I only recently bought my 2005 Yukon and the prior owner put a new master cylinder on it. There is a plug receptacle on the side of the reservoir but nothing plugged into it. I assume to warn if fluid is low. I do have a "service brake system" light that comes on and was wondering if that has anything to do with it? Brakes work and feel fine. I looked all around the engine bay and can't find a connector that would plug into that receptacle. Thoughs?
