Instrument Cluster Pinouts needed

Thanks, Joe. I appreciate your help. To me, the drawings seem backward. The 91 pickup is a base model and only has a speedometer, water temperature, and fuel gauge. The two-part drawings only show the fuel and water (understandable because the speedometer on the 91 was cable driven). The other seems to better reflect the newer cluster (from a 95 Rodeo). It doesn’t show Enough.
I’m doing a motor swap project (5.3L LS) on my 91 pickup. I’m trying to integrate the Rodeo cluster into the work in order to get speedometer, water, oil pressure, tachometer, and battery into play. Wiring doesn’t quite match up in color or pin position on diagrams I’ve seen so far.
I appreciate your help. This site has dropped me out after several iterations of reply, so I’m sending a bit of a short summary. If you can come across other 95 Rodeo (94-97) diagrams, I’ll be much obliged.
Thanks.

Hey Joe, I have to say that this site’s propensity to wipe out my comments every time I select another tab is frustrating.
Anyway, the Rodeo is a 95 S, 3.2L, manual, with VIN 4S2CG58V7S4309065. I don’t know whether it’s a 95 or 95.5.
I know this sounds like a lot, but perhaps you could send the following:
Instrument Cluster - Early Production
Instrument Cluster - Late Production
Everything from the first pic since I’m not sure where the lines may cross within the connectors.
Again, your help is much appreciated.

Joe,

You may have hit gold (or, perhaps, "I may have hit gold."). The early diagrams seem to match up exactly with what I have for my cluster. My truck isn't at my house, so I'll head to where it is tomorrow to verify what I believe to be the right answer. I've generated a spreadsheet showing where the cluster's wires need to connect to the existing truck wiring. The rest will fall into the LS's PCM output for speed and tach. Water temperature should follow with what was there before as far as wiring. Oil pressure will be run separately.
Anyway, I'll keep you posted on how this goes. Thanks much for your help.

A couple of photos. It's a little further along than this seems, but still some way to go.
Again, I appreciate your help.

Hey Joe,

I'm back again with another question. Would you have schematics for the original '91 base truck's starting circuit? I have a pretty good look at the ignition switch, but the Chilton's manual just isn't as granular as I need (shows a blank circle for the switch, with some wires coming out - and those wire colors don't match).
As you can tell, this job is moving along at a glacial pace. I appreciate any help you can provide and understand if I've tapped the well dry.
Thanks.

Thanks a ton! Very helpful. Although I said I had a pretty good view of the ignition switch, that is a visual only. I've been ringing out the lines as best I can, but any actual info on where the following wires land would be much appreciated:
ACC
ON
OFF
There are four wires encircling the center post. I have the Start figured out thanks to this schematic you've sent. The others would be helpful, if possible.
Again, thanks much for your help.

Thanks again, Joe. I’ll check when I go to the truck tomorrow.

Hi Joe, here I come, hat in hand again, asking for more information. I'm in the midst of laying out the wiring harness and need to make a 2"-3" hole in the firewall (passenger side, close to centerline) and will have to remove the A/C evaporator in order to figure out where to put the hole. Then, I'll have to make sure there's space and run the part of the harness with the fuse block and PCM connectors. Is there any chance you'd have anything that describes the evaporator removal procedure? Thanks again.

Yes, unfortunately I am digging deeper than I ever imagined I’d have to. And the onion continues to be peeled. Would you have anything that speaks to removing the instrument panel? I already know how to remove the cluster, but if there’s anything that sheds light as to where the bolts/studs that hold these things (dashboard, heater core, evaporator box) together (along with, hopefully some instructions on how to access them in a sequential manner), I’ll be further in your debt.

Thanks a ton, Joe. I’ll let you know how this all fares out. I really appreciate your help.
