When installing the 7-way Upgrade Kit for Wireless Trailer Brake Controllers # ETBC7L you do not need to disconnect the battery due to only one wire (The black power wire) getting connected to the battery.

I recommend connecting the 4-way connector on your vehicle to the 4-way connector on the # ETBC7L and then run the power wire to the positive terminal of the battery.

Depending on the trailer hitch receiver you choose for your vehicle you may need a no-drill mounting bracket # 18136.

I included videos of the products mentioned for you to take a look at.

Hey Antoine, so the two kits you mentioned are actually really similar and honestly I would go with the part #ETBC7 if I were you. The #ETBC7L is basically the same thing minus a couple wires and breakers so you may as well get the kit that has…
