When you tap the RV mirror, which way do you route the wires - up, down, left or right? I have seen the videos but can't tell the orientation of the L shaped leads.

 

I actually don't remember but think I had to go towards windshield.

 

i did up , using red and black/white wire.

 

The wires go up Blendmount video

Thank you, guys.

I have been waiting to install mine until my driver's side map light gets fixed, so we don't get accused of the mirror tap messing the light up.

The part finally came in, so I want to make sure this goes as smoothly as possible.

One more thing. Is there a slot or hole that the wires can exit the mirror through or are they just pinched between the cover and the mirror?

 

Video posted earlier shows the wires are "pinched."

 

There's a spot on top where the wires come out. Here's a tip when you go to do the job put a cushion or pillow in the passenger seat and a towel or blanket on the dash. Kneel in the seat and lay on the dash to do the work. Takes like 2 minutes to do the job but figuring out how to get there took me a few tries to find a comfortable position where I could work and see what I was doing.

it’s a total pain in the *** if you’re over 6’…..lll

 

this guy makes it look like a piece of cake, it’s not a piece of cake unless you’ve got miniature fingers and are 4 feet,10…..lol

 

I'm 5'9" and was quite comfortable doing the job once I figured out how to position my body... and it was a piece of pie.

If the tap is done wrong the driver side mirror will turn blue

 

One thing I hate about most How To video's is they don't warn about issues! I have made all my now ~60 How To's as PDF's for a reason. I use pics and long captions. Can look at places where you have questions where there are issues and read caption. For example I used a Dremel tool and made a small semicircle to allow the wires to go thru. Video makes it look so easy to reinstall the back. It's NOT and wires sticking out don't help.

This is one of my How To, showing several ways I have used to install Blendmount wire tap:

I do use their wires as tried cheap one on Amazon I had to return! Below a very important Pic FROM MY PDF NOT mentioned. It's hard to see the black ground terminal. There is a gray wire next to it and if by mistake you put the black wire there it will cause the driver's door mirror to fail. There is a GM Bulletin for Techs that doesn't say where to tap (GM would NEVER tell you to tap) BUT tells a GM Tech if the driver's mirror looks like the one in pic below and there is a tap of the mirror NOT COVERED ON WARRANTY.

Pic Left is from Blendmount. Right is mine that shows not so easy to see black wire:

GM Techs are warned if driver's mirror looks like this NOT Covered on warranty as caused by mirror wire tap!


SIDEBAR
I'm not a Youtuber nor allow Youtube to put ads on my the ~25 videos I made for my business. They are more professional than most as all start with a Storyboard, just like the ad agencies used for ones they made for us in my former life before retiring and starting my own part time Internet business.

In fact my PDF's are that 1st step using a two column format, i.e. pic or video clip on one side and exact text on the other. For my video's may require three takes before I am happy with voice over. So easy to make PDFs. No restraints on length of caption!

For the Video's a lot more work. First is length. YouTube provides excellent analytics' showing for example when folks stop watching. Have to make short as you lose more audience as time increases past 5 minutes. Also have to use interesting transitions and "legal" background music. Not cheap or easy to find free! Smart to avoid cute intro's, just get to the point and better have a call for action (like where to buy) quickly.

Takes a lot of extra time from Story Board to finished short video. My PDF's are mostly just the Story Board, easy quick and can include what not to do or what to watch out for. Important to DIY folks like myself!

 

glad it was easy, I just can’t find anywhere on the windshield I’m comfortable putting a radar detector in this car. I had my R7 out and probably tried six locations last night and every one of them I don’t like because of blocking site. And the worst is underneath the mirror, that’s horrible. so I’ll use Waze and the heads up display and see how it goes.

 

I won't have that. Wires being pinched is never a good thing. I'll do the dremel thing like Jerry U did if that's the case.

Thank you JT. I have been dreading this job because of that very thing. Good suggestions.

I'm 6'4" 230. Guess I have some pain coming.


I know thank you.

Thank you Jerry. I have indeed seen this and it is helpful. I wish your pic was a little clearer. If it was a simple as the videos suggest there wouldn't be guys ruining their mirrors. If I can get a clear shot on this I will do it otherwise, I'll be putting my blendamount up for sale.

 

Please pardon my ignorance. Just what are you tapping? and why?

Inquiring minds want to know.

 

Need a power source for radar detector, popular option is to do so via the mirror

Take all my own pics for my PDF's BUT that one on right was from another video. Could not get a clearer pic myself. You'll be sitting sideways on your passenger seat to see! No it's not easy to see, the Blendmount pic is technically accurate BUT you will not see in that clear. If you download my PDF in addition to many pics you'll see I say best was to be sure it's the black wire is go to the row below the red wire (easy to see) and go only 1 wire over. It is black. Go two over as Blendmount shows on wherever they got that pic from and you'll be on the gray wire and break tour drivers door mirror!

If you want a safe way to do it than use what I did for the last year. Used the 12 volt receptacle under the passenger dash and mounted detector on the dash! Removed from my 2020 C8 when I sold it last month and that is what i will use on my E-Ray now at 3000 waiting for GM to build.

 

Do yourself a favor - Get a wire tap kit from Amazon. I installed 3 Blendmount systems; my C8, my friends C8 and on my new Z. The wiretap kit from blendmount has "blades" that are really difficult to work with. Get a kit for $12 and use the wires that are pointed - makes it a snap to install. This is the kit I used

 

If you’re going to post that, might as well tell them was WRONG means.

Correct: Tap RED to RED, and BLACK to BLACK.

Wrong: Tapping either wire to the GRAY on the rearview mirror socket.

Summary: Stay away from the gray wire and you’ll be fine.

 

This pic makes it clear! Pic left was from Blendmount instructions. No way does it look that clear when sitting sideways on the passenger seat!


It's not blue, looks like this. It's tied to the driver's mirror dimming circuit!
