mk2 golf rev guage.

Hi, I took out my speedo to change some of the bulbs, but cant find what the suction pipe goes onto for the rev guage. can anybody help?
I can locate the pipe on the back of the speedo which is like 10" long, and I guess it goes through the bulkhead to plug onto something.

If its an 8v digi then the vacuum pipe on the back of the clocks is used for the mfa mpg readings, it connects to the brake servo pipe, a small outlet on the right hand side of the inlet manifold.
