        IMHO the +12v wire to the power steering pump idle boost switch is

the Most Necessary Wire In Need Of Fuse!!! If it happens to Fall Off due to

vibration or get Blown Off by water pressure during an Eng Cleaning & then

makes contact with Ground, the result will be a Fried Eng area Wire Harness

& those Are Not Easy to Find or Replace ~
