Wiring diagram for 964 speedometer?

[jsoderbe]

Hi,

I'm trying to connect my '90 964 speedo to my '86 Carrera. There are 5 pins on the back of my 964 gague, but there are no colors or numbers to tell me what function every pin has. So, anyone out there that could help me with an electrical wiring diagram, or tell me the colors of the wiring attached to each pin?

It is a really nice 300 km/h speedometer, which I don't want to burn to dust....


Thanks,

Johan

ok, this is what i have:
#1. OR - lumination
#2. WT/RD - output to various modules (spoiler, convertable top, etc..)
#3. BR - ground
#4. GN - pulse sensor input
#5. BR/BL - lumination intensity control.

Hope that helps..

Thanks guys, excellent answers as usual. Do you know how the pins are numbered? I don't have any numbers on the back of my gague....
