You did a nice job with them. View attachment 1715478368
Its odd but the supp doesn't have the circuit coding for the instrument diagram where its most helpful. It seems like it went out the door a little less finished. I verified the 2 speed wiper switch connections against mine last night. View attachment 1715478369

I'm sympathetic with extending wires or adding connections, but it seems like asking for problems. Between the tips and photos here etc, and the 67 Supplement, I was able to reach everything without too much contortion or difficulty. The two points of difficulty were the heater control mounting screws and the unexpected ground wire. The heater screws might have been easier with the panel partially out. IIRC thats what I did 25 years ago when I was working with only the 68 FSM for guidance. This time I wanted to remove all screws and bezels I could with the panel firmly mounted to the dash.
The downside of extensions is more wire too stuff in there without strain on the connectors. And to my thinking, every additional splice and connection is something that could go wrong.

I agree with the extending mostly. All your points are well received. Pay $$ for a new correct harness and you have to decide not to cut/wreck it for future or adapt it. This mod other than my electric choke feed Is the only mod to the new factory harness’s any where in the car. Plug and play and short, heat shrinked for protection. Remove the blue 12+ fuel gauge feed from the barrel and redirect. The yellow wire is an aux ground down to the short factory column to dash mount strap wire for sure cluster ground! Plugged the 5v fuel gauge hole to keep the dirt out as well. I used the Charger Specialty gauges and have been very pleased!
