I found them over here at a cost of £129.99 against your $40, searched again and found them at £42, rip off Britain

That picture was from an old connector. I just used that to illustrate how a sewing needle or a safety pin would easily slide down and not damage anything.

A pack of 50 safety pins of various sizes costs a whopping $1.89 in beaver bucks-!!

July 2013, 2010 Buick Lucerne, $200 diag charge, $100 labor charge, $600 suspesnsion pump/valve replaced
April 20, 2015 same car gets valve replaced again. Only $175diag this time , still $700 install
April 21, 2015 same car is in my bay because new valve doesnt work again.... $100 diag, $50 wire repair.

No power to valve, wire rotted off inside insulation where original tech pierced wire to test valve circuits Which was just pure laziness as a test light does the job with ZERO damage.

There was some sort of goo(dime store rtv?) attempting to cover hole in insulation and harness was properly taped up and showed no signs of moisture inside EXCEPT where the wire was pierced.

I have tried the "liquid electrical tape" AND THAT STUFF SUCKS-!!!.

Up here corrosion is rampant and any kind of "piercing" WILL end up with a BAD CIRCUIT-!!!!!!!!!

It's not IF it corrodes....it's WHEN will it corrode-!!!

DO NOT PIERCE WIRES-!!!! It's a very poor, and NOT a professional technique-!!!

I can not count the number of times I have had to repair the results of this practice of "piercing wires" and it goes all the way back to the 1970's-!!!

Again, and again, and again it shows up later. Since the 1970's-!!! GEEZES-!!! Don't people EVER learn-???? No wonder this trade gets a bad name when people keep making that same mistake.....

Default Something different

I know this violates the "Do Not Disturb the Connector" rule but if you need to monitor a circuit without damage this will work. Just strip a 12 gauge (or wire of your choice) and insert it between the two halves of the connector for the circuit in question.

On larger terminal wire connectors like that you can also easily back probe with a T-pin and not damage anything as well as placing a single "thin" strand of wire placed inside the female terminal and shoving the male side in, might not damage anything, but to do it with a tiny gauge terminal connectors of PCM would spread and damage the terminals .
