I have the J45 pickups from Wilde Pickups it has 3 wires, White (Hot) Black & Blue (Ground). Is it best to just: 1: Keep the grounds twisted together and solder to preamp? 2: Take Blue ground wires together and electrical tape them off & solder only the black wires to preamp? 3: Or just tape off the blue wires individually and solder in only the black ground wires? Thanks!
