I have posted before about power to my electric choke. I thought I had it fixed after squeezing the inline clamp with my pliers. Now after a few days checked and only reading approx 0.00 to 2.45 on my ohmmeter. When I thought I had it working I was getting 11.45 and higher.
I took the clamp off and found my red wire to choke broke off when I touched it near the crimp.
I put the clamp back on and still not a good reading. A fiend pointed out that he found from his experience the clamps aren’t much good after the first use plus I have 2 different size wires and may need a different size or type of clamp,
I have attached some pics and would appreciate suggestions on size of the wiring and how I can best connect the red wire going to my choke and the orange power source wire.

The scotch lock inline taps are good for installing a cheap stereo for a while or emergency trailer light repair. They are not something I have found to be reliable for long term use unless they are exactly the right wire size.
You need a better connection.

Any suggestions on a better connection for red wire leading from choke to connect to orange wire from alternator other than the scotch inline crimp connector?
Pics show where the orange and others bundled run from the alternator.

I’m back.
I have another question. I checked the orange wire with black sthat I was using for power which came from the alternator but not doesn’t give out enough now after 2 years. I put my red ohmmeter prong right into the wire and only get 3.68 reading.

As mentioned in the past it was showing 11.5 and more. Now I wonder what it might have also powered. Any ideas

I tested the yellow wire running right next to the orange wire and it showed 12.5 which is good. Problem is when I turned off the key it was still showing 12.5.

I know I should attach to the Stator connector but to sure about removing the alternator even though it is only 2 bolts.

shown in the pics orange and yellow wires mentioned above. The other 2 are wires on drivers side near firewall. I know 2 ren to the coil and 1 to the distributor. Would it be possible to splice into any of the others.

I cannot help with wire colors on a first Gen. Mustang.
I have used a power tap at the fuse block to add a switched power wire for an electric choke on a period car. It made more sense than worrying about if there was a resistor or resistor wire in the circuit under the hood.

Ok, will check it out. Had thought about looking at doing that.

Put it on the fused side of the fuse clip and you are set.
