Giving up on ignition switches, Need wiring diagram, Bought a universal starter/ignition switch.. Options

[Andyrew]

So my 3rd replacement ignition switch started tweeking out on me. Im tired of this. This is not a stock 914 so I decided to get an aftermarket switch. 10 bucks at Autozone and I have a switch that I doubt i will ever break.

So I pull the wiring which I have become so familar with and see that there are 6 prongs on it. One obviously ground(Black), One obviously power(red, thick), One keyed power (red, thinner), and one obviously starter(yellow).. But then I see 2 other small wires, a white, and a white/brown. Where do these suckers go? There is no accessory switch to the 914 so I doubt anything can go there, Are they the wires that are keyed power or say a relay? How do I wire this on a 4 prong switch??? I would think that the two smaller wires just go on keyed power, but I'd hate to do it and be wrong.


Thoughts?

Thanks all.

I'll give it a test tonight. Battery is kicking 12.3 volts as of last night. I havent had the battery on a charger in a while. Optima Red battery, 1 year old, barely any miles (maybe 2 charges on a charger, it held a charge really well).

Try these things. (1) Sub in a different battery. Optimas don't like to sit. I've seen multiple failures on cars that sat for long periods. (2) Your description of the importance of position leads me to suspect the steering lock assembly. I'm sure someone here can loan you one for testing purposes. Look for movement of the tab corresponding with the movement of the key. (3) Check the voltage FROM the battery at rest and then with the key in the start position. If the wire from the battery to the switch and fuse panel is bad, it can measure OK and fail to carry battery voltage when loaded. If the cable to the starter is bad, same thing. We've heard of 911s with the battery cable unable to carry 12+ volts to the starter. Pretty common, actually, and that sucker is REALLY hard to replace. (4) Verify your grounds UNDER LOAD!

Report back.
