Wondering what this plugs into
I was wondering if this blue plug goes into the fuse box

If you are looking for a car that is both sporty and economical, look no further than the 1990 Honda CRX. After economical and reliable, the favorite trait of this car is: fast.
The biggest complaint is that the car is too small, and has no back seat. Apparently it is exactly what it was designed to be, an economical sports car - and not a practical family car. If you find anyone willing to sell his or her CRX, you might be able to buy it for under $700.
I was wondering if this blue plug goes into the fuse box
Sooo. My problem started out more then several months ago. I shelled out $2400 in repairs to get my car running efficiently. After having my car back for a week and a half. My battery light flickers off n on. And occasionally stays off or will stay on. From take off at a light to shifting gears the battery light will turn on. I've had a battery installed and I've replaced my starter. I'm stumped, because I'm trying to figure out if my alt just killed my new battery or if my battery is just crap. I've got an AC Delco. I know that AC Delco isn't exactly the most reputable for a having long lasting batteries. I've checked my connections and grounds, everything looks good. Help me out here
I just replaced all break shoes/pads in my CRX, as well as faulty Wheel break Cylinder. now the car brakes but the pedal gradually goes all the way down. not sure how to test if I need a new Master brake cylinder or a new power booster? Also, my parking brakes are all wacked, when pulled, they do not stop the car. I may have to check the cables this weekend. BTW, I checked the vac hose to the booster and no leaks detected, as well as the one way valve .thanks.
