Darn.New 1991 RT4WD and it died- under dash wiring mess!

Band Wagon
Hello all...
Monday I bought a super nice 1991 RT4WD wagon with 118,000 miles and ice cold air, new auto tranny and dizzy. I've put about 100 miles on it. The only issue I've noticed is the driver door hinge is wonky and sometimes if not closed softly the auto seatbelts don't work...
Well anyway today I am driving about 20mpg and the RPMs drop to 0 and jump to idle, drop to 0, jump to idle and the car dies. I push it outta the way after I determine it isn't gonna start and after some cussing, have a looksee.
When turning the key to start, I can't hear the fuel pump. It cranks.
My last Honda [a 1997 accord] had an issue with the starter switch in the key assy., and so I decided to take the under dash panel out.
MAN!!! There is a kill switch in there [doesn't seem to do anything], a buncha wires that don't go to anything anymore, a red and orange wire that seem to be cut, and look like they should go to the center of the fuse box, stuff is spliced to a red/wht 12ga wire, there are like 22ga wires spliced in to things all over, a BIG connector that's not plugged in to anything, and it's basically a mess. I am pretty sure that's where the problem lies.
I guess what I am asking is: does anyone have a pic of the underside of the dash with both the plastic and metal panels off, and/or a pic of the underdash fuse box. I have a diagram but it's not much help thus far.. also if anyone has instructions for wiring in a kill switch that I could work backwards from...

ECU throws no codes
Seems to be no spark - crammed a wire in the boot and had an assistant hold against the groundpoint on the valvecover
The nuts on the grounds on the valve cover are spakin new
There was an alarm & carphone installed, and the wiring is cheese under the dash....
The main relay seems to have been moved
There is a whole wiring harness that is totally unconnected to anything under there, it has as inline fuse...
And it won't start... Fuel pump primes though...
OK, fuel pump fires
main relay clicks
seems to be no spark.
On the under-dash fuse-box, there are terminals labeled 3 4 5 with spade connectors on them
#3 has an orange wire that goes to nothing connected to it
#4 nothing
#5 has a red wire that goes to nothing connected to it.
If I touch #3 and #5 I hear a loud relay somewhere under the radio click
The under-dash ground near the left driver knee area is connected to nothing
There was an old alarm break sensor and some other crap like a relay with 4 terminals and a socket and a diode wired in, a kill switch of some sort, etc I removed everything that I know didn't beloing. There were wires spliced in on the WHT-RED wire and the WHT-BLK wire, and the BLK-WHT wire had been cut and had all sorta crap spliced in. They now just go to themselves.
There is a zip-tie around a BLUE-GREY and another tiny thin wire in one of the harnesses that was all taped up weird, like it was noting something, but nothing seems cut.
And the big mess... There is a whole BIG plug plugged in to.... nothing! right by the left foot, driver side.
It says ACX 07B on it, and PN 1502-0092 and the wires comming out, in order are:
BLK-WHT, ORANGE, PURPLE, GREY, BLK, GRN, YEL, BROWN, WHT-BLK, WHT, RED-WHT, RED
and there is a buncha wires taped in a bundle hooked to nothing as well [some of them were hooked in to the alarm and relay crap] the are colored:
GREEN, GREY, BLK, BROWN-ISH GREY, RED, ORANGE, YELLOW, BLK-WHT
Tomarrow morning if my car is still there [dead in a bad part of St. Louis city....] I'm gonna check the dizzy... It's a new one, supposedly, and looks it, not just the cap either... But I suppose the rotor could be off....
HELP!!!!
Honda are very nice to us with wiring.
I've seen (unfortunately owned) some French crap which has a single colour wire through the car with different patterns in primary colours on the ends which just wear off!
