Question:
Could you tell me the difference between these two products on your website? ZCI Circuit Protected Vehicle Wiring Harness w/ 4-Pole Flat Trailer Connector and Installation Kit - 119251 ZCI Circuit Protected Vehicle Wiring Harness w/ 4-Pole Flat Trailer Connector and Installation Kit - 119250KIT The latter is 20 bucks cheaper, but I cant find a clear difference otherwise. Thanks, Theo

Hey Theo,
The only difference between # 119251 and # 119250KIT is that the # 119250KIT comes with a circuit tester included. In my opinion, installation will be pretty difficult without the tester , and it happens to be the cheaper one. I recommend going with the # 119250KIT for your setup. Otherwise they are the same exact wiring harness, one has a tester one does not.
