Chuck's JZA-1

Yep, point A connects to the 5-way where the bridge pup does in the 1st image, and point B is the middle (out) lug on the volume pot.

insulating the braid (ground) on the P90 will stop it from shorting on anything but the poles will still be part of the 'hot' signal path in certain positions, so you may get some noise if your finger tips ever brush them. Also, in those same positions the braid is carrying the 'hot' so while it's now insulated it is not 'screened' from noise as it would be with a ground around it. Good cavity shielding should help to minimise most of this though.i

And, nothing special is needed fthe bridge pup ground, just cnnect it to whatever the closest or most convenient ground point is near your blower switch.

Thanks Scott, that gives me the confidence to start having a crack at it tomorrow!
