87 YJ gauge cluster wiring diagram

I have an 87 YJ that I am trying to change out the gauges with digital ones, but I am needing a wiring diagram. Does anyone have one they can download. I also need the diagram for the speedometer and tachometer.

I do have a PDF called: Jeep YJ FSM Wiring diagrams. It must have been put together by someone, and I don't know where I got it. But it does have the '87 dash schematics. Just not the speedometer, I think because it was mechanical in '87. It has info all the way up to '94. So maybe you can use a newer model speedo schematic. PM me if you would like it.

When I see the price of OEM I think aftermarket.

This is what mine were on my '90. Disregard the pin #'s as though are where I put them in a 12 pin Molex connector and the gauge color is what I ran in my home built harness. The speedo only has a cable and lights, the tach should be very clear once you pull the gauge.

I can't even read that. I can barely read the one I have. But here it is.

If you're having trouble reading that, PM me for the link. It's easier to read in PDF form.
