I'm trying to wire in my aftermarket bcs and I cut off this plug thinking it went to the stock bcs but now I'm not sure it did as my new bcs isn't working. My car didn't come with the stock bcs so I can't see if its the right plug or not. Can anyone confirm that the bcs plug has the little piece coming off the bottom like this one, or does anyone know what this goes to?

Thanks in advace

 

Looks like the original BCS connector. Ill run out to my car and double check for you..

 

Yea thats the stock BCS connector plug for sure..

 

Awesome thank you for the info I appericiate it. Now to find out why its not turning on LOL.

 

Did you get the signal/power wire (-->BCS plug) with a multimeter? That would be a good place to start.
