Installing P-Rails & Triple Shots on a JTV89F. Anyone else tried this? in James Tyler Variax Guitars / Workbench HD Posted December 7, 2016 Very cool. Does this mean the pos 2 and 4 do nothing? I have a 89 body here and was trying to figure out how to maybe wire with three pickups. I guess I can run the two leads from the p rails to both where you have yours connected and in parallel to where the plit coil would go. Then on both pickups just put middle pickup in parallel with the leads going to where the split coil would normally go. Position 2 is the same as position 1 and position 4 is the same as position 5. For what it's worth I ended up going back to the stock humbucker on the bridge, so I just have the one p-rail in the neck now. Wouldn't have a clue regarding three pickups sorry.
