Replaced signal flasher, truck stays on (possibly haunted?)

Hey folks, had kind of a weird thing happen and thought I'd run it by you. 1989 2wd 4.0 5 speed base, been learning a whole lot since I bought the ole Comanche last year (has a few electrical quirks but nothing too major). A few weeks ago my turn signals quit working and the hazards would come on but not blink. Did some research and poked around a little bit, pulled the little pot flasher for about the fifth time and when I plugged it back in, everything was good. Then about two days ago my blinkers went out again.

 

Swung by the parts store in town to get a new flasher, figured it wouldn't hurt since I needed to check on the damn side marker cover I ordered last week (turned out that was delivered on time just to a random address 2,000 miles north of me). No big deal, sorted that out. Went outside and put my new flasher in, voila, got me some indicators.

 

Drove about 1/8 of a mile to the house and shut off the truck and damned if the thing didn't stay running. Pulled the key out and it just hummed along. Finally stalled it to get it to shut off but all the dash lights stayed lit. Restarted it and it did the same thing, even revved up real high for a minute for some reason. I looked at the fuse block to see if I'd done something and when I wiggled the little ignition wire it shut off and now it seems fine. Starts and shuts off like it oughta, no exorcism required.

 

I guess my question is what the hell? I don't think I bumped anything putting that new flasher in but I suppose it's possible. Or is it something more complicated I should be on the lookout for?

 

Did a fair bit of research before posting but it seemed so weird that I'd have a brand new issue seconds after changing that flasher, and I'm pretty confident I didn't do anything unusual when I changed it.

 

Thanks everybody.
