I am installing an after market CIPA automatic day night mirror w/ temp using the Honda OEM accessory kit which includes the connection for the headliner. My CIPA mirror uses 1 & 7 for +12V and pin 2 for ground. The Honda plug uses 1 for +12V and 3? for Ground. There are three wires in the headliner connection, one a +12V, switched, one a ground and the other, I wish I knew. Does anyone know what the other wire is used for. I tested for constant 12V, and didn't get a reading.
Thanks from a newbee |

hey bgwiles! welcome to the .org!
i have never tested wires in the area you are referring to, but the only logical thing i can think of without pulling out a multi-meter is that your third wire is for illumination. meter the wire then turn on the parking lights, see if that's it. hope that helps! |

I'll test the other wire with lights to see if that is the option. I have also read that it may even be connected to the reverse circuit so that the the mirror does not dim while the vehicle is in reverse. |

I was able to find the information concerning the wiring of Automatic Dimming Inside Mirror Harness. The following pin assignments are measurements from the plug that attaches to the mirror.
Pin 1 - YEL/GRN = (Fuse 7 - Driver's) 12+V (Ignition)
Pin 2 - BLK Ground
Pin 3 - GRN (Back-up lights circuit)
This Honda connection fits the CIPA / Magna Donnelly mirrors. I personally installed a CIPA 36501 in my Pilot VP, since it did not come with an outside temperature gauge. Since the 36501 mirror has map lights, I had to cut the #1 and #7 wires on the CIPA harness and cut the YEL/GRN #1 of the Honda harness and solder the modified CIPA wires to the Honda harness. I used heat shrink over the new solder connection and the job only took 10 minutes.
The CIPA 36501 mirror pinouts are as follows:
1 = 12V+ (Mirror)
2 = Ground
3 = Reverse or Back-up lights circuit
4 & 5= Temperature Sensor
6 = Not Used
7 = 12V+ (Map Lights)
The Auto Dimming Mirror install time was as follows:
1. Temperature Sensor wiring from behind front bumper (Had dealer install - charged 1 hour, took about 1/2 hour total)
2. Honda harness modification - 10 minutes (cut the 12v+ back 2 inches and connect both 1&7 from CIPA harness.
3. Mirror install - 20 minutes (using the Honda Accessory P/N: 08V03-SJC-102)
This is a great option for those that purchased the VP and want the outside air temperature. |
