I have decided to turn my 85 Berlinetta all out drag - and have begun the process of stripping it out completely!

It was a digital dash- speedo & tach doesn't work or can't be seen (I have autometer tach) - and check warning lights section stays lit all the time

However I am trying to preserve

1) operation of the oil, volt and temp dash gauges, and

2) the essential wiring for alternator/distributor (non computer
type) and the head and tail lamps;

How do I go about stripping out all non-essential interior wiring, especially the heavy wiring looms under dash going to computer on passenger side - and the heavy wiring loom in engine bay just in front transmission tunnel

Has anyone done this ?

One idea I figured once I can follow charging wiring and heavy ignition wire, all the rest can be terminated at main fuse block

What do you think??

(( and no, I don't want to buy a new painless wiring block or
rewire car completely))
