    Based on this and the picture I provided this is exactly how I have the Honda wire harness connected to the 10 pin pigtail...

    Bumping this a bit, but I just picked up a Gentex GENK41A mirror and noticed it will take some work to fit on my Si. It has the wires coming out of the wedge and not exactly the 453 plug.

    I'll follow the wiring diagrams and helpful advice from this thread. I'm an electrician by trade so I will see if I can get this setup to work.

    I also ordered the OEM attachment, 08V03-TBA-100, so I imagine splicing that won't be bad as long as I can make sure the wires are properly marked.

    I got Honda OEM Harness 08V03-TBA-1A0 but the plug does not match the Gentex Series 8 Auto Dim w/Compass and Homelink mirror (frameless). Can you tell me exactly which model you got?

    The Honda harness is on the left, the Gentex plug is on the right

    I managed to install everything. The wire colors on my Honda harness were different than you specified so I used a multimeter to find the ones I needed. The Posi-Taps pictured were temporary. After plugging things in to confirm they worked, I cut off the connector entirely and spliced the wires into the Gentex plug.

    Gentex 50-GENK85A
    Honda Harness 08V03-TBA-1A0, 14 pin connector, 5 wires: yellow, light gray, light green, black, purple

    Light Green - Ground - Gentex Outside Black Wire w/ground loop
    Yellow - Constant 12V - Gentex Middle Black Wire
    Purple - Switched 12V (Ignition ON) - Gentex Outside Black/White Wire
