Cluster Swap not working
I have an 86 F520, with a 5.8 and an auto tranny. It came to me free, "well used," and without a factory tachometer. I lucked out in the junkyard today, and found an 86 F150 with the factory tach. I did a search on the cluster swap topic, and from all that I read, it should just be a plug in and go deal. However, I hooked it all up and the tach didn't work. Obviously, the PO had done a little electrical wiring of his own in the engine compartment.
So my question is this: What needs to be connected to the coil in order for the tach to work with the factory wiring? My Haynes and Chiltons wiring diagrams are useless, and none of the "extra" wires seem to be it.
Thanks in advance, Frank

It does have factory guages, but the PO did some wiring of his own on the coil, and I had to do some of my own to even get it running. I'm wondering what the original wiring to the coil was supposed to look like, as I can't find a lead going to the tach anywhere.

My 83 Electrical manual shows both the Duraspark and EEC the same, so it sounds like a common hookup....one lead off the coil goes to the ignition switch, the other goes to the computer (with a connector midstream running to the tach).

From the "Tach" (-) terminal on the coil trace the Dark Green with Yellow Dots (DG/Y D) wire to connector C311 and to the Ignition Module. From C311 a DG/Y D wire should go directly to the Instrument Cluster connector supplying ignition pulses to the Tachometer.
