ESOF electrical

I replaced my ford auto/manual hubs this summer with superwinch manual lock hubs. I used 4x4 for the first time yesterday, and shortly after switching to 4x4 high, my heater switched from vent to defrost. I obviously have a vacuum leak somewhere on the hub system. Since I no longer need vacuum to the hubs, I'd like to electrically disable it. I discovered under dash fuse 28 also powers the vacuum pump motor and cruise control and stuff, so I can't remove it. Under hood fuse 17 also powers the transfer case motor, so I can't remove that either. Will removing relays 40 and 41 cause any problems? Do these power anything else? Will I get any trouble codes? All I want is to keep the valve from actuating and pulling vacuum on the hubs.

I dug a little deeper, and I think the relays control the transfer case. Anyone know the electrical for this system?

I'm with you on this as I'm getting ready to install manual hubs on mine. I was going to ask the exact same question. Somebody has got to know?

Not sure if this will help, but it seems to me the lines to the old vac hubs are probably just open to air now.

Try plugging those old lines?

It seems as though there is no way to do it besides unplugging the valve itself. I don't really want the connector just hanging out exposed, so I think I'll just disconnect and plug the vacuum line

You should be able to just unplug the electrical connector to the PVH solenoid (this is the solenoid that sends vacuum to the front hubs). This way it won't matter if you plug the vacuum lines or not because there will not be any vacuum going to them at all.

Here is the location of the solenoid:
