Probably same spec as BenJ's EBI Fairmont Ghia wagon.
Likely if the door ajar wiring is in all doors.
Sounds like the dash and some of the body wiring has been butchered, EF/EL added in.
Bit of a shame, as adding Fairlane bits (cluster, etc) would've been easier if all the wiring was in place.

True, I didn't get a chance to look at it today. I am fighting off the flu and figured I was better off in bed than outside in the drizzley rain and wind pulling my hair out.
Won't be too critical about the conversion, it's growing on me. But I haven't seen much of the wiring conversion under the dash yet, I did find a few joins in the loom that were taped up with that brown packing tape
Anyway, weather is suppose to be better tomorrow, get the fathers day thing over with before lunch and then I can spend the afternoon tinkering with the cars......now that's what I would prefer to be doing on fathers day

I recon you got broken wire somewhere between door and body (usual place for broken wire).
I faced these problems before and not only on Fords. If you will remove drivers kick panel you will found the connector plug behind it (and behind insulation as well). Check circuit continuity from indoor connectors to body plug connectors and you probably will find broken wire. It’s not that big deal to put additional wire through the door, cut existing broken wire closer to plugs and solder in new one.

Thanks Peter, it's all sorted now. You were right though, once I removed the kick panel and found the connector, it made life a lot easier belling out the cables. All working and I taped up most of the loom to tidy it up, so it should be good for a while.....
here lies the problem

should last a bit longer now

also tidied up a bit of the loom as well and resoldered all joins for the window motor, just in case
before I taped up the loom

and for the interest of others who may have a similar problem in the future, here's a couple of the connector between the body and door looms


and yes, I cleaned up the oxidation on the terminals

Also traced the problem with the electric lock to a faulty connector, it would work intermittently if you put pressure on the plug to one side and held your tongue out to the opposite side , but because the plugs were sealed, I just cut it out and replaced it with boot lace crimps and a terminal block (temporary measure) until I can steal one from the LTD (I know, there is a reason the connectors are sealed)



Oh, and thanks to everyone who did offer assistance, your help is always appreciated
Cheers,
