    brown-ish should be ECM... green fuel pump... white AC/WOT cutout relay... IIRC. If you need one known good and it's those stupid Ford only relays (not the universal Bosch style) I have the original from the 88 MGM I had.

    One half is brownish or tan, the other half of it is black. It's smaller than all the others, which are green. Not sure about what lives on the driver's side firewall. I wonder if that thing going wonky has caused the ECM to smoke itself.

    Could you post pics of that bad Jackson by Friday or so?

    I agree that any type of contact (short of unplugging it) should not cause the relay to chatter at all.
    Keep in mind that upon the ECM powering up, it will trigger the fuel pump relay, so both will click at first power on, this will magnify your perception of what is clicking and why.

    I have pretty abusively manhandled my relays on the Townie when running and get nothing like that.

    I would very carefully inspect the wiring. An intermittent wiring break that only seems to surface during wiggling would not be unlikely. Loose terminals in the relay socket could do it too. They can be unlatched and pulled out, then you could tighten their contacts somewhat and hit them with some contact cleaner. Be sure to do this one wire at a time so you don't lose track of which contact they belong to.

    You could say that again. Application-specific relays with keyed bases so you can't even swap them in place of each other.

    I believe the aftermarket produces a "Ford universal" type relay that fits all of the weird Ford socket keyings as well.

    I can't remember which one is the ECM relay on these, but if you touch it and the engine goes retarded, obviously something is wrong with it or the wiring to it.

    Yes. Aftermarket ones are available... and about as good as the "40A" relays in the stick-ons section of Autozone.

    I need a damn EVTM manual for one of these things. It's killing me. I'll look for one today.

    When I unplugged those relays the contacts didn't look rusty on either the harness or the relay, so I suspect it's as the Kishman pointed out.

    LoL no swapping here, engine runs fine it's just the fuel/ignition management that seems to be suspect. However, if it turns out to be something like timing chain slop I guess we'll just drive it until it doesn't want to drive any more. I don't want to give up on the thing but then that's my problem, I get attached to cars I shouldn't get attached to haha.
