Thx for the info, I'll look into it later in the week when it warms up a little.

Starting to get a little cool in Jersey

Dick this is what my FRB looks like along with the label explaining what’s there. I don’t have DRL’s just fog lights

Thx , 

I look forward to your reply.

BTW I,ll need to know what relay to remove

I know this has been addressed before and I apologize for asking but I can’t find the answer.

I want to get my fog lights to work without the headlights being on.

I think a relay had to be jumped or a wire swapped in the front relay bay of my ‘99 Windsor.

I’d really appreciate any help someone could offer.

Thx

Dan

Thanks for your input, the mac valve is located on the firewall above the genset.

No worries about crawling under the rig.  Still having a hard time locating the mac valve (is it discontinued?

Pulled all the hoses off and sprayed ports.  Don't know if it helped Has anyone had experience with substituting a Humphery Valve.

Again The mac valve is a 4 port unit 45A-AA2-DDCA-1BA.   And the Humphrey Valve D1052 from NWRV Supply.

Thx,

My step cover mac vale leaks from the exhaust port when the pressure @ 120 PSI.

After shutting down the rig the pressure drops (from the leak) and @ 60 PSI it stops.

The mac valve is a 4 port unit 45A-AA2-DDCA-1BA. I've been told the it can be replaced with

a Humphrey Valve D1052 from NWRV Supply. Has anyone had experience with this valve.

If so, I need a hookup diagram.  As far as I can tell, it doesn't have an exhaust port.  Do I need 

that port.
