How to Install a Carbon Fiber Rear Diffuser with Rain Light (BMW F82 M4) 

the install is pretty straight forward you shouldn’t need a shop for it. the cables are more less the same from my experience

i can’t confirm but the yellow cable can potentially be used as a day time running light, i’d just tap each connection pin with the cable to see what effect it does before splicing anything

@@andywates7442 ooff i didn’t look at the amps but i assume either one would work. the lights are pretty low power it’ll only draw as much as it needs

red to blue/black (positive) and black to brown (ground) i haven’t figured out exactly what the yellow cable was for, i’ve heard that it’s used for some flashing or strobe effect which im not sure if you need an additional module for

@@RickyMotothanks bro im installing mine on Friday

Nice one Q- yellow wire is no function?

@@jonnellas7680 after doing some research it’s kinda like a multifunction cable either for a running light, signal, or reverse depending on how it’s wired.
