Question:
I need to fix my truck wiring for the 7-pole connector on the truck. The harness to the truck wiring needs to be replaced. It doesnt look like the typcial T-harness you prescribe for the 1991 F250 will work since its a 7-pole trailer connector. What do you suggest?

Expert Reply:
The 118316 T-One connector is the correct replacement harness for the 1991 F-250 and should replace the 4 way connector on your pickup as long as no modifications have been made. If there is some other connection you could send me a picture or let me know what it is and where it is connected and I will try to help you out.If the T connector will work you can use the 4 pole to 7 pole adapter, part number 37185, to complete the rewire of your 7-way connector. If you do not already have existing wiring for the 7-way connector you can use the ETBC7 wiring kit to wire your the 7-way connection.If you just need to cut off the current 7-way connector and replace it you can use the 7-Way Plastic Car End, part number PK12707, to replace the vehicle side connector.
