On a W123 my guess is you need to pull the instrument cluster out. The instrument cluster is just pushed in but it can also be held in by the speedometer cable which you can pull on to give it slacker and I am not sure on the wiring.
The color coded hoses need to go into the proper position, or it won't work as it should.

When I did mine, I had to swap out the whole steering collum lock as that had pars inside busted up. So that valve came with the new steering collum lock.
Removing the steering collum lock is another way to get at that valve but remember the seat belt buzzer switch is also attached to that.
