Left side ignition switch conversion-Alternate Idea, Conversion is completed. Options

[jkb944t]

I am considering an alternate plan for a left side ignition switch conversion. My plan is to alter a standard 914-4 steering column to accept a left side 911 ignition switch including the locking feature.

I would remove the right hand ignition switch and possibly fill in the area like some others have done. The other option would be to insert a push button switch instead of the key tumbler and use it to energize a windshield washer pump motor.

I will need to get some dimensions shown on the photo so I know how to modify the standard 914-4 column to accept the 911 ignition switch. It would be very helpful if someone can help with these dimensions.

Finished up the ignition switch wiring harness this week. The ignition switch wiring harness wasn’t as hard as I expected since the wire locations at each end are basically straight forward. The wire locations are marked clearly on both the 914 ignition switch and the 911 ignition switch connector.

The connections are:

30-large red wire for main battery power
50-large yellow wire for starter
15- medium diameter black wire for fuses
X-medium diameter red wire for headlights
P-small gray wire for turn signal switch
?-small gray wire with brown stripe for key in ignition switch

I disassembled the 914-4 ignition switch to see if I could use the end of it to fabricate a connector. It would be much easier to just splice the wires into the existing wiring harness but I wanted to avoid cutting into the original wire harness.



I was able to use two of the pieces of the 914-4 ignition switch to fabricate the male end of the harness. I used a Dremel to cut slots down the side of the connector so that I could solder the wires to the contact pins. Once the wires were all connected I used JB Weld to seal up the slots on the side and back of the connector.





The next step was to disassemble the used 911 ignition switch connector.



I pulled all the wires out of the connector and then soldered in the new wires.



Below is the nearly finished wiring harness. I still have to figure out the gray wire with the brown stripe for the ignition buzzer. This isn’t real critical yet since I am not sure I even want the buzzer to work.
