Speedo wiring trouble PLEASE HELP!
 
I took my gauges out to install some carbon fiber. I marked all the wires so I would know where they went. Somehow I messed up with the speedo. Can someone post a diagram or pic (prefered) of the wiring that goes to the back of an "electric" speedo gauge. The one that is in the technical articles is gear driven so it doesn't help. PLEASE HELP before I go nuts.

BTW: its a 1976 911s 2.7

Something is up. There was a black wire stuck in the bulb holder (see arrow). When I pulled the gauge out it pulled out from the other end. Anyone know where it could have went?

Terry if you fig it out please let me know. mine has been giving me hell for the last month. Cant get it to work!!!!!!!!!!!!!!!GRRRRRRRRRRRRRRR!

Looking at the back of the speedo, the group of multiple terminals at the right side of the gauge are, from left to right:

two brown wires andone brown with red stripe
one brown wire with red stripe
one red/white wire and one brown/black wire
one red/black wire and one red/blue wire

The bulb socket at the bottom gets the bulb with the black/blue wire.

The bulb socket at the top on the right gets a bulb with a black/blue wire.

The bulb socket at the top on the left gets a bulb with a white/green wire.

At least that's how it is on an '83 SC.
