I've had some problems interpreting my Fuse Map for the Fuse Block #2 under the driver seat. I can be dense sometimes though. I think I've figured some things out. The listings on the right side refer to the relay rails under the seat cushion. The similar nomenclature on many of the listings can make it appear as though it is just repeating the same information.
To make things worse, on mine there seem to be some fuses which aren't identified at all. For example the three horizontal small fuses near the large 30 amp aren't called out at all on my list. I wrote the functions of those down in the lower right corner (SKREEM and ABS/CAB related). Some of the printing was getting light so I added the fuse values in ink pen (love that Southern description) before they go away completely. I then noticed what I thought was listed as 15A was actually 25A so it is corrected in the white blob.
It appears that the empty relay rail slot (for gray relays) in the picture below would be listed on the map as the "B" numbers on the right side of the fuse map if it is populated. Note the stamped "A" above the gray relays and faint "B" off the corner of the blue relay. Great labeling. The "A & B" appears to me to be more related to a specific relay position.
I post some of what I've learned here in case others may be foggy as I was,or perhaps people can add some more insight. I closed the thread to keep it on topic. FWIW. vic
My Fuse Map with some added notes.
My Fuse Block #2.
Note: The Fuel Pump OEM relay is likely an 87 style relay. My FP relay is an 87a style. Either 87 or 87a will work there just fine. Although the Starter Relay looks similar by the case style it is a special high capacity large blade relay style (same pinout as an 87 relay). It is difficult to remove. Be careful not to break anything as you gently rock or lever it out.
A 2002 Relay Block example of what the relays under the seat look like. Too lazy, too cold right now for an actual picture of my 2004.
A diagram from the book.
Another diagram from the book. Note: The red added info is for my very few options 2004. No power windows, no power locks, no remote mirrors. I have driver heated seat, A/C, booster heater, ... that's about it.
Added General Info
Vehicle Operation Terminals
Terminal 30 = Positive 12 volt battery constant Eg. - radio memory, ATC. Heater Blower
Terminal 15 = Positive 12 volt ignition key on
Terminal D+ = Positive 12 volt engine running (alternator charging)
Expansion/Aftermarket Terminals
Body Manufacturer Terminal 30 = Positive 12 volt battery constant
Body Manufacturer Terminal 15 = Positive 12 volt ignition key on
Body Manufacturer Terminal D+ = Positive 12 volt engine running (alternator charging)
