The dummy and the diesel.........The Grey Whale

Yesterday I spent under 20 bux and ordered a pneumatic solenoid valve off egag. This is to modify the front axle disconnect (vacuum) which is controlled by a switching valve on the transfer case. BECAUSE of the OEM valve, the axle / drive shaft is not turning, and you can NOT engage 4WD while moving. This solenoid and a switch/ wiring will allow me to "lock" the front axle active similar to "locking in hubs" on a slick winter day

Then all I need to engage 4WD is "grab the lever"
