1972 Steering Column Blues

[david58]

Need some help here with the wiring and the parts above the turn signal switch to make this column work with a aftermarket steering wheel. 1972 914

We need to see the wheel side. Ray

OK but I am using a Steering Wheel Quick Disconnect like this.

I need to see the stock wheel side.

Red/Black(thick) is Radio Supply (on in Positions 1,2,3)
Red/Black(thin) is power in (30) to key-in switch
Grey is Off (on in Position 0 - key in or out)
Black/Red is key-in switch output(*) (on when key is in)

Switch Position

My wire colors aren't quite matching up on the Porsche Ignition switch.

My Ignition Switch has 7 wires.
I tested the switch with an OHM Meter and these are the results I got. I am not understanding why I have no continuity in any position on the gray wire with red stripe, see the Bold Red High Lighted text below.

Large Red wire = Power in to switch
Large Yellow wire = Input to Starter
Medium Red wire = Power with Key On Only (I am thinking I can use this to turn on lighting)
Large Black wire = Power with Key On and Start (I am thinking I can use this to power up the fuse panel)
Small Gray wire = Power with Key Off Only (most likely for dome light, when door is open)
Small Gray wire with Red Stripe No Continuity to power in any position (most likely ground for key buzzer)
Small Black wire = Power Key On and Start ( I am thinking of using this for the Parking Lights)
