Question on tractor protection valve

[eddeere]

I never could get my old valve to work or stop leaking #227672. photo on left. Truck pro could not find anything on this part #. came up with a Bendix T.P. - 3DC. photo on right. The bendix manual shows where to plum everything up but the tractor protection switch in the cab. The only port left is the auxiliary supply which goes to the tractor supply port. Would it work here or is it needed as when the trailer supply line decreases to 20-30 psi closes the inlet valve. On the old valve the switch was connected to the fitting on the left. Thanks for any help.

Can't say if it will work or if you would have to change the dash control to make it work?

I replaced mine 15 yr ago, it failed a few years back(started to leak). I fellow from PA gave me an extra one he had. Someone on JOT was looking for something similar and found a handful on Ebay. There were in Akron, Ohio to boot. I'm trying to find the post/link.

Found this on Ebay: not sure if right one.

I think these were the ones I was thinking of:

Thanks Larry. You are correct I would have to change the valves in the dash to make the TP-3 work. The second link you gave me is exactly like my old one with a different part # ? I plan to get one of those.
