Installing Rio Grande Halfbreed

Hello,
Quick question here for ya...
I just acquired a Rio Grande Halfbreed bridge pup. I'm getting ready to install it. It does not seem to have a metal baseplate, so I'm guessing I'll need to ground my bridge plate. Just wanted to confirm that before I ran the ground wire to my bridge. Anyone installed and using one of these? Many thanks!

White wire to switch, black to the bottom of a pot. Simple as that. You should have a wire running to the bridge plate and soldered to the pot as well.

Thanks, Bhallguitar...
My Tele didn't have a bridge ground originally (was grounded through the metal baseplate of the original pickup). I figured I'd need to add the ground wire with this new pickup. The bottom plate of the Rio Grande doesn't seem to be metal, but I figured I'd ask....been surprised before:)

No problem. I have a Halfbreed in my Strat, a Muy Grande in my Tele. Love those Rio Grandes!
