electrical end of the lock cylinder Options

[Kraftwerk]

(UPDATED with nice photo's below)

Looking find or restore the electrical end of the starter cylinder, where the black disc with the six contacts meets the copper bit has become separated. There was a tiny bit of corrosion and the switch malfunctioned. The lock and Key seem to be fine.
I left the roof off and rain got in there. (doh!) So I took everything apart to investigate the switch and contacts may be okay but its hard to tell a tiny spring popped out of somewhere, the other tiny spring is still in the center. The wires have been cut and soldered twice before reaching the 20 pin connector so someone has been in there before it looked kind of scrappy so I will make clean connections.
The car is a 1971, later build.


Secondly I want to drive my car since it is otherwise running like a top ( Thanks to Chris and Co. at Tangerine : )

Any clues on how to hot-wire it or add a temporary switch?
Here is a list of wires:
1. Red (Has a tiny burn mark on contact side)
2. Red and Black
3. gray
4. Black
5.Black and Yellow
Brown ( becomes Brown w/blue stripe)

thanks guys!
