Uniden R3 Mirror Tap from Blendmount.
Nice but a little pricey for what it is.
Seen in a YouTube video, to get the cover off, you just have to use your finger and apply pressure to the seam on the middle of the cover near the top and it'll pop. Worked great.
Could not fit the tap into the mirror power plug, so went to the sensor tap (higher connector/red)... Used info from an earlier post, confirmed 12V with multimeter. Tap went in very nice. Secured wire with ty-wraps provided. Left the rest of the cable slack loose in case I move the R3.
From earlier post: The connector, with three wires...
Black (left): Ground
Purple: (Center)
Red (right): Live
I hooked up to the 12V power, but the wires were different colors, which in the M240i XDrive was:
Black/Brown (left): 12V- (Black on Tap)
Purple/Gray: (Center)
Red/White(right): 12V+ (Red on Tap)
Question is this... The Purple/Gray... Is this a switched 12V?
I just connected it to 12V constant for now, but would change it if anyone has access to wiring diagrams and can confirm what the purple/gray is. I would rather have it on a switched circuit, but not a biggie.
Thanks for this how to.
Made the job easier.
