Disassembling harness side trailer plug connector

I have a broken lock tab on the chassis side of the trailer plug receptical connector. I have been able to get the rear cover and rubber seal out, but the face side blue locking piece is giving me grief. I was able to find a used connector to replace the broken one once I can get it apart. Most connectors usually come apart quite readily, but this is the first time I have tried to do this particular style of connector. Nothing is wrong with my trailer wiring and I would like to be able to reuse it in the replacement connector. Thanks in advance for any help you may be able to provide.

Any chance you could upload a pic?

I think I know what your talking about. If you have some thin needle nose pliers you can use those to work the inner blue locking tab out of the plug. Tweezers will also work.

Hope this helps.

I tried using a pair of surgical forceps on the indicated points, but was still having no luck. Getting a little frustrated I went to the truck and took that connector out and was working on it on the rear bumper to see if something was different. Tried the forceps on it as well and it didnt want to work, but with the lock tab missing there was easy access to the inner edge of the blue lock piece. Put the connector face down on the bumper, placed a small flat blade screwdriver on the edge of the exposed blue lock and bumped the handle with my hand and it popped right off. Could now see that there are 4 lock arms holding it in place and went back to the replacement connector. Took a 1/8 punch gave it a tap with a small hammer and it came off with a few taps. Success at last!!!! Depinned both connectors, cleaned up the replacement, used dielectric grease and reassembled the truck end. Everything went well. Thank you Litner for your help and it did lead me to renewed ways to attack the issue.😀

Disassembling harness side trailer plug connector

I need to replace the same plug pictured above on the chassis wiring harness to trailer plug receptacle due to a broken clip.

Are there any parts gurus out there that know a part number for a replacement plug?

I’ve disassembled lots of these. Get a pair of needle nose and grab the outside of the blue piece on each side, longways if that makes sense. It’ll pop out and that’s the best way I’ve found or else you start mangling it.

Doesn't the whole connector and harness come out as one piece about a foot long to the harness above. I think the whole thing is easily available and replaceable. The short trailer harness connects the plug to the main harness by the frame.

Thank you for the part number.

I went to the local stealership and started with part number 05017114AA.

The parts guy was able to cross reference that part number and my 2004.5 truck with part number 82209771AB. The later part number was $10 cheaper than the former and also came with a new 7 pin trailer socket and mounting hardware. I went with the cheaper option.

A few beers and hours later I had cut out the inherited (purchased) mess, soldered the new plug/harness into the existing chassis harness, and applied marine grade heat shrink to the splices.

**public service announcement: please do not use the quick splice type connectors because they compromise the insulation/jacket of the the conductor and irreversible oxidation ensues**

Thanks to you that take the time to answer the questions asked on this forum.
