Decided to do some work on the wagon since I experienced a massive battery draw that killed it in a few days a sitting, something it hasn't done before. It only happened after I disturbed the relays, which had a tendency to self trigger if bumped or shaken, and of course it's the important ones for the EEC and Fuel Pump.
After determining that, the next best step was to modernize, using a '90+ relay holder which uses conventional five pin cube relays versus the odd ball five pin, non-cube type ones that were originally fitted. It also gets a circuit safety feature too, a diode for the EEC power circuit. I also get to use a newer style vacuum box, versus the coffee can. I did make a mistake in attempting to use a '95+ vacuum box and holder assembly, when a '90-'94 one works better. Luckily I had the old style vacuum box for these cars, so I've just got to get the right holder, since the '95+ one sits up too high, but locks into place.

Now I don't have random self-energizing relays causing trouble for me. Plus, should I ever have a relay fail (all of the ones in the holder were factory Ford OE ones), it'll be much easier to get one since it's a common type, versus the more unique originals.
Maybe the next job will be using an proper fuse box over by the starter solenoid. Ford used a bunch of fusible links off the starter solenoid, so it's a rat's nest on that fender. A fuse box from a '90-'94 Town Car would be suitable as the links would be replaced with proper fuses and the horn and air shock relays could be re-fitted into that box.
