On mine, the fuel pump relay is green. Yes, it was supposed to be in the black box with everything labled, but somebody put another relay in and didn't bother to remove the one from the box. So it's just hanging there.
What's going on with yours? Mine has a bad connection somewhere and about every other time I run the Bronco, the fuel pump won't shut off after it primes and/or won't shut off after I shut the truck off. We have replaced the relay twice and nothing. So for now, when I shut the truck off and get out, all I do is pop the hood and jiggle the relay a bit. That shuts it off and sometimes makes it work properly when I start up again.
