My truck has the connector that the truck bed plugs into but right next to it are two others. One is heavier and seems to have the trailer brake wire and possibly trailer battery charge and the other has smaller wires that do who knows what. I presume there was a trailer brake connector available once upon a time like my 97 which is of course different. I wonder what the part number was so I can search for one?

 

Really going to need some picture to see what you're talking about.

 

Maybe these diagrams will help, they are for a 1990 but I think the 1989 is the same.

Those diagrams are very helpful and they match pretty much with what wire colors I have.

I was asking more specifically about C407 and C417 which are two connectors right near the rear bumper which probably were meant to have the trailer connector adapter installed in them. My 1997 has this but the Ford connectors are different.

If there is any way to find the Ford part number for this connector that would be great, then I can do a search on ebay or something.

Otherwise I can just cut the connectors off as they are but I'd rather not do that. Maybe I can find out what type of connectors they are and order matching shells and pins but that would be a lot of work.

The link is helpful, but near as I can tell, it references stuff in the mid-1990s.

The connector C407 with the heavier wires (brakes, stop lamps, battery and ground) might be the same as used on the mid 90s like my 97 which is sitting nearby but seems to have different wire colors and stop lamps may not have been included any more.

On the 87, the connector C417 seems to have changed to the type found in C417 with the larger pins on the 97 truck, with backup, tail/marker, left and right lamps. On the 89, it is a smaller connector with smaller pins.

The part numbers F4TB-14A464-AT and F6TZ-13A576-BA seem to reference the newer style. I should think the one that would have been made for this truck would have had a part number beginning with E for the 1980s.

Ideas?

 

Hey, look what I just found in the front of the truck. It recently had the beds changed around which is why I was trying to figure all this out.

For reference if anybody is trying to figure this out, the PN is E9TB AA 13A576. Is there a more recent part number that supersedes that?

Thanks for all the great help.
