    Is it possible to do the Bill Lawrence 5 way mod with a humbucker at the bridge and a dpdt on on switch for coil split.

    Yup. Here's a diagram, using SDuncan pickup lead colors. Obviously you need a 4-wire humbucker to split it.

    It looks confusing, but if you're already familiar with the Lawrence wiring, the only change is to tie the red+white together, at the switch, and when it's engaged, connect it to ground. That shorts out the north coil, and leaves you with the screw coil active.

    If you wanted the slug coil active, to be a bit further away from the saddles, then you connect that gray wire on the toggle switch, not to ground, but to the five-way, same lug as the south-start is connected to.

    Once again thank you for your help. My humbucker has dimarzio colour coding but I think I can work it out by your diagram. Just to clarify something on the diagram it mentions string ground and B- what do these mean. I'm assuming string ground goes to the bridge

    Oh, shoot, ignore the B- . Sometimes I draw just the terminals of the pickups, and not pictures of the pickups themselves. This is a cut-and-paste error from that method of doing it .

    Yes, string ground is a wire from the bridge plate.

    Cheers my friend would you believe there's no ground from the bridge in this tele I'm working on.

    No. I.wouldn't. Meaning, the bridge must be grounded some way. All metal parts on an electric guitar will act as antennae if not grounded.

    See if it's grounded by metering resistance between output jack collar and the metal bit in question.
