@TJBaker57 ... have a care with becoming too enthusiastic with your "whittling' down of any connectors, as having them fit more snugly rather than less means that the VCI Lock Down Handle will NOT accidentally loosen enough to break the Connector from the Main Logic Board and end up 'Lunching" your PASS-THRU or ordinary Reads-Writes to and from the In-Dwelling PCMCIA Card. I agree that there are some issues with the very close tolerances for the DLC and Locking Connectors... but THIS device does not cost the $4,000.00 that the GM OEM would be for the sake of not having the slightest of these very negotiable imperfections. You are likely to do more harm than good if you focus on 'adjusting' things to fit that may indeed loosen up in time if given too much leeway. Don't frequently R&R the PCMCIA Card for the very same reasons.

But... as soon as you have the opportunity to hook everything up to your Full Sized Truck and begin to delve into the problems and solutions that are NOT as obvious as some of these minor defects (if they really are such)... you will forget all about these issues. I never took the time to bother with comparing what the Exterior Component Model Numbers were in the way of not being a match to the OEM Numbers because the only thing that matters is that the 16 PIN DLC... fits inside the Female Receptacle... and allows this Knock-Off Scanner to perform with equal aplomb versus the GM OEM Tech2 Scanner. Of course THIS is really all that matters.

@Chickenhawk ... In the case of labeling problem... I agree that without having specific instructions as to where these labels get placed... without carefully...partially peeling the backings off of the Main Vetronix "GYMKO" and CANDi Device Labels... you would never know that they are actually fitted with partially opaque 'windows' that will require some very dexterous phalangeal gymnastics to carefully place the non-sticking, numeric sub-labeling underneath the right positions as you very carefully place the leading edge of the Main Label inside of the slightly submerged plastic outlines of the outer cases. Then VERY SLOWLY guide the right angled edges into place so that you do not mis-align any of them. If you sense that things are getting misguided... STOP.... and then carefully peel the label back off...and start very carefully....all over again. If you get impatient...and "The Lil Woman" catches a glimpse of your errant work... she'll think you were 'Drunk as Davey's Sow' when you applied them... and you'll never hear the end of it! :>)

My suggestion is that if you begin with the very top face of the "GYMKO" Scanner just above the Blue Screen and put into place that Narrow "GM" Logo Appliqué Label as Practice in finding out just how very careful you will need to be to accomplish this otherwise useless task... You will know exactly how much of a PITA, Detail Conscious Process this will involve. I have taken some close-up digital images of everything that requires labels to show you exactly where to 'sneak' in the sub-numbering... under the narrow opaque windows. If necessary... Use a bit of Transparent Scotch Tape to hold the sub-labels in place under each of the 'windows' for each outer label.

Apparently... This odd requirement is actually something the Chinese insisted upon adopting in order to emulate every aspect of the GM OEM Tech2 as closely as possible. This is probably because the GM OEM Flavors DID have these peculiar, non-destructive labels arranged to durably last in the harsh and repetitive use environment of their Dealership Repair Bays. Please note that the images of the Stick-On GM OEM Keypad involves me showing an EXTRA one that I purchased for only $10.00 with Free S&H just to have on hand and to use as an example to show @Reprise that his slightly damaged REAL OEM GM TECH2 Keypad can be easily re-placed after a careful casement disassembly and with using a a Heat Gun to loosen the Strong Adhesive to pull off the Old Keypad... re-insert the Dual Ribbon Cable through the Top Cover and set the New Keypad down with the same caution needed for applying these absurd labels.... and put it all back together afterwards.

One last suggestion worth mentioning on the Un-Boxing for you both... Peel the Left and Right Velcro 'safety belt' Handles loose... they were installed BACKWARDS in the China Assembly Plant. Slide them right back through the Case Pins IN REVERSE ...with the Soft Leather backing facing towards the back of your hands when using them to maintain a grip on this rare and important tool. If you try to use them right out of the Black Case (or Box)... The Male Plastic Velcro "Toothy" side will rip into your flesh like ice climbing crampons digging into a rock crevice.

Well currently the only way I can connect my DLC cable to the base unit is to engage the right side at about a 20 degree angle, rocking it gently to engage the pins, then engage the screw a couple of turns. Then rock the cable around to the left pulling against that right side screw until I can force it against the VCI latch enough to engage the left side screw and use that screw to draw it in tight, tightening the right screw as well. I don't see this as a good long term solution. I cannot connect it squarely from the get-go as the contact with the VCI latch forces the D-shell of the DLC cable too far to the right. For the time being I'll leaving the cable connected.

I cut the cable end off with a box cutter so I could correctly 'latch' the card inside the TECH 2. No other way I could see around it. Stupid design in the first place.

I honestly agree that this 'edged weapon' tactic will work to relieve the problem... but before you resort to doing so... Please remove the DLC Cable first AND Unlatch and Remove the VCI Module and then look down inside of the "GYMKO" innards for any post-manufacturing detritus or debris that might be jamming in between the card insert contacts and the VCI Module. Also... with the VCI device still removed.... cycle the Locking Latch back and forth a few times and listen-look for anything mechanical that might be loosened or broken internally. Check out that 'sinusoidal groove' that the latch mechanism has for any broken pieces of Plastic stuck inside. Then... Re-Insert the VCI... Latch it tightly... and then try to attach the DLC Connector once again and see if anything in contact has gotten any easier ...right there in between them.

Phew! Thanks! I now have the labels applied! It gives me a great feeling of satisfaction knowing that MY unit was actually built in the U.S. by Vektronix, and if I ever need help with my unit, Vektronix is just a 1-800 phone call away.

@Chickenhawk… all sarcasm aside, if you please… I re-read your post raising the other unanswered question about “The RS-232 NULL MODEM” and the RJ-45 Flat Ribbon Cable. My description of what this device actually is is better explained here:

Tan RJ-45 to DB-9 Modular Adapter

https://www.showmecables.com/db9-male-rj45-female-modular-adapter-kit

I pulled these components out of the “GYMKO” Case and took some more detailed images of them. These items might seem like the most trivial of all the “GYMKO” Kit Sub-Components in your Kit… but don’t be fooled. If the Tan RJ-45 to DB-9 Modular Adapter connection to the Laptop Computer is not well secured or casually installed… or if the two Male Plug ends of the RJ-45 Flat Silver Cable (4 Pair Twisted Wires) have not been “exercised” a few times to ensure that the (8) 12K Gold Plated Spring Wires of their Female RS-232 points ARE DEFINITELY in solid contact with each other… if they break solid connections at the S/S Port of the “GYMKO” Scanner at any time during their transceiver actions between each other… you could wind up “Bricking” your PCM (or other sub-modules during re-programming) during TIS2000 SPS PASS-THRU activities … or perhaps even ruin someone else’s if the proper attention is not paid to these seemingly minor details:

I realize this Thread is long past its "Use By ..." Date... but with the pending political uproar over the Tariffs pending versus the Chinese... I would once again urge everyone who even imagines that some day ...some time in the Future...they will need and use the "GYMKO" Kit while in possession of a wide range of GM Products to POUNCE on this Deal before the prices get Jacked Up. Right now... the offer remains at $330.00 with Free S&H and proven early arrival times.

Please... Think carefully of what you could be doing for yourself... and keep checking these two Links and consider what you are doing if you imagine getting some other Generic Scanner and make the mistake of spending damned near the same amount of Money... and passing on the One Device possessing Ten Times The Consequences of Performance and Utility of any other for the same price:

Also... I spied something worth pointing out in regards to the above discussion on the "GYMKO" Labels that in spite of their otherwise less than useless utility in the performance of the GM Clone Scanner... there IS one piece of very valuable information for those exploring the use of the "GYMKO" Scanner for any Bench Top Work where an External, Adjustable (Voltage AND Amperage) Power Supply is being used to power up both the Clone Scanner and say.... a PCM ....or a BCM. If you look closely at the bottom left hand corner of the Vetronix appliqué Back Label... you will see that the Voltage/Amperage ratings are 12VDC @ 1 Amp:
