Avalanche,
I spoke to Year One and was told they had stopped carrying the Spade terminal tool and the Steering column tool due to the vendor. Was unable to give me any further/helpful info. Searches were coming up empty.
I practiced on spare connectors that I have.
For the Female Spade Connector; I used a small narrow flathead screwdriver, (an extra, so didn't mind filing it so that it would fit into the center channel within the connector housing), also used one of my straight dental tools ( I got from my dentist about 15 years ago, which she cleaned in the autoclave for me, they are very handy and can get into tiny spaces- carbs, o-rings, etc. ). Both worked fine for me.
To Remove Female: From the wire side I slid the wire towards the connector housing then put the screwdriver into the front of the connector housing's shallow center channel ( just under the metal terminal) , I was then able to pull the wire back out from the connector housing (you may have to jiggle the wire a bit).
* If you are reinstalling the same connector (for example, after a repair) make sure you gently push the locking tab down just a bit ( on the metal terminal ) , so that it locks back into the connector's housing once reinstalled. *
To Remove Male Spade : I used Needle-nose pliers (bit longer than standard) and put pliers straight onto the metal spade terminal ( with metal spade terminal vertical within the jaws ) about mid way, with gentle pressure and was able to push the spade terminal free then pull out from the rear of the housing. * Gentle pressure, Not the death grip *
Hope this helps you along with your project.
