wiring diagram outside temp gauge
 

hi,
just wondering if anyone has a
wiring diagram of outside temp gauge for W124.
mine doesn't come with it.

i believe there are 2 types,
4 & 5 pins .....

i need wiring diagram for both :)

Thanks

The 4-wire is the early one, I'm not sure the change date, to the 5-wire.

The wiring diagrams are in the FSM, I don't have the pinout nearby.

The additional wire is for speed input which can be hooked to the junction block for the hall-sensor mounted to the top of the steering column behind the cluster.

what's the FSM?

Sorry. Factory Service Manual. Available from Mercedes on CD for around $20.

I paid much more than that. And it's a crappy FSM.
I can send you the wiring diagram if you wish.
