Hello all, have gone over what I think is almost every thread on adding heated mirrors to the non-heated mirror models like the LX models.

I believe it can be done simpler, so I am starting a new thread and will add new information to it to make it a write up for those who may want to add this to their own 2nd gen CRV.

I have confirmed that we share the same switch as the Pilots and purchased a brand new mirror switch with the heated button on it from an ebay seller - drvidguy

Circuit component Passive circuit component Electronic engineering Hardware programmer Electronic component





Here is the switch he sells:

Camera accessory Rectangle Computer keyboard Bumper Communication Device


Composite material Rectangle Automotive wheel system Metal Engineering


Circuit component Electronic component Gas Electronic engineering Rectangle



The switch was pretty cheap ($14.96) and brand new so no old used stuff there.
I ordered a pair of heated mirror replacements from amazon:

I removed the original switch from my CRV and popped in the new switch and it fits perfect.
(I forgot to take a picture of it installed, but needless to say, it fits and works normally as the OE minus the heated mirror switch part, Yet!.)

I am comparing the pins in the back so I can determine what pin locations I need to add and run new wire too the replacement mirrors that should be here in about a week.

I will update this thread as I make progress so it will be a complete write up.
Of course for the more experienced CRV owners, I welcome the criticism and pointers as I am not expert on this chassis.

I have focused my original efforts on supporting and maintaining my main project car - 88-91 Honda Preludes.
As like most of us, I am a tinkerer so doing little mods like this is fun for me, I hope this helps those who were looking to some thing like this too their 2nd gen.

Too be continued.....

What year model is yours? That would also help those reading. AFAIK from my 2nd Gen 02 V's only Canada model had this Heat and Daylight running option. So if your was a UK, NA version those didn't come with this option. But since we don't know the year model others won't be able to help here.

I put heated mirrors on my 2007 CRV LX.
I found there was no wires to support heated mirrors.
None in the mirror nor in the cabin.
I found a way to get the wiring from the mirror to the cabin.
The mirror requires a little disassembly to fish the wires thru.
Then after getting it to the connector in the door, to fish the wires
thru the rubber between the door and inside cabin.
All to keep the wiring altogether and looking neat.
I went with a device to turn on the heated mirrors with the push of the button
It would then let ten minutes pass and then turn off.
ThermaSync 2700 r series from Amazon. That made it easy to hook up.
Power came from "Add a fuse". Ground was chassis.
Must mind the terminals and which one has power and which goes to load.

Your method seems to go with OEM and made to look like factory put it in.
Very nice.

US model - The title says the year and model.
I just edited the title to specify.

I read your post on how you did that, it was and is still a consideration. I will be figuring out the correct wires on the switch that will turn on the heat for the heat element in the mirrors.
I have to definitely run a power source for the heat element through the door jams to get power too that part.

I was trying to figure out if there is a 12v source at the switch that I could tap for that source, but I have not found it, yet.
So still trying to figure this out.

There must be a power source since the power mirrors work??
Volt meter, one probe to ground and the other probe testing each wire to mirror motor
Should let you know which one is power. Then just a matter of tapping into the wire.
Please keep us informed about your progress. Thanks

Here is the current pinout for the power mirror switch connector...

Font Rectangle Slope Schematic Parallel


Per the tech manual, when on the ACC II ignition position there should be power coming from Terminal No. 2 - BLK/YEL wire.

So I am thinking of tapping that wire for the heat source for the heating element.

Update:

Today my friend and I tackled trying to figure out the wiring for the new mirrors which arrived last Thursday.

After some searching we found the female part of the connector for the Heated version of the CRV mirrors for 2002-2006.

Electronic device Auto part Automotive exterior Machine Plastic


Link to parts: Sumitomo HD Series Automotive Motorcycle Motorsport Connectors - Corsa Technic



After looking into the US tech manual, we figured out that we have to run a single wire from the drivers kick panel across the entire dash too the passenger side kick panel.
We found the connector that plugs into the door from the chassis side.

Rectangle Font Space Darkness Composite material



Finger Thumb Nail Creative arts Wrist




This connector is on the passendger side kick panel but the driver side has the same connector.
As you can see from the back, there are 5 open spaces available.

1 of those spaces will be for the power coming from the driver side switch too the passenger side to give power for both mirrors.
I ordered the new connectors to build a harness that plugs and plays, and will be wiring up the switch harness as well so it all works as OE.

More too come next week.
We are getting closer. ;)

Nice.....should give links on where you found the parts so others if they want to do the DIY they can take the challenge as well.

Update:

Ok, so we got the parts in this past week, and we hit hard and fast.


We swapped out the 3 pin US model connector for the Canadian model 6 pin female connector.
De-pin USA Gray connector and re-pin Canada 6 pin connector. Follow the pin locations on the tech manual.
The easiest way is to de-pin one at a time and re-pin the corresponding pin location on the new connector, that way you do not mess up the re-location.

Next we pinned the power source and ground wires on the new connector.
Power for heat control was on pin location 1 on the connector, and ground was pin location 2

Black is the ground and it was spliced into the ground on the existing harness.
The white is the Heat source wire.

Here is the connector pinned and measured out too make the connections on the switch connector.

On the switch connector, you pin the empty slot with your power source wire, we reused an Acura TL connector that had the female pins with the same color scheme as the CRV's. So we found out that the 04-08 Acura door connector is the same setup as the CRV/Pilot of the same years.
Orange colored wire is the new source for the heat control from the switch.

The white wire is then spliced into the Orange and send backwards toward the door back through the door harness via the rubber boot.

Here is how we spliced the Black ground wires and pinned them to the switch connector.

We pinned the ground and also the power source from the harness, which was Blk/Yel.
As you can see its the two outer slot locations on the switch connector.

Yay!!!! 🤩🤩🤩 Success!!!!! It works. Now unto wiring the source wire from the driver side kick panel and running

Taped up the harness after all connections were made, and then put the weather seal back on and then tested the
switch.

Next we moved too the pinning of the heat source wire (white)

We pinned the OE location if this would have come with the heated mirror.
The Red wire is the source wire we pinned and then but connected to the white wire to run across under the dash.

We pulled the harness back through the door too be able to access the rubber boot and run the heat source wire through it.

And walla!!! All done.
I now have heated mirrors, I hope this helps those who were thinking about doing this.

Thanks guys! Been doing stuff like this for my 88-91 Prelude community.
As with all car guys, we are never really satisfied with what we have...lol

Its fun uprading or adding stuff our cars did not come with. ;)
