On the right side, use all 3 grounds. On the left side, skip the ground on pin 8.
The blind spot sensors use the ground on pin 8 to define sides. So when pin 8 is grounded it defines the sensor as the right side, ungrounded defines as the sensor as left.
No, I haven't got the 2019 glass yet, it should be here next week, I am using some generic indicator LED's that I put behind the mirror glass and can see the reflection on the chrome mirror housings, I'll post a pic, I had everything enabled, but because I didn't have the indicators hooked up to the door modules, it would not let the system operate because of the active trouble codes in the door modules. After I installed the LED indicators everything worked correctly. I will update once I get the 2019 glass, it should be getting here Wednesday or Thursday
Yep, all 3 on right, two on the left skipping pin 8.
1st ground is for the tail lights, 2nd is for blind side sensor side definition, 3rd ground is for the blind spot sensor.
Another way to explain- both sensors sitting on the bench are identical with the same circuits to run them with two grounds. If both grounds are hooked up on both sensors, the can bus thinks there are two right side sensors. By NOT grounding pin 8 on the left side, the can bus can now differentiate between which one is the left side and which one is the right side.
If you’re not running the blind spot, you only need to use pin 5 as the ground for the lights.
Paint the masking tape with the metallic paint before committing. The metallic paint may mess with the sensors.
Got some leftover color match from when I did headlight housings going on the tape right now.
Go big and just get some super metallic rattle can from an auto parts store to make it a worse case scenario. Throw two layers on and see how it does.
They are pretty bright. They are at least on par with my LED tails. The reverse lights are brighter by a huge margin.
