A Google search netted this:

There is an overdrive solenoid inside the transmission that kicks the OD in and out with the switch. You could have a bad wire somewhere or solenoid is bad.

Any shop that performs smog inspections will have that info.

If your alternator tests good off of the vehicle, but will not charge on the truck you need to make sure that the supply wire has 12V and that the field is also getting 12V. If you track it down to the ECU you can save yourself a bunch of money by having an external voltage regulator wired in and bypass the internal ECU regulator.

-If it has Distributor Cap and Rotor check them and their contact point should not be rusty, cut/worn. Rotate Distributor assly for getting a better synchronization/timing.
- check you have fuel pressure at fuel rail.
- is the fuel fresh. Spray some starting fluid in the air intake. If it starts up then problem is with fuel.

can you just try this, remove gas tank cap and go for a run with it off, see if its any better. if you can put one of them fake gas tank caps on with the filters, if it runs better then the breather in the cap is blocked. or the breather for the tank is blocked.

Doesn't sound like the transmission. Your cable is probably stretched out and needs to be replaced. Yes, you can take out the cluster in less than 20 minutes

check the obvious
bad ground wire from the battery, loose battery terminals

the idle mixture screws are only for mixture adjustment at idle
at speed the idle circuit acts as a emulsifier tube to help with the fuel in the main jet
what you need is adjustable main jets or fixed jets for that altitude
talk with an accredited carby overhaul shop that knows about the carby you have fitted and the appropriate jets to use

If you have access to a multimeter check the power terminal. It should be at least 13+ volts if the alternator is good while the car is running. The battery will not maintain more then generally 12 volts while the vehicle is off. Be careful not to drain the battery to far as it will damage it.

Not difficult it's part of your positive wires inbound to dash... It's easy to rewire just be patient and find where the wires go/where they come from... The white wires are hot aka positive but all others are color coordinated in I'd say 8-9 colors. Most wires change colors from the cab back or cab to engine compartment and some are a pain by going into old school 1 to 3 wire connections. If you can't find it still or its missing pieces look up a junk yard and grab another couple used pieces for it. Also look at your light switch, bright light switch or grounds to even your tail lights... Sometimes even a stray branch on a back road will rip a wire loose if it's old and brittle

tail lights check the earths at the back and fuse

if you have parkers and headlights
no dash lights is wired
could be the switch or fuse

Are you getting spark? You've put a 2001 engine into a 1986 body. The 2001 engine ran with an engine control module (ECM), the 1986 doesn't have that. The 1986 probably has an electronic ignition module that works with the 1986 coil and 1986 reluctor/distributor. You may want to compare the two distributors and the two coils.
