Help plumbing up air dryer on w900

I bought a 95 w900 with a 3406, the air dryer is not hooked into the air system. It will build air up to about 150psi and then continuously bleed air off one of the air tanks. Currently there are no hoses hooked to the dryer, and it looks like one 1/4 inch line that is supposed to be going to the dryer is broke at the fitting and is hissing also. As far as I can tell, the cut in and cut out pressure is ok on the governor but I've never had to mess with too many air system issues.
Can someone give me a basic route of where the two small lines go from the governor and also where the main outlet of the compressor goes to first etc?? Thanks in advance

 

Yea it's definitely blowing a safety valve every couple seconds once it gets to 150psi. I guess I'm saying the governor is ok because that broken 1/4 inch line starts hissing around 120psi. There is a larger line, the same size of the main outlet line, that appears to be unhooked and bypassing the dryer if that makes any sense. Can't imagine why this was all done like this, like I said, there are no lines attached to the dryer right now lol. I think I'm going to just run two new lines from the governor to the dryer and separate the big hose and hook each end to the dryer and see what happens

 

I put a new Bendix AD9 on last night. It purges at 120psi and also lets out one snort when the governor kicks back in at 95psi or so I guess that is ok now.
Once the dryer purges at 120 though, it will start sh sh sh air out the purge exhaust until the governor kicks the compressor back in at 95, then the sh sh sh stops. There is no leakage at the purge exhaust when the comp is building air.
I've found conflicting info on the troubleshooting pages. Some say the AD9 will sh sh sh for 30-40 seconds as part of the purge cycle. Some say my unloader is causing the comp to keep building air but it's not building air after purge.

 

Got it all fixed up, i put a new unloader valve kit in the compressor and all is well with the new dryer
