Hi everyone. I wasn't sure what section to put this post in. Mods if this belongs elsewhere please move.
I know there are a few Gentex mirror install posts and those definitely helped. Below are the steps I did for an install of the Gentex 40A on a 2012 CR-v.
I used the Honda dimming mirror installation as a guide which could be found on collegehillshonda (http://www.collegehillshonda.com/ins...ightmirror.pdf) or handa (http://www.handa-accessories.com/crv/12mirror.pdf). What I did differently was to first remove the panels around the steering column to get to the fusebox and figure out the electrical hookup first. The reason being was I wanted to make sure mirror worked before disconnecting the battery. I used an add-a-circuit and used fuse 23 which is listed as the rear wiper circuit which is a switched circuit. This fuse actually affects both from and rear wipers. I chose to use a switched circuit since I park my car on my driveway outside and donít want the homelink working all the time. I may revisit this and check the empty fuse banks 18, 26, and 31 and see which one is switched. If I use one of these do I still need to put a fuse in the top bank of the add-a-circuit?
1. I removed econ panel. It helps to move the steering wheel all the way up and out. Then, you can reach between the steering column and the right side of the panel and pull it out from there.
There is a single connector (blue) for the econ button:
2. Removed the dashboard under panel (no picture).
3. Removed the driverís dashboard lower cover. I started with the right side of it and worked my way to the left. In the picture below you can see the part I started with (right of steering column release):
There is a single connector (white) for the VSA button:
All dashboard panels removed:
4. Removed the driverís dashboard side cover. This was a bit of a pain to remove. There are holes to get to the tabs but pushing down on them didnít help. What I ended up doing was to pinch the bottom tab and push out the bottom part of the panel. Then, released the black tab. After that I just grabbed the bottom part of the panel and pulled the rest of it out.
Pulled door seal:
Tabs of the panel:
5. Took out fuse 23 and with a multimeter made sure it was a switched fuse. I also determined the top connection of the fuse bank is where the power comes in from and made sure the pigtail side of the add-a-circuit was on bottom side of fuse bank (if this is incorrect please let me know). I connected the wire taps to the add-a-circuit and taped off tail end.
Add-a-circuit in fuse bank 23 (please let me know if I have the add-a-circuit backwards):
Hard to tell but behind the green/blue wire (car starter wiring) you can see the red wire of the add-a-circuit and the 2 wire taps into the add-a-circuit:
6. After testing the mirror worked with my wiring, I disconnected the negative terminal of the battery.
