Double Wire Recommendation for Powering Trailer Wiring and 7-Way 12 Volt Circuit

Question

Question:

I installed Tekonsha T-one vehicle wiring Harness which has a hot lead to battery. I am planning to purchase Trailer Mount brake control Prodigy RF. I need run another power cable from 7 pole connector to the battery. I am wondering can I connect the power wire from 7 pole connector to the hot lead on T-one harness instead run a power from the battery under the front hood. Thank you very much!

You wouldn't want to use the same 12 volt power wire for the 7-way to install the Prodigy RF part # TK94FR and the 4-way kit you have as well. Your best option would be to use the part # 10-2-1. This is a double wire that's bonded together so it would be like running a single wire but you can then split either side of the ends of it for each circuit and you'd be set.

That's a very good question, we tend to be extra cautious and say to use 10 gauge wire because that would be more than enough. When you get into longer trailers that will end up using a lot of wire the heavier gauge wire becomes more necessary.…
