Installed this taillight trailer light converter on my 2012 Prius v

I wasn't happy after checking all those etrailer videos with the direct plug-in kits.

They cost twice as much or more that a standard powered converter. And four extra bulky plugs and all of the extra "rats nest" wire turned me off.

So, I purchased this one from Amazon that works perfectly.

There was not enough room around the mini LED brake-running light connectors to used the supplied insulation displacement connectors. So, I used the newer 3M developed "flag" type insulation displacement connectors that accept 1/4 inch spade connectors crimped on securely to the wire ends.

I installed the brake, running and left turn signal wires to the left tail light and the right turn signal to the right tail light.
