Pictures?

At least with VW harnesses I have great luck with Channelock neednose pliers, though my Knipex will do too.

 

Stuff like this is why i wish every car was wired with MOLEX connectors. Wish i had some usefull advise.

 

Do you have any pics? Pins usually just push in and click into place. Most connectors just have a little spring tab that needs to be depressed from the front of the connector (non wire side) and pulled out gently by the wire. I have used a single side of a cotter pin before. If the connectors are round, like many Europeans ones are, there's a thin walled cylinder that fits around the connector and depresses multiple spring tabs to allow removal. You may be able to remove these by depressing one tab at a time and tilting the wire the opposite way and doing this around the connector. Hope this makes sense. Look down the face of the plug and see if you can see the tabs.

 

They do actually make harness pin tools. Some are maker specific (i.e. Toyota/Lexus)
Best bet is to get new pins and a good crimper and repin as needed.

I apologize for not remembering the name of the place I used, but if you plan on doing an extensive amount of re-pinning on an automotive harness, you should definitely invest.

 

I just got this set. It has tools for most molex plugs..

Set, Terminal Tool, Soft Grip, 6 pcs.

 

Thanks for the save on that Joey
I had one years back that I purchased (SST from Toyota when I worked for them)
Good to know that Snap-On makes a nice set like that. It's guaranteed to be great quality.

 

No pics. I'm needing to add pins to a harness. This is on a AM General vehicle. Pretty much what you see on most radio harnesses. The pins are pretty much square, or U shaped. I'm trying to insert 2 large pins and 4 small ones but can't get them to slide in. I have placed pressure on them but don't want to force it too much.

 

Sometimes there are bars/clips/clamps/inserts that have to be removed before pins are inserted. See anything like that?

 

You can see where the harness plugs in. I wasn't able to get a clear picture of the connector since they are already installed and hard to access without removing the center console.

One of the connectors where 2 larger pins plug in the empty spaces. The other connector to the left 4 smaller pins plug in.

The 2 larger pins on the left, the 4 small pins on the right.

 

Overlooked the clips that held the pins in place. Silly me
