I remember the wiring on my 1st project - an 80 Turbo T/A. The more I examined the wiring, the more splices and electrical tape I found.
My present '67 WAS a rats nest under the dash. Aftermarket gauges mounted under the dash and an alarm system did not help. Between the age of the original wires, the greasy mess that they were and all the taps and splices over the cars lifetime - I decided to replace ALL the wiring.
Nothing like spending years and big bucks so you can see your car burn to the ground.
