Clumsy me hooked the edge of my boot on a wire attached to the data link connector that plugs into the OBD connector and broke it clean. I’m perfectly capable of soldering a wire in to fix it, but I have a couple of questions. 1, are the wires that go to the data link connector 20 gauge? They seem mighty thin. And 2, does anybody know offhand what the secret to opening this connector is? I can pop the outer edges out with a fingernail, but all of the wires remain snug in the connector. What am I missing here? TIA.

Edit: am i supposed to pushed the pinned wires out through the front?

 

That connector is a Yazaki 7287-2047-30. To de-pin it, you pop the white piece, which is called a TPA (Terminal Position Assurance), out slightly to the unlock position. Then, through the little holes above (on the top row) or below (for the bottom row) you go in with a terminal removal tool, Yazaki 49YA000105, and lift the stop tab (for the upper row) or pull down (for the bottom row) and pull the terminal out the rear of the connector. Small gauge de-pinning tools are usually available from Amazon. I got a set with a plastic trim remover kit. A really small jewelers screwdriver can sometimes be used as well.

The wires are all 22 Ga.


The TPA is Item 2 below shown in its unlocked position. Just make sure that when you replace the terminals that they are installed in the correct orientation or they won't lock in properly.

 

THANK YOU! There is now way on Gods earth I’d have figured that out on my own!

 

You are welcome. Let me knoe if I can be any more help.

 

Hey 52 merc., does the extraction tool also work for pins 1 and 13? The larger outside two
TIA

Not according to the Yazaki catalogue. The 2.8 mmm terminals use a X39899-J374 tool.
I usually just use tools I have on hand like a jewelers screwdriver. I've always managed to find something that works.
