Trailer Connector on 1994 Ford F-250 Only has 12 Volt Power on the Center Pin

Question:

I have 12 V power on the center connector of the 6 prong connector coming from the truck, but no power on the rest of the connectors. It is a 1994 F250.

If it is really a 6-Way and not a 7-Way blade style trailer connector then the center pin being hot would indicate that particular pin is the 12 volt power circuit. But the other functions not working could mean that tow package wiring fuses and/or relays are missing or need to be replaced. Check the truck owners manual to find the locations of any and all fuses related to the tow package wiring.

If the wiring was added and is not factory then you will need to check the wiring connections and look for any damaged wires or missed connections. In 1994 the Ford F-250 would either have come with no trailer connector, a 4-Way flat connector, or a 7-Way RV style connector.

If it did not come with a factory trailer connector you can add a new one by first installing a 4-Way, # 118316. Then you can install a 6-Way using # ETBC6 or a 7-Way using # ETBC7. I have included some links ot the right that would help with this installation.
