 Posted: Tue May 24, 2005 8:27 pm Post subject: Replacement Ignition switch question |
 |
|
The fried ignition switch that I am replacing has only three wires. Black, Red, and Red-Black, However the unit I bought from CIP1, which is susposed to be for 68-70 has four wires, Black, Black-White, Red, and Grey. I can get black to match with black (15), red to match with red (30), red-black to match with black-white (50).
The odd wire seams to be grey (P).
Can somebody clue me in?
Thanx

Im sure you've solved this, but I was looking for tutorials on replacing the ignition in my 70 and came across your question.
Here's a link to the best answers I've found if anyone else searches and finds this. Below is the link, and a quote from the tread.
Hope that helps.

As the ignition switch "evolved" more wires were added to provide more functionality. Some of the aftermarket replacement parts use the same later-model switch for their earlier-model replacements. This means you get additional functionality and more wires.
Basic wires since '68:
red (30) - INPUT constant 12v source from battery
black (15) - OUTPUT ignition switched 12v; power in ON/RUN and START positions
red/black (50) - OUTPUT starter solenoid; power in START position
Additional wires since '68:
black/yellow (X) - (added in '71) OUTPUT accessory switched 12v; power in ON/RUN only (powers headlights, wipers and blower)
grey/black (SU) - OUTPUT to door switch/buzzer; ground while key is in the ignition
grey - OUTPUT 12v while key is OFF
*You should test the grey and grey/black (brown in your case?) wires to confirm their function. |

A bit of extra info, also for those who might find this thread searching...
The grey (12V when switched OFF) is to support the European parking light wiring, and is not used on USA models. |
