Blinking third brake light

Check this out. I just bought one and will attempt to install at the BCM. This units senses the actual braking deceleration, and changes the flash rate depending on how hard you are braking.

Side Bar:
Recall the when I bought my 1st Vette, an 1988. As with all 5, ordered with the options I wanted. Dealer sales manager, who I dealt with directly, said I'll have to ask for $2000 none refundable down because if it comes in and you don't want it for whatever reason I will have a hard time selling with a standard shift! Had no problem with the $2000 as I had just sold enough appreciated stock to pay for it, several weeks before the market crash that year! Good timing!
Had a product manager who had an '85 Vette and when he looked inside mine he said jokingly, 'To cheap to buy an automatic!' I just chuckled and didn't bother to tell him that year the Doug Nash 4 speed with an electrically operated two speed overdrive attached cost the same as an automatic! He was too young to understand!
That was an interesting trans. My 2nd 7 speed! You activated the overdrive with a button on top of the shift lever. You could split shift and go from 1st, 1st OD, 2nd, 2nd OD and so on. Could not activate in 1st so only 7 not 8 gears!
My 1st 7 speed with a twin stick Dodge Colt Turbo! Bought that when we needed good gas mileage as we had been through buying gas every other day! Could not go from CT to LaGuardia and back on even a full tank of gas in my CJ5 V8, header etc. I traveled a lot and a number of times stayed out of town because I couldn't get gas the day I was supposed to return! It actually had 8 gears if you split shift as you could use LOW in 1st, but when you split shift two ratio's were the same so only 7 speeds. Great fun car, went +1 with 14 inch tires and Pirelli P7's as I recall and other mods. Fit it's name, it was a "Pocket Rocket" for the time!

This should be easy to do on the C7, without taking the rear bumper off, as the center stoplight is fed thru a separate wire, from the BCM. The flasher circuit can be added next to the BCM, located in the toe-kick area in the passenger side footwell. BCM connector X4, pin 11 drives the center stoplight. X4 is the black connector between the green and brown connectors. Pin 11 should be a violet wire with a white stripe.

I emailed, we'll see if they have any info.
Wish I had saved that info from a rep for a company making these. There was little detail but as I recall he removed the right taillight Bezel, reached in the space, pulled out a wire(s) and spliced in a module.
We'll see what info I get. With well over 100,000 C7 sold don't see they really need any connectors just some splice wire connectors and perhaps clip a wire. However it you have to remove the bumper to access, that would be a problem and make many sales unlikely.
Surprised with some folks removing the bumper for various reasons no one has reported installing a blinker.

See post #7, there is no need to remove the bumper cover, the wire you need to splice into is easily accessable in the passenger footwell, at the BCM.
That is as much detail as I recall and it was very sketchy.
See pic 11 of the below post for instructions to access the BCM.

As you note in another post sounds it's easier to take off the bumper!

When installing you have to cut the wires and then splice in the unit so in effect you are extending the wires. I could just not get them out far enough to comfortably have enough to make the cut.

I suspect that you can also find the correct wire (Violet with white stripe) for the center stop-light) in the harness that is accessable under the cargo area carpet, in the shallow well where the rear fusebox (and some electronics modules) are located. I believe that the center stop light wire passes thru that area, thru the main chassis harness, on its way to the BCM.

OEM Connector: HIT2PB-26-D-K
Service Connector: 19151263
Description: 26 way F 0.64, 2.8 Series (BK)
Mouser does not seem to have it. They do have the pins however.
I found one place in the Netherlands that seemed to have the entire connector (6) harness for 360 Euros
I see some hits for GM 19151263 - about $50. No picture. I assume it is just one side and without Mouser's references, I don't know how to find the opposite to make a plug-and-play for the BCM X4 connector. I'll ask TrunkMonkey and see if they can trace it down.
Looks like a splice is the only alternative. Unless someone can find this?

My Google-foo turned up the following: https://nexelec.com/JST-HIT2PB26DK/. No picture, $1.29.
But doing some searching looks like this is the documentation:
http://www.jst-mfg.com/product/pdf/eng/eHIT.pdf
So the other end looks like something that goes to a PC board like on the BCM board itself? It would be better if there were a standalone male connector available. I guess one could chop it up into individual male connectors.
As you can see, I am no electrical engineer...

Has anyone actually verified that Pin 11 on BCM connector X4 works only the 3rd brake light and not all three brake lights?
Has anyone found the Voilet with white stripe wire for the middle tail light under the cargo area carpet?

Now that the Florida Inferno has mitigated, I finally got to install this. Confirmed: Pin 11 on BCM connector X4 (the black connector on the BCM) works only the 3rd brake light.
I used the Geezer's instructions for access to the BCM. https://www.corvetteforum.com/forums...tallation.html The black wire on the corner of that same connector is a convenient ground. Used three Posi-taps connectors.

These are 2 of the many pics in that post. What wires are we cutting/tapping to install?
Only plugs I see with 11 connectors. If it is one of these-what number am I stripping the wires in the bundle (and I can find a black wire to tap for a ground and verify it is in fact a ground) what is the color of the one I cut and splice in the flashing module. Assume I cut as I installed a module in my C6 and when I buy one for ~$15 it will have a wiring diagram. Just want to be sure I cut the right one!

Thanks BUT, still don't know for sure what plug or what wires?

Neither of those two plugs. Those are the Navtool harness.
In the background, you see the BCM. There are 7 connectors on the bottom of the BCM. The connector you want is the black conector, Pin 11 on BCM connector X4 (the black connector on the BCM). That black connector is the 4th one from the left.
Here is the pin out. Please ignore the arrow I drew on the picture which is for something else. You want PIN 11.

However I still had a question from your breakdown of pin numbers as I thought where you had an arrow was where I was to connect! But that said it was the Right Front Turn Signal Lamp Signal!
How I believe I answered the question by finding another diagram!
Could you check out the top pic and see if I am stating the connection properly?
Is this the correct way to connect?
This is the pug as you note.
My confusion was the arrow on this table, which I see now had nothing to do with what I was supposed to be looking at!

Really do appreciate the help from folks who can read these "new" electrical diagrams! Realize some stuff today is just signals on a buss!
I have to chuckle as you'd not believe this 75 year old wired my Street Rod from scratch ~17 years ago making all my own electrical diagrams! However used what is easy for me to understand! If the wires are not touching you use a loop!
I was surprised myself that the car started and all lights, stereo, gauges, electrical door and windows, etc etc worked from Day 1! Have had almost no issues!

If the above diagram in post 36 is accurate adding a module is not hard, have to look at the links on how to get to the BCM (body control module.)
Just checked, there is one module that many folks are selling on ebay and some he same one on Amazon! Found one of those for <$3! Most range from $7 to $15 for the same one! Scary how someone can ship from China free and charge only $3! Unfortunately many of the others are getting from the same source and selling for ~$15 with US delivery! I could not find any type from anyone that made me feel confident it was any better! Once they come from China at crazy low prices US manufactures give up! Can't blame them!
Side Bar:
I recently bought a Brake fluid water check for under $3 direct from China. Amazon price was $10 to $12 for the same one, same pic! I bought for a fun check of my Brake (Clutch) fluid as I am about to do a Ranger Method flush. It came in a sealed plastic display package that had to be cut open. All info on the colored sheet is in English. Hard to understand how something that can't be in high demand can sell so cheap! China gives them fee postage! Says so on the envelop it came in.
