This is my version of BlankDeluxe's minimal wiring harness.
disclaimer: This is for either a manual or an aw4 with a tcu delete.
I started by pulling the whole harness out where I spread everything out into basically a rats nest. Figured out what I needed to keep:
CPS/engine speed sensor
TPS
Cam/sync sensor
MAP
IAT
Injectors 1-6
ASD (B+latch) relay
IAC servo/motor
CTS (In the side of block)
Knock sensor (not critical)
O2 sensor (not critical)
Fuel Pump Relay (moved to a switch)
I then cut out pretty much every unnecessary wire. replaced most of the wiring, make sure to give yourself 6~inches past the plug in case any crimps fail.
I did remove the wiring for the O2 sensor heater because I don't care too much about wether or not that reads correctly.
I included the B+latch relay because from what I've read it is required for the motor to run, but it isn't really connected to anything anymore.
The "start switch" note I added is incorrect. it should be the run switch/ignition power
Starter solanoid is just wired to a button
I will post some more pictures this afternoon or tomrrow when I get everything finalized.
