I have installed M&G on my 85 Cherokee Diesel, 05 Jeep Liberty Diesel, 06 GMC Duramax Quad Cab, 07 Jeep Commander, 08 Jeep Grand Cherokee Diesel.  The two, last mentioned were complex installs.  Like moving fuse box and altering shock tower.  Great setup and good people to deal with.  I am looking to tap into my air system on my 88 single screw Newell.  (#174)  Any suggestions.  I removed what looks like a 1/2 inch NPT Plug from the control box above the drive axle and air dashed out, so I assumed it to be wrong hole to play on.  Someone suggested a tee in the service brake line.  Any idea on what tee this would be and where one might get one.   Thanks    Pete    Florida
