Picked up the Mallory fuel pressure regulator that I should have gotten in the first place. Haven't had time to install it yet. Heading out of town this weekend and won't get back on it until next week.
Wanted to write out a list of what's left to try and think this all through.
Here's what's not hooked up on the electrical/wiring side:
-diagnostic port: have wires IDed in harness, just need to locate it and wire it in
-MIL light: this will be fun. needs to come out of the circuitboards from the back of the gauge cluster... details in different threads on cjoffroad.com, need more research. since I don't have emissions, may not want to bother.
-O2 sensors: when exhaust goes in. debating on #2, don't want to spend on a catalytic converter.
-fuel level sensor wire: 100 ohm resistor will give needed signal to computer, may trip an occasional code for not using enough gas to travel some given distance, I don't care about that as long as it's not constant and it shouldn't be. I was wondering about a way to wire up a circuit that would decrease resistance over time in the range that the sensor looks for... seems like it could be done but I just don't care enough to try.
-battery temp sensor wire: another 100 ohm resistor to fool the computer, simple)
-tachometer: think I just have to splice into the coil + wire
-VSS- need to install Hesco 2-wire connector on the stock 3-wire setup, need research, connect to Hesco VSS/spedo unit
-voltmeter: it seems to be reading, but there was a wire that went to the alternator plug that's an odd single-strand black wire that I thought was the feed to the alternator... its currently not connected. Need to look that dealio up to see what needs to happen there. (anyone know?)
-OBA: last on the list, need to source a tank cheap anyway, have relay feed pulled to hook to switch and was planning on reusing stock high pressure switch.
-I have a few wires that I IDed from the FSM and kept, but I don't know their function or how it relates to the computer running. Need to find out about those and thin/connect as needed.
Mechanical things not hooked up or needed
-tcase/driveshafts, ready to bolt in, won't clock it at this time.
-fenders/grille/radiator/headlights/etc: need to locate computer, might be on top of driver's fender by the looks of things.
-fuel pressure regulator
-fill/burp coolant system
-plumb in tranny cooler lines
-bleed power steering
-reinstall and/or secure all vent fittings
-fab tranny shifter link: looks like something can be made to work off of my stock floor shifter

I really wanted to keep that unique feature of the postal
-twin stick install: FINALLY had all the parts made sitting on the shelf for a couple years
-reinstall winch
I think that's it. Major hurdle now is the exhaust. The rest I can just plug away at...
Hope this all is of some use to folks!
