Continuing 84-88 Instrument Cluster/ Ignition/ Headlight switch wiring questions/ Help requested....

[HadASplash/XLTSC]

I'm looking for a schematic or a pin-out sheet for the two connectors that go into an 88 Ranger STX (Bronco II) factory instrument cluster.
I have the 88 Ford Factory Electrical/Vaccum Troubleshooting guide but it does not list / diagram the Gray & Brown connectors that goto the Printed Circuit Ribbon on the back of the factory gauge cluster. I'm finishing the install of a Jeg's GM to Ford Engine swap Complete wiring harness but having trouble mating up the cluster....

Okay- Thank you! If anyone hasa little more info, these are the last wires we need to identify/connect in the almost complete install of the new Jegs harness.

The biggest issue we have right now is just a few unidentified wires...Especially the heavy gauge Red/Lt Green wire in the photo across from the double Red/Yellow...(Photo 0515)

Also we need to identify the following from the Ignition switch (photo 0514) and the Clutch Interlock plug (Photo 0512) as well. Please see the photos below...

What is the source for the Tachometer "L2" feed (Photo 0511) as well, please?

Tachometer signal would've come from coil originally.
The only Red/Lt Green I see in the Haynes/Chilton diagram is labeled hot in run 15A.
The two Red/Lt Blue on the clutch switch are from ignition to starter relay. There is a Black/White (from computer) and White/Black (to computer) so it knows you're in neutral. (The same 2 wires are split through both switches so either one activates the computer.) The 2 unstriped Light Green wires are for cruise control. (

Thanks for the help! - No Computer as it has a carbuerated 80 Buick Turbo v6 so I can deadend the Greens and Black/white & White/black
