I can't remember which side of the socket to insert the probe but your probe looks way too thick and it should not have a tapered end. I'm pretty sure what you are using will just jam up before moving the locking tab.

 

Thanks Overboard, it looks a lot bigger in photo, also using a long thin piece of metal from wiper blade which is much better so yes I'm happy with the size and fit and point taken on the taper.

I just depinned almost every plug on the patrol and an isuzu dmax.
These are the easiest of them all. I filled down a small flat head screwdriver. The waterproof ones can be a bit tricky

Having the right shaped tool is the most important factor in the whole exercise.

 

Thanks Benny, I'll give the bottom photo a more determined go in the morning, will let you know.

 

Some plugs are also pull to seat, meaning you have to feed the bare wire through the plug, then put on the terminal and pull back to lock in. No way to pull them out backwards at all.
Just a thought and an option, i don't know that plug.

 

Dont force anything. They will slide out easy as if you do it right. For that plug you need to lift a little tab away from the terminal.
So in that bottom photo point the tool down into that hole then when you hit the tab lever it up gently.
Once you have done one you can get a good look in there and understand whats going on.

If you want to get new terminals to crimp on i highly recommend www.jaydeeautocables.com.au
They have a huge range of oem auto electrical stuff.

 

Thanks for the advice Guys but still unable to disconnect pins. Will take a trip to the wreckers and see if I can get hold of a harness and cut it at the terminal block with a bit of length so I only have to rejoin wires..cheers

 

The pick i made is less than 2mm wide and 1mm thick. This is too big for some connectors but its fine for this plug.
The part in the circle is the lock tab. That just needs to be lifted up and you can pull the terminal out.
Dont pull on the wire until you lift the tab the it should just slide straigt out

 

Thanks Benny...success...couldn't have done it without you.
Was still struggling until I turned my filed down screwdriver onto it's side and out she came, many thanks !

 

I now have the correct tool for this but prior to that my favourite tool was a ground down piece of hacksaw blade and a ground down $2.00 screwdriver. Both about 2mm wide.

My technique is to push the terminal forward with the wiring from behind to make sure there is no load at all on it and it can give a bit of clearance to the tang, then use the pick, then pull the wire out. It's a little awkward pushing the wire while holding the plug with the same hand but you get the hang of it. And I usually clean out the old grungy dielectric grease first too so I can see what is going on.
