A couple things to note, if you get the Mikstore kit (not sure whether these apply to the more expensive Honda OEM kit on their site):
- The connector on mine was different than the car's mirror connectors. I had to de-pin and swap the connectors to make it work. I believe they have updated this since then and now include the correct connector.
- Setting the correct position is a bit tricky. I remember having to hold the mirror adjustment in the "down" position while putting the car in reverse, and not letting go until it was in the spot I wanted it. If I got it wrong, I'd have to repeat the entire process. Not sure if this still applies.
- The aftermarket kit I got had no way of disabling the mirror tilt. I quickly realized I mostly prefer to have it off, and only turn it on when I'm parallel parking. I ended up wiring a latching switch in line with the wireless reverse-signal controller. If you get the OEM kit, you should just be able to set the mirror switch to R(ight) when you want it to dip.
