I have a 2.5 NA Diesel that I have a new 300 TDI ignition switch for. Does any one know how to adapt it? Does it require a relay for the glow plugs? IS it possible? Thanks!

For the old switch, this is the wiring and the plugs it corresponds to:

1. White -Ignition
2. Brown/Red - Glow Plug
3. White/Black - Solenoid
4. White/Red -Starter
5. Brown - Perm 12V





For the new Switch
1. Red/White - Starter
2. Brown - 12V
3. White-ignition
4. Blanked out. (no terminal)
5. "Accessory"

Ok, this is the later switch, and I do have the glow plug timer relay. I suppose I would just run one of the wires that is active while the "run" position is on, to the glow plug timer relay (plug 3 -ignition) on the new switch?) Thank you for your assistance Uncle Douglas!
