I think it looks good, wonder what to tap to get light to work without throwing codes if any.

Burr001 · 04-17-2023, 05:37 PM

hmmm this with my new exhaust on order...

Burr001 · 05-15-2023, 06:19 PM

So it finally arrived, good looking piece. Quality seems to be on par with OEM. Hopefully I get some free time to install soon.

Have you figured out what to tie into for the brake light?

I will most likely tap the right rear tail light as I'm using the same grommet for access into the cabin with the exhaust valve wires.

Can someone find me a wire diagram for the rear tail light pigtail? if not i'm gonna be trying every wire till it works...

yeah its probably best staying away from using the "hole in the sock, toe on wire" method!

Applies to: P552 (Adaptive LED headlights) -2021/06, P5A4 (LED headlights with extended contents) -2021/06. Is this what you need?

OMG...your DA MAN....Thank you.

Looks like for the right rear outer tail light its brown for ground, and green/gray for brake light.

Hopefully I'll be able to do it this Sun.

There are 3 wires coming from the diffuser, I'm guessing one is to have the light flash under braking.

I'll see what happens when I connect both to power and confirm.

Looking forward to your feedback. Looks like an interesting mod. I wonder if it would fit the M exhaust with the round tips...

The opening is about 8 inches if that helps, not sure what the M exhaust size is.

So yellow wire is for constant light and red is for flashing brake light.

So don't know if the flashing will be annoying to others, but at least they will notice when i'm braking.

TacosRule! · 05-18-2023, 02:08 PM

Kinda looks like an F1 car. I like it with the flashing/strobing light. Nice contrast to the OE lights. I'd do flashing instead of solid.

And that's all I'd care about. If it doesn't annoy them it means they're not paying attention. Great looking mod.

Good point, agree 100%

Shaun170 · 05-19-2023, 01:53 AM

Not that it effects you guys where you live but in the UK flashing rear red light is illegal unless it’s on a Police car or Fire engine.

Burr001 · 05-19-2023, 03:23 PM

Ok so I just removed my rear bumper and the f ing piece doesn't line up with all the clips into rear bumper...the middle ones are off, but the side clips line up.

Lol so don't buy this one...

Rottweiler suggested I can modify it and remove some of the clips and it will fit better...I'll take another shot at it sometime later when I have time...or contact the seller.
