but electrical is not my strong point, no where near it honestly but calling around to a few shops and getting estimates of 1,700-2,400 is just to much for me.
You have a nice mess under your hood; I especially like the doorbell or phone wire. This presents a great opportunity to learn how under hood electrical devices work, and how to properly wire them to form a reliable well engineered harness. Once these lessons are learned, automotive electrical issues will never again intimidate you.
I was faced with a lot of crappie wiring methods in my ’67 Dart. Under hood I replaced bulkhead connector with new, and replaced each wire one at a time following factory diagram for wire color, and adapting to upgrades as needed such as conductor size, electric choke, electronic ignition, charging bypass, relay controlled headlights, and others.
Make several photo copies of a big block V8 72-74 under hood wiring diagram to use as a work sheet while project is under way, clip it to a clip board, and invest in some colored pencils to help keep track of progress. Just repair or upgrade one circuit at a time, and once completed mark it off the diagram.
As work progresses, you will learn how each device works, how to test it, its conductor’s color and gage, and where its terminals are located. Once all work is completed, tested, and all circuits work properly, bundle new harness in some sort of harness loom to make a neat clean looking installation.
