JB jr. installation

[MasterCapn]

I tried installing a jb jr into my jaguar today but it's super quiet.  I've connected both the green wire and the black wire to the same wire that connects to the bridge selection.  Am I doing something wrong?

Did you do this.

Red and White twisted together,does not connect to anything else.
Black to hot
Green to ground

[MasterCapn]

what do you mean to hot?

I connect once the black to the yellow wire that originally went to the pickup from the selector and the green to the ground and the red and white have been taped away all the times i've tried it.

I supose "hot" means to connect to either the lug of your selector switch or to the lug of you pot, as oposite to "ground".
CHeck the Seymour Duncan site for wiring diagrams. I use these all the time and they always worked. (even with non SD pu's involved)
