89 comanche eliminator

[dj5]

I'm new to the forum but I just bought a 89 Comanche eliminator for $900 that is rust free and supposedly had a rebuilt motor but 141k on body.
truck had no keys and didn't run, he said it was a father son project but his son was deployed to the marine corps. he was under the impression that they blew the ecm. I towed it home and put in a battery and a cps as well as a lock cylinder and fired up, he screwed up a bunch of wires and emission hoses, so capped off emissions and working on wiring still.
speedo doesn't work and rpm gauge is way off ( idles under 0 but revs up when I push the pedal) and all other gauges work.
no turn signals and ac was rigged up to a switch under the hood :doh: 

fan in engine bay does not work either and egr seems to be smashed.

what do you guys think could fix speedo and rpm problems as well as turn signals?  maybe just a new cluster? :crossfingers:

 

 

Thanks
. :MJ 1: .

 

btw will post pics when i can get some uploaded

Speedo is run by a cable from the output on trans or tcase if 4x4. See if it's hooked up first. As for other problems your going to need to start figuring out what the PO has rigged up.

forgot to put its 2wd.
the guy I got it from didnt know what he was doing, the cps was there but he smashed it and cut the wires, as for the ac that was rigged he said it was like that when he got it but he said his son knows more...who got deployed :???:

he left about 20-30 pages of wiring diagrams on the seat said he hadn't touched it in about 6 months
