On both my 77 and 93 coach I was able to tap into an unused port in the rear axle brake relay valve mounted above the rear axle. Yup, on the 77 that plug was TIGHT. I don't recall how I got it loose.

Pete you might want to repost your M&G brake question separately - it is probably getting lost in this thread...

Thanks All. Rebuilt solenoid and installed it today. Works great but, panel really slams open and shut. I installed a 1/4 inch pipe plug in one exhaust port with a 3/32" hole to slow down the escaping air. I guess this was too large because it is the same. Will experiment with a small valve to see if I can quiet down the operation. Pete

Since the most recent post in this thread is going on a year old, here's an update. The air solenoid that operates my curbside dump valve is an AR0, P/N: A212SD – 012 – D. I called Fluid Handling Dynamics, talked to a guy by the name of Nick, 419–633–0560. He confirmed with me that the current part number, as Tom has listed earlier in this thread, is 118597–12. $117 for the whole solenoid, $32.60 for the rebuild kit. I ordered the rebuild kit. ?
