I put a seymour duncan hot rails and 500k volume pot in my 70's fender bronco. I thought I wired it up right but now when I plug it in the tone pot seems to be controlling the volume and the volume doesnt really do much. What have I done wrong?

I have the black wire from the pickup going to the bottom of the volume pot and to the top of the tone pot. The middle volume is going to the jack. The top volume is grounded. The middle tone is to the capacitor and the bottom tone is empty. Thanks!

the other jack on the input jack goes to the back of the 500K
and connect a wire from the back of the 500K to your bridge plate

here's the schematic in case you missed it http://www.seymourduncan.com/support/wiring-diagrams/schematics.php?schematic=1hum_1vol_1tone
