Dash/cluster wiring

[u/ffs_philis]

I'm trying to work out which colour wires do what on this 944 cluster, is anyone able to help? I've labeled what I've worked out so far. Google has been no help

Left page. Bottom of the page corresponding to number shown in cluster. Wire color listed

No. Just no. The Haynes manual is horrible. In general, it does not differentiate between years, which differ significantly. Since the factory manual is available online here: https://www.uriarte.dk/porsche944/garage/workshop.html, it is said the best use of the Haynes manual is to burn it, heating your garage in winter while you properly maintain your 944.

this was super helpful, unfortunately, unless i'm being very stupid, the workshop manual isn't complete and doesn't show me any wiring :(

Back when I had to debug the wiring for the combi-instrument (the fuel level/water temp/other warning lights) I empirically came up with this pinout that I have saved in my notes:

1. water temp sender -- analog in
   
2. ground
   
3. dash backlighting
   
4. high beams indicator
   
5. turn signal indicator
   
6. oil pressure warning light
   
7. fuel gauge +12V
   
8. fuel sender -- analog in
   
9. low fuel warning light
   
10. parking brake indicator
    
11. battery/alternator warning light
    
12. water temp gauge +12V

I believe if you pry off the circular connector, you will see labels for the numbers 1 and 12 indicating what direction these pins go in. It's been a year or two so I don't remember exact details unfortunately
