Question:

I want a connector that brackets to my vehicle, that has 4 wire flat and 7 wire blade connections, and I want to be able to use both at same time. I see some choices, but I do not see any wire pigtails that can be wired to my vehicle wires. When i put in my vehicle, your website wrongly assumes I have a factory tow package, and website also told the previous web help person that my van has factory tow package.

Hi Maurice; since you don't have the factory tow package or any trailer wiring you need to start by adding the Hopkins Plug-In Simple Vehicle Wiring Harness # 31345. Normally I would recommend the Curt T-Connector Vehicle Wiring Harness # 55540 but it doesn't have a powered converter. Since you plan to use the 4-way and 7-way simultaneously you want the converter to help reduce strain on the vehicle wiring.

You will also need the Universal Installation Kit for Trailer Brake Controller # ETBC7. This comes with everything you need to upgrade the 4-way to a 7-way. The adapter maintains the 4-way connection so you will be able to use both at the same time. However, you still need to be careful to not overload the circuit.

I attached some installation videos below for your reference.
