I was wondering if anyone knows if there’s an aftermarket rear diffuser with a third break light for the LCI m340i

Why?! It’s not needed and it ruins the look of the diffuser!

Agreed! Maybe you go often to the tracks, and wouldn't say you fancy going there with M340i. At least not often

VTEN diffuser which is the one Aerocarbon sells is an absolute pain in the ass to install since they are made for Euro bumpers and require a good amount of modifications to fit US bumpers. Can’t speak to the ease of install on the other one though. IMO the VTEN one looks the best as of now.

I’m usually not a fan of 3rd brake lights but this looks clean. Matches the rear reflectors really well

Agreed. I have never liked 3rd brake lights on any car. Only reason I got this diffuser is because it goes with the reflectors.

Sorry , probably a daft question, but what’s this for if it’s a break light down low?

What kinds of modifications did you have to do and what was the install process to get it to fit like you did on a US bumper? I’ve got one on order, I think it looks great on a blacked out car.

I have same exact one installed in my car, got it from EBay, finish isn’t great, fit was a lil challenging but I love it, it looks great installed, plug and play, piggybacks to outter tail light connector, light brinks a few times when you brake then just stays lit, light also blinks when you put on blinker or hazards

I purchased this diffuser but having some trouble figuring out how to wire it correctly.

How did you wire this up? I look at the inner tail light on the trunk and it's a 6-pin connector, different from the one that came with the diffuser. Did you have to splice the wires to connect it? If so, where and which colors matched up?

Edit, connectors attached in pictures below.

No. Mine piggy backs directly into the harness. You shouldn’t have to splice anything.

Thanks, I was curious if the piggyback wiring came with your diffuser, or if it was part of the car originally.....I didn't see a piggyback harness in the VTEN box I got, just that cable I showed that was connected straight to the diffuser.

If it didn't come in the box and I needed it, I'll probably just splice the OEM harness and wire it up manually. Looks like from others wiring up similar diffusers it goes black to brown ground, yellow to white/purple for power, and red to green for brake light activation signal.

Yup, it was missing the correct piggyback harness. Seller is sending another one.
