Hey everybody! Here's the question:
Do I need to install the relay mentioned here
in order to get my "courtesy lights" to turn on when I open the door and off when I close the door?
Here's the skinny... other than me...
Bought an auto-dimming homelink mirror with maplights and "mood lighting" (amber... it's really cool, btw) from a 2005 Chevy SSR. I believe this is actually the 50-GENK42, which is no longer available, though it's stamped with the model number GNTX-341. Based on the table below, I have routed the wiring as follows:
SSR Mirror harness
pin 1-2 Not Used N/A
pin 3 BK Ground Used black wire on our mirror
pin 4 GY Automatic Day/Night Mirror Signal Not planning to use this
pin 5 OG Battery Positive Voltage Used Blue/White Stripe wire on our mirror
pin 6 PK Ignition 1 Voltage Used fuse tap on #20 (spare) at 15A - for sunroof, I think?
pin 7 L-GN Backup Lamp Supply Voltage Not planning to use this
pin 8 GY/Bk Courtesy Lamp Supply Voltage
pin 9 PK Automatic Day/Night Mirror Low Reference Not planning to use this
pin 10 Not Used N/A
I used our gray wire, which I understand to be the auto-dimming signal wire coming from the BCM referenced from posts by JRinKY (thanks!
) to the pin 9 GY/Bk Courtesy Lamp Supply Voltage; only nothing happens. I'm guessing I need that relay (probably solid state, as if you read the above-linked post, the mechanical relays get "chattery" as they resist.)
to having the mirror I want, and one I believe should have at least been optional
on all our cars, but I really want the courtesy lights to work, too. As an FYI for anyone interested:
- The homelink and white map light are "always on" and both work (the LED maplight is button-activated)
- The auto-dimming is on ignition switched from fuse 20 and it works, but I can deactivate it from a button on the mirror face
- The amber mood lighting is also on ignition switched from fuse 20 and it works (and it looks REALLY COOL, too!)
