Having searched and found interesting threads like this,


I’m still wondering what two different pair of wires on my ignition barrel are (see last picture in this post).

I’m happy with this diagram for the ‘back end’

It is where these pair of low ampage black and white pair and orange/white and red/white pair fit into the diagram below which is intriguing me.

Why is a long story, however after having a couple of beers at Rhino Charge this year, I couldn’t find the keys the next morning. With a lowloader to meet that morning, I had to hot wire it. I then found the keys. Just solder the wires back on, you say. Yes, but I have a fun push button system and so will try to sort it all out onto that.

Just keen to know what the small diameter wires on here do…

Apologies, it is on my Mk1, but agreed, it could be on numerous Landies. Plot thickens a little. The black and white pair are closed with key in 1, 2 & 3 but not 0 so that makes sense for key in sensor. Guessing I can just solder those together?

The orange/white and red/white pair are open in every position, however I didn’t short the black and white pair when testing these two. Any idea what they need to connect to?
 
Ahhhh, understood, my apologies once again. My Mk1 started as a 200TDi but now has an auto 3.9 V8 EFi (with a Mk1 type gearchange), possibly from a Range Rover, so it is a bit of a crossover. I guess that is why the Mk2 wiring diagram seems to work for me.

Don’t you worry Sierrafery, my question was can I just connect the ‘key in’ sensor wires and don’t worry, I think I will just do that. My other question was “ what do the ignition key interlock solenoid wires need to do, if they run an open circuit in every position.

Perhaps someone else can hazard a guess?
