Review: Plug and play, just add screws to secure it. - I should have just gotten one of these adapters from the beginning, instead of doing a custom wiring job on my truck to add in the 7 round receptacle. Only downside is that the cables coming off the ends are super short, so you'll want to get a small 4 pin extension cable if you're bolting this to the trailer like I did.
Review: Plug and Play -love how Simple it is. - Reviewing few things at once. Love how simple and Plug n Play it is. Wireless Lights Connect Instantly within 2-3 seconds—-and Never drip signal—Looove it. The Euro to US converter just works Perfectly 7 to 7 pin and 4 pin US to 7 pin Euro—works as well Perfectly. Im using Test Box to simulate Trailer -everything came in just wana shoot video quickly before i forget...
