Explorer - Could we go back to your post #5? I was working w/Chris to fix the many mistakes in my posts and reread your post. What caught my eye this time was these statements:
On the 1980-1982 the dimming circut uses a dimable backlight that is controlled with the headlamp switches instrument cluster dimmer. It is the same circut that lights, controls and dims the instrument cluster. (Light Blue/Red Stripe) On this clock you can adjust how much the lamp dims, although it only dims slightly more.
The 1983-1986 clock uses the brown wire (which is the same as the parking and tail lamps) to dim the backlight. (On this clock the lamp is either full bright or full dim).
But, in the picture of the schematic, which matches my '81 FSM, those early versions of the clock had brown from the lighting, not light blue/red. Is there any chance that you had it the wrong way round? IOW, the later ones had the blue/red and the older ones had brown? I only ask to get this thread right for future use.

Glad you asked, Gary! Thank you! 
I'd prefer everybody ask outright if they see something they thing might be wrong.
I've been wrong plenty of times and will be wrong again, just wait and see.

Here it is... 1980 diagram: 1981-1982 virtually identical.

How sure are you that the color really was brown? What was the abbreviation for the color? Br can easily be mistaken for Brown when it could also mean Blue/Red. I've found quite a few mistakes like this in my Hayne's diagarams where they mislabeled or incompletely labeled a color.

I've gotten lazy and usually only take digital pictures of things anymore cuz it's faster & easier than firing up the scanner.
Scanner does a better job and maybe "someday" I'll make it less of a PITA but for right now, this is what I'm doing.
Anyhow, this is from the 1981 wiring diagram; as 81 says, yes, virtually identical.
Virtually the same stuff as what 81 posted, but....What I want to point out is the clock's connector in the top-right corner, which also lists a LB/R wire on the connector of the clock itself.
It's a somewhat large picture (2238 x 1320) your browser might shrink it on you, might have to click on it or sumthin' to see it full size.

Now, THAT is a really good possibility!!!!!
So, Gary.... Can you post a pic of this FSM of which you speak?

Read thru all these posts, was kinda surprised that no one asked if any NOS clocks were available, so I thought I'd volunteer the info.
E1TZ-15A000-A .. Clock Kit-Electronic / Includes wire and instruction sheet / Obsolete
1980/82 F100/350 & Bronco / No Ford Dealer or obsolete parts vendor has any.
----------------------------------------------------------------------------
E3TZ-15A000-B .. Clock Kit-Electronic ~ DATE - E/T - TIME / Includes wire and instruction sheet / Obsolete
1983/86 F100/350 & Bronco.
TISON MOTOR CO. in Estill SC has ONE = 803-625-2551.
B. F. WHITE MOTOR CO. in Stanton TX has ONE = 800-953-3321.
Make sure it's E3TZ-B .. cuz A is for a Ranger.

Ok, having gotten to a real computer where I can actually see the diagrams, as opposed to looking at them on an iPhone, I admit, once again, I erred. 
Apparently I overlooked the difference between BR, clearly meaning Brown, on the 83+ diagrams, with the LB-R, meaning Light Blue w/a Red tracer, on the 80 - 82 diagrams. (At least I think that's the way it is, but at the rate I'm going maybe even that is wrong.)
Anyway, my apologies to all, especially 81-F-150-Explorer. I should know better than to question you, my friend.

Don't worry about it, we all screw up!
Cripe, i just screwed up yesterday with the guy who's having problems getting the right radius arms, bill (ND) pointed that out to me (probably unintenionally).
Seems my original thought was right - he can have either forge or stamped, I was reading too fast and got the year of his truck wrong.

I am currently putting a clock out of a 85 into my 1980 that had never had a clock in it I found the plug but the light green wire that should be hot all the time doesnt have power I was wondering if anyone knew what I should do to hook that wire into the fuse box
