Send me your real address to
cewhite3@mindspring.com and I will send the
manual to you. You could also try
https://www.fleet.ford.com/maintenan...ls/default.asp or go in
through the motorcraft front page -
http://www.motorcraftservice.com/vdi...il/default.asp and then click on
the "Owner Information" link on the left side of the page.
Item 15 is a 50A Maxi Fuse for the Air Suspension Solid State Compressor
Relay. It is the 5th fuse from the left on the front row. I am calling the
row of relays the back row. The 2 x 6 group of smaller fuses is in the
front right corner (these are fuses 1 through 12 - the larger fuses in this
line are number from 13 to 19 as you move right to left.
There are other fuses related to the air suspension. Fuse 4 is for the Air
Suspension Service switch (4 is the second switch from the right on the
second row of little fuses from the front). Here is a crude layout -
