First time builder of a guitar - what was I thinking?

I was talked into buy 2 Fender lace sensor humbuckers.
Of course the instructions are for a Strat. I am more inclined to the gibson sound and set up.

I am putting 4 pots - v/t v/t - a 3 way switch below the pots and the jack in a side mount position.

The lace sensors have two sets of wire on each pickup,each containing an orange, white and green wire. Where do they go - do you twist two wires together? Also, I know that I have to put a ground wire under the bridge - what do I solder the ground wire too.

If anyone has a schematic that a 3 year old can read, I would appreciate it.......the guitar is almost finished and so is my sanity.

One more question - I was giving 250k pots - should I have used 500k pots - the body of the guitar is mahagony and neck is maple. Will the 250k pots give too muddy of a sound?

My life for a schematic that makes it simple.

Thanks
