Rd28t diff lock vacuum diagram

[Larskramer]

Hey all, I'm lars, from nz. I have a manual rd28 turbo y60, with a gt28rbb turbo in the side of it, I'm having a problem with finding out what vacuum pipes go where, especially for the diff locks? Can anyone post a pic or draw somthing? Specifically the 2x pipes down on the chassis which go to the rear diff, and the 2x solenoid pipes on the firewall. I cant figure out where etc these all go?

Thanks
Lars
