Y on 22 June 2026*

Bought a trailer and then realized the cord plug in system underneath was damaged after having electrical work done on the truck. This fixed the problem. It's a safe option vs rigging something togwther that may not be safe long term. Plugged 7 blade into truck, exposed 4 pin to pkug into trailer. Now ALL the lights work! We're legal. We have a 10 ft trailer so we're required to have lights and we should since all the equipment is there. This fixed our problem for less than $15 at the time of purchse. Store options were $45-60. All black, looks good (like it's factory), and works as described
