'99 Hoe throwing P0107 code

[gunrunner]

It has been an ongoing battle to get the bugs worked out of my 99 Hoe. After changing everything on the fuel system, it still acts like its starving for fuel. I managed to track down a code reader, and it pulled a P0107 (MAP/BARO Circuit Low Input). I checked the 5 V reference circuit that feeds power into the MAP sensor, and the best it will read on my VOM is 0.18V. That is a serious voltage deficit. So I figured the problem is either with the PCU (computer) or wiring. I checked the fuse box under the hood (missing lid since I bought it), and man, are the fuses nasty. All check good with my VOM, but the legs of the fuses are all corroded. Anyone have a good diagram of the fuse panel, and any ideas on how to clean the contacts in the fuse panel?

Any input would be greatly appreciated,
