Harley Davidson Ignition Switch 3/4" Hole 71425-77

Additional Information

Fitment Information

• Can you please explain rear poles placement B[battery) IG(ignition?) L? Is the a ground placement. Pole that I can use to ground wires coming from bike to be grounded

  EMGO does not provide instructions with this switch, but the "B" pole is for battery. The "L" pole is for your lights and the IG is for your ignition.
  Without a wiring schematic, I don't know what color wires are in your harness. But you can find that information in a factory service manual for the bike.
  
  I also found this information in a forum on line that might help as well.

  "I bought a new aftermarket ignition switch, its different than the aftermarket one that was already on and the one that was on was not marked in any way. the wire colors are BLUE, GREEN, WHITE. On the back of the new switch its marked B, IG, L. What wire goes where?" I do not have the FM colored wire schematic here but you should be able to determine it with a little testing. On the Switch's back side: B = BATTERY, IG = Ignition and L = Lights. First take the BLUE wire and touch it to the the GREEN to see if the Lights will come ON.
  If not then try to start the engine. If starts then one is the IGNITION. Next join the GREEN and WHITE together to see if you have lights or the engine will start. The wire that both turns ON the lights AND starts the engine is the BATTERY or +12v. The others or determined by elimination. Another easy way is to use a 12v light bulb - if you do not have a multi-meter. Here you take each wire in turn an touch it to the side of the lamp brass base then touch the soldered tip to a grounded or bare point on the engine. Only one wire will turn the light ON so it's the BATTERY."
