7.3 IDI won't start...

[445TDF-series]

Need my 92 7.3 for work earlier than expected tomorrow. Was in working on the truck's harness removing the old glow plug controller and plugged it back in and the truck won't start. Has manual glow plugs. IP doesn't click if i remove the little top terminal like it used to... no blown fuses. Am I ok if i wire a switch in to the top terminal and to the battery? Would running 12v straight off the battery cause problems?? It would be on a switch so for shut down I'd click the switch. thats all i can think of to do....any help would be greatly apprecited!!

there is a fuse in the panel under thye hood that feeds the pump.
see if ya have 12 volts at the pump, if ya do, sounds like the seloniod is bad, if ya dont have 12v at the pump, ya can hook it straight to 12v and it should work.

all fuses underhood look good. My multimeter is on the fritz so I can't test it that way. I'll hook a test light to it....

FIXED. The harness had really bad corrosion in the main connector on the fender... Everything worked except the pump... thanks for the suggestions though.
