For working under the dash on short wires, a good friend sent me gift : KNIPEX End-Type Wire Stripper.
This would have saved a lot of creative cursing under my 1954 dash last week. My Suburban has several 6v accessories: electric-wipers, original steering-column-mounted turns-signals, original-style/size radio/seaker, and original deluxe Air-Flow Heater.
I had wired the ignition switch incorrectly and my good friend did not approve - I said "you volunteered to crawl under the dash to correct/re-route that rat's ness of wiring".
The swear words were creative and they were effusively used; and, the fingers and knuckles were severely abused and sore.
The
KNIPEX 11-160 End-Type Wire Stripper would have helped a lot.
