Question:
Let me start by saying Im confidently comfortable when it comes to a lot of things, but have little or no experience when it comes to auto wiring. That said, I have a 2012 Jeep Wrangler Unlimited w/ tow package. The package includes a 4 pin flat plug next to the hitch. We are purchasing a Tear Trailer that requires a 7 pin connection at the hitch in order to charge the battery on the trailer. The trailer dealer wants $300 to install an adapter. Considering it looks like the part costs about $25, I think that is a bit steep. Can you tell me what part is needed to accomplish the task? And, how difficult would it be to install the additional wiring needed?

Expert Reply:
If your 2012 Jeep Wrangler Unlimited came with a 4-Way you will need to use 4 and 7 way installation kit # ETBC7. This is a hardwire installation but it does come with everything you will need for the installation. I have included some links that will explain the ETBC7 installation for you.
If the trailer also has electric brakes you will need a brake controller to operate them. The ETBC7 comes with the wiring needed to install a brake controller but the controller itself is sold separately. I recommend the P2 # 90885. It is easy to set up, easy to use, and it is reliable.
