16-way Harness Connector; How to remove wires / terminals from block?

Hi all,

Regarding the 16-way electrical connectors that are found in late-model YJ's (pictured below): how does one pull a wire (or 'terminal') from the block? (Is 'terminal the right word?)

I'm nearly complete with my 4.0 swap, but there are some mis-matches between the "new" '94 4.0 engine harness, and my existing '95 2.5 body harness.

I've got the beast running perfectly but I'd like to tidy the wiring a bit. I'll start by pulling unnecessary AC and ABS wiring.

I can't figure out how to release wires/terminals from the 16-way connectors.





Cheers,

Alex

I can't walk you through it personally, but if you google "Jeepforum jeephammer" his wiring threads could be of some use for you.

Yes they are terminals.

Adopt your pets. Don't shop for them.

The red surround pops off. Use a small jewelers screwdriver or more manly somilarly sized tool. Then the innards can be pushed out.

Thanks for the tips. I got halfway - photos below.

I was able to remove the red surround on one of the connector halves.

Next I pulled out one of the circular gasket rings sealing a wire into the connector block.

Then I tried pulling on the wire, and no go. How do I release the terminal from the block? Cheers.

Look down inside the connector at the pins. You will see a little plastic tab that pushes in on the pin to hold it in place. All you need to do is push that tab out. Use a pin to push it.

Take a look at youtube for connector pin removal or extraction.

Ditto, hence the small pointy, jewelers dainty manly tool requirement. Ruin one you dont want and then treat the rest with respect!

I know this is an old thread but sure would like to see any video link showing how to remove pins from the male side of this connector.

Thanks

No video link, but here is an example of one type:
https://www.waytekwire.com/item/3203...ose-Terminal-/

Notice the 'tab' sticking out below the terminal? That is what locks into the 'block' on that type of terminal. Use a small screwdriver or ?? to press the tab in and it will slide out. Every block I have worked on had an opening where that tab could be reached through.

The other type, (can't find a pic) has a small square 'window' on the backside of the terminal, the 'lock' is a small plastic tab on the block itself, these always have a small area that you can reach through to release them.

Seriously, once you see what they look like 'outside' it's pretty easy to get them out. They do make a tool to remove them easily, but unless you plan to do hundreds of the, it's not worth buying.

Edit: Push in on the terminal from the wire side to reduce the pressure on the lock tab with either style.

OK Thanks

Finally figured it out, you don't want to push anything into the lock that will mess up the protruding lip on the connector lock. I used a hard needle from my upholstery sewing machine, reach into the connector , catch the lip and pull the lock away from the pin.

Attached a "crude" drawing...hopefully it makes sense.
