Sorry Bert to not get back earlier--I do NOT have power at the round flasher pin (with ignition 'on' as you stated). I'm confused (obviously) about the turn signal flasher vs. the emergency flasher--the latter SOUNDS like it is mounted behind the glove box, but can't see. I thought they were one in the same, but with the ROUND one unplugged (in fuse block with other fuses) to check for power, emergency flasher switch pulled out, emergency flashers only work, but no power at the 'turn signal flasher' unit, but there IS power on fuse #5 (for turn).
I think I need to clarify that I've posted this in the 'other' Ford forum, that of which you already know. I think it best to close this one off as Bert and other are contributing there, focusing on the wiring of the steering column and the 'turn signal switch' ("C305" as I've found). Is that best?
Thanks to those that chimed in here; the other posts can be found:
