The speedometer has 3 light sockets, are they interchangeable?
In other words, does it matter if I don't know which one goes where?

Is the wire for the bottom one a different color or how do I identify it?
Thanks Mark, that is great!
It is a little hard to tell the colors
I have the blue book, I will scan that page and enlarge it
fortunatly the multi gauge as all the lights in place, I can do one at a time
Illumination is grey.
Mark,
All of the gauge illumination bulbs have grey or grey/blue wires; the functional bulbs have their own specific two-tone colors, black/white for the speedo hi-beam lamp.
Thanks! this is great
Fortunately the mulit gauge has all the wires and bulbs still in place, I can switch the bulbs one at a time
Where did you find the colored wire diagram?

Wiring diagram - late '73 - '75 e9's
I have searched several times for a wiring diagram of our e9's that were built late in '73 through '75 (I have a '74). There are quite a few changes made to these cars, but one specific and easy to spot one is the wiring/mountings for the window motors. The late cars used 2 wire connections...www.e9coupe.com
