One wire is kind of hidden-I highlighted it in yellow. Refer back to the original picture to see it without the highlight over it.

Okay, now I see it ... yes, it's camouflaged, dusty/dirty black against black.

Griff,
Any idea which size of heat shrink for which diameter of wire? And what size are those ICM wires?

Nope, my supply box isn't handy ... someone borrowed it and I'm getting ready to put out a contract on his A$$!
Measure the diameter of your wires and get the next bigger size or two steps larger. (Calipers if you have a set or a tape measure and mark one eyeballs.)

Here is how to find wire guage.
You do need a micrometer. I do have one but I would need to cut a wire to measure it.

That's why I keep mine on the spool and only use odds & ends for jumpers and testing.
Figuring out what size wire is in a circuit is trickier, as you indicated. I try to figure out what size it is and go one size larger. (Slightly larger never hurt ... much larger doesn't hurt either but wastes money.)
Having said that, the size of heat shrink tubing needs to be at least as large as the outside diameter of the wire insulation. Two or three sizes larger, depending upon the size of the terminal crimp barrel or your splice. The neater your splice, the smaller the tubing can be, as long as the tubing fits over the splice.
The tubing shrink a lot so somewhat larger tubing will work.
BTW - I normally used uninsulated wire crimp terminals. I also solder the wire inside the terminal barrel after I crimp it. Final step is slide the tubing over the barrel and heat shrink it.
If I don't have uninsulated terminals, I strip the plastic 'insulation' off readily available terminals.
Also, heat shrink tubing, if it's an inch or so longer, serves as stress relief. (A double layer of tubing, if I think the wire will experience a lot of stress at the terminal.)

When i order a new ICM for my 1979 Dodge with Carter Thermoquad 9207s, should i order an ICM for an engine WITH or WITHOUT electronic throttle control? I don't know how to locate this part. There are information, that 1978 was the first year when Dodge engines came with electronic throttle control.

So, time has gone by, still starting right up with a pump of the pedal. Awesome. Ignition module to the rescue.
Bit of other news... for the first time since I've owned it... I think the exhaust is finally fixed and without issue. Put a new muffler and tailpipe on last fall, found a crack and a leak up by the manifold and got that and the header gasket fixed. just kinda purrs now. My oldest said it doesn't sound as powerful now. lol. Should be a nice trip this weekend.
