This may be easy for some, but if you've never depinned a connector before, it might be overwhelming because you're afraid of messing up your harness. After this guide, you'll be confident enough to jump right in and depin the connector without cutting any wires. The benefit of this strategy is that you can always repin your connector as if nothing ever happened, whether you decide to remove the PowerFC or when it comes time to sell your harness in the future, it will retain its value since it's not permanently modified. Before we dive into Step 1, let's review a page from the most famous guide on installing your PowerFC by Dale Clark.



In my example, we'll work on the 'EGR Solenoid,' which is identified by the Blue/Yellow wire.


Then in the next image, I'm using a pocket screwdriver to gently pull back the retaining clip on the connector or locking tab. This yellow connector has two small pegs on each side that secure the clip in place.


Once you get the retaining clip up with the screwdriver, it will flip up, exposing the back of the pins. This action gives us enough clearance to remove the connector. However, we're not finished yet.


Now you need a 'Terminal Pin Removal Tool'. I bent mine intentionally so I can look down the hole in the pin to see what I'm doing. There are different sizes; use whichever one you are comfortable with.


Now I'll show you what the retaining pin looks like from the front and where you need to position your tool.





Here is the pin with the tool inserted; notice how the barb is now pushed upward.


Here's a second image at a different angle.


Finally, you're ready to remove the terminal from the back, but it can be a bit tricky since one hand is holding the connector while the other is pulling up on the plastic barb. What I do is use my pocket screwdriver and place it beneath the wire I'm removing. With the same hand that's holding the connector, I also hold the screwdriver, tilting it back while simultaneously having the plastic barb pushed up with the terminal pin removal tool.


Here's the terminal removed—congratulations! Now, just three more to go!


When you are done, this is what it will look like.


That wraps it up. Now, use shrink tubing over the bare terminals to prevent accidental shorts. Take your time—the hardest part is pulling the wire out while holding up the plastic barb, especially when you're leaning under the dash in the car. I had a good opportunity to take clear pictures while doing this outside the car, but I've also managed this inside the car; it's definitely possible. Good luck!
