Tapping into the service brake line

[SilverBlivit]

I have installed a M & G onto my 06 Nissan Titan and am now ready to tie into the Coach Service Brake line. Problem is: I have no experience w/air brake repair/maintenance. I know one is Service and one is Park/emergency. Is there a good, quick, sure way to know where to tap in a 0.25" line to go to the M & G?

I didn't know either but did it anyway...had a 50/50 chance of getting it right..then when I added some intuitive guess work/elimination, came to 100%! There are 2 ports on the air manifold block near the rear axle...one is for the service brakes (the one you want) and the other for the emergency brake....On my Spartan they were actually marked on the air manifold block and there was an extra unused port on that side where I removed the factory installed plug and added the air line connection...very easy to do except that I really didn't like being under 20 tons of stuff

When I installed my Roadmaster system I could not tell which air line was which. I called my local CW to see if they could help me out and they gave me a couple hints and I was still uncomfortable as to which one to tap into so after calling them again for a little more info I asked them how much $$to install the valve and line on the coach. They quoted $75.00 so needless to say I drove the 20 minutes to CW and had them do it right the first time.

Captain, that is sage advise, but I decided on the DIY path!

Monty @ M & G talked me through the discovery process and all is tapped in and checked. Can't say enough for M & G. I would recommend working with them to anyone.

Anyone wanting to install M & G into Nissan Titan product PM me, I will gladly share my discovery journey and learning curve. At the end of the day, it was not all that difficult, but for the un-initiated it is certainly a foreboding discovery/decision pathway. There are obstacles but they are not insurmountable, nor particularly difficult....just up front, in your face, and intimidating.
