yes it comes out, but it needs to be there
Diode makes sure power can only flow one direction
The EEC fuse is for the EEC relay and basically this powers up the trucks computer when you turn the key to on The eec fuse and relay are located in the under hood fuse box
You turn the key to on the ignition switch in your steering column sends power to the eec relay. The eec relay then clicks on and powers up the trucks engine computer (eec or pcm)
The 4x4 electronic shift computer in 94 is independent of EEC system and is fed by the 15 amp fuse circled earlier in from the interior fuse panel
