Electrical Harness Clips/Brackets Removal

The wiring harness connecting the battery and fuse box to the starter motor, alternator, and ground are affixed in a couple places with clips or brackets marked with the number “15”. The forward of these two releases easily by squeezing a tab, but the clip farther back seems to be connected with a split plug. Is there a method to open this clip to release the cable, or free the mounting plug from its hole without destroying it?

 

The first clip, easy to remove-

-and the stubborn clip:

 

Surely anyone who has replaced this harness has had to confront these mounting clips.

 

I cant help on these exact clips unfortunately. But I have used WD-40 in the past to soak the release tabs down. Makes the plastic slippery enough and helps release rather than cracking or breaking.

That method works especially well if you can get a pair of needle nose pliers on the back side of the clip to release it from its mounting hole

 

Till I got the Tacoma is was just cable ties which was easy snip do what needed done new cable ties .

Any more side cutters are my go to for removing old plastic clips.

I had heard a heat gun is nice for getting the plastic soft to work with

I would rather cable tie a harness or cable to a bracket then be extracting broken bolts after the last one turned into a few thousand $$ in repairs.

 

Thanks for the tip, Blackbird- didn’t help here, but may well down the road.

Does anyone know the name of these parts? Would help to find instructions how to open them.
