Well.....
No real progress yesterday.
We narrowed our fuse blowing issue to the reverse lights being sent to he wrong blue line. Without those connected the truck operates well.
We still couldn’t get 4WD to engage. I can move the transfer case between high snd low so the internal shift fork isn’t my issue (thank god since that would mean dropping the assembly and opening up the case again

)
Driving it home last night I noticed a high idle and stumbling when engaging the brakes at a stoplight. I have a feeling we screwed up the vacuum lines going into the vacuum activator on the transfer case when we dropped it out for the swap. If that, in fact is the caee, our 4wd issue lies there.
We did test both solenoids and they are good.
We did fry a wire during our botched firdt wiring attempt snd its possible that I injured the transmission switch, have a new one in route in case the vacuum fix doesnt woek.
On the bright side....love having a stick shift again! The gears are certainly low and on flat terrain 2nd gear is the preferred start up plan (as noted by many others). I run stock tires, if I ever go bigger the ratios will be perfect.
Lots of work, lots of happiness, lots of frustration. All worth it.
Hopefully and update in a day or so.
