I found this hanging around my driver's side wheel today and looked around as to what it might plug into and can't find anything? I have an 05 MR and don't have any warning lights on except for an ABS light. Any help is greatly appreciated! Thanks.

edit: also all of my headlights and turn signals work as well.

 

Side marker light in the fender

 

it's plugged in and they both work when I use my signals.

 

Look for a missing female end within reach....start digging around with your hand.

 

I've tried for about an hour and can't seem to find anything? Guess i'll have to start taking stuff apart!!

 

What about the stock BCS? Seeing as you have a MBC in place. I don't know if a CEL would come on with it unplugged though.

 

I've thought about that too and that's what made me post here because I bought the car with the boost controller on already. I used to have a GSX and it seems like I had to unplug or get rid of something on it to install the controller on it which is the same one that's on my car now.

I was kind of hoping it had to do something with the ABS light because this winter I found out that the light wasn't on for no reason, as was the case with my old GSX, and when I tried to stop in the snow my car shut off for some reason every time the ABS system should have kicked in.

 

Stock BCS, i know cause i just moved mine.

 

That was one of the things I was thinking it could be, good to have a little reassurance. Thanks!!

 

YUp.

 

agreed, bcs

 

It shuts off because you're making the wheels come to a complete stop (by not having abs functioning). By doing that and having the car in gear it will make the engine stall.

I agree check the BCS
