We might get places quicker if I was more accurate sometimes. Page 4 is the Ford manual. I meant page 7, bottom diagram.
Talk about being stubborn. FFS ! LOL
The Doc told me that the main side effect of the GS! virus is swearing. F$$k he isn't wrong. LOL
Please stop using any diagram other than page 4 in the shop manual, and I'll tell you why.
Even though the colors in both diagrams are the same, and the wiring starts and finishes at the same places, the pin numbers are not the same. E.G. Red = pin 3 in your book and more importantly, in your engine, whereas red = pin 4 on page 7.
Therefore any and all spec testing of volts/ohms should be taken from the shop manual.
Think about how much confusion we had back in the old abyss.
There is no blue wire in your engine, and that's perfectly ok.
Looking at page 4, the 2 squiggly wires starting near points 3 and 1 should go directly to the coil +, and the blue wire removed. Picture that, and understand it. That's more than likely exactly how it is in the engine bay.
Now have a look at page 7, which is the last time we're going to look at it. Right ? Agreed ? Do I have to swear again ? LOL
The red and white wires end up at the coil +, with a resistor in the red circuit. (We already know that the actual wire to your coil + is red.)
I've been meaning to ask you forever, and kept forgetting.
Does the pink wire, top left, in the picture on page 1, have a different, sponge like texture, compared to the green and black wires ?
Whether yes or no, please unplug the connector and measure the voltage, engine off and ignition on, at the pink pin. (I can't remember if you did this already.)
Does your shop manual have a wiring diagram reflecting the ignition wiring ? If yes, please post it up.
No rush for replies to these.
I used to be 7 hours ahead of you, but your recent barrage of posts has spaced my head out, so now I'm light years away, and not sure if it's ahead or behind.
Food for thought. I couldn’t resist (pun intended) grabbing a couple of voltage readings this morning. With key in Run, taken at the disconnected harness plugs into the ICM:
11.95 volts at the red and green wires.
11.95 volts at the pink wire that doesn’t have a matching spade in the ICM socket.
Zero at the orange, purple and white wires.
Proved black ground by getting identical readings with - MM probe on the wire at the plug and probe on the engine block.
It all looks good except the approximate 12 volts at the red and green wires. Can’t speak to the pink. It looks like this is where it would connect to a blue on the module if a blue wire existed.
EDIT: I didn’t see your most recent post before this one. Zero volts with ignition off at the pink and nothing special about the insulation.

11.95 volts at the pink wire that doesn’t have a matching spade in the ICM socket. Yes, this would have plugged into the blue wire, and the blue wire would have been resisted. Good, we can ignore the pink wire.
Zero at the white wires. Perfect. This would only receive 12v during starting.
Proved black ground by getting identical readings with - MM probe on the wire at the plug and probe on the engine block. Good.
It all looks good except the approximate 12 volts at the red and green wires. 12v at the red is spot on. Look at page 4 and note that the resistor wire comes after the connector, not before.
12v at the green wire is worrying. I think ! The green wire goes to the coil -, and I certainly don't expect 12v at the coil -. I could be 100% wrong. Will have to consider that one. Regardless, when you remove the wire covering, we'll be able to see what's what. (I keep saying that. LOL)
Excellent observations. You're definitely understanding it all.
Resistor wires often feel different to normal wires.
Our company arrived yesterday so my time in the shop is limited. I did find a few minutes that allowed time to expose the wiring under the loom from dizzy towards the firewall. Surprise! I found some cut and taped wires and I think one of them is a resistance wire. I haven’t put a multimeter on anything yet. That will likely have to wait until early next week.
Here are some photos of what I found.
Cut and taped wire Two cut wires Cut wires, one a resistance? Appears to possibly be a resistance wire coming from the smaller connector?
H E L P!!!!!!! I have run out of popcorn. I've been following since page 3. Both of you, thanks for such a thorough and descriptive thread. This will certainly help others now and in the future.

You might want to stock back up black and blue 78/9.. This is about to get (more) interesting (crazy)!
I got all excited.......then I seen the get more popcorn comment. Damn I'll be sending more headache pills, and still need to reread alot ive skimmed thru quickly.
When you say your company arrived yesterday, does that mean that you're having back to back boring board meetings ?
Or, when you say company, do you mean family ?
If you mean family, WTF are you doing sneaking off to tinker on your wiring ?
The question is, now that you have seen what you've seen, are you going to be kept awake at night with the thoughts of ''what's under the rest of the tape?'' LOL
I've changed my mind, ''The real Go Seahawks! of FTE'' sounds too girlie to me.
Can we change it to, ''Go Seahawks! versus Go Away Ignition problem'', NFL style ?
If yes, my $$$'s are on GS! winning the game.
Last week you wanted to give OUR project to a local mechanic, mentioning ego, and probably doubting your own abilities. I'm pleased that you didn't.
This is for even thinking about it : . LOL
The following comments are for consideration on +/- Monday, not before, coz between now and +/- Monday you'll be spending quality time with your family.
Looking at the cut wires in picture 1 and 2, picture 1 looks to be a possible candidate.
It looks open ended, and seeing as we're looking for the cause of the 6v to 12v to 6v etc issue, did you happen to notice what is was close to whilst removing the wrapping ?
When you remove the rest of the wrapping, do it in good light, do it slowly, and look for issues.
Once done, clean all of the wires and check for issues again.
What is the black box jammed in between the dizzy and radiator hose ?
Looking at picture 3, at the very bottom, where the wires meet the connector, is that a huge slice across 1 or 2 wires exposing some wire ? Easier to tell when they've been cleaned maybe.
Hopefully the shop manual will tell us if the wire in picture 4 is a resistor wire or not.
The shop manual wiring diagram might also help us to determine why someone cut so many wires in the first place, like the red/brown wires in picture 4.
What's the thick cable for in picture 4 ? (park brake?)
The carb has a ''24'' on it. Nope ! That must be be removed.
It's costing your engine lotsa HP, and must be replaced with ''GS!''.
Now FFS go away, have a Great Thanksgiving with your family, and only return on Monday.
That will allow 77 HOS time to catch up with reading this thread.
It will allow time for the headache pills to reach you.
And it will allow black & blue 78/9 to stock up on more popcorn.
Hang on, is this the same greedy f$$ker who didn't share his popcorn, or at least offer some, last time ???? LOL

Happy Thanksgiving to y'all.
I only skimmed through your post enough to get the gist. Yup, Monday seems to be the day to dig deep in the wiring harness. Unfortunately I didn’t find an engine wiring harness diagram in either the Engine or Electrical manuals which is strange since there is so much detail on other various systems.
I got all excited.......then I seen the get more popcorn comment. Damn I'll be sending more headache pills, and still need to reread alot ive skimmed thru quickly.

Easier to tell when they've been cleaned maybe.
That’s how much time I looked at it. Back to searching.
