Just a thought but I installed one of the reel/corded under hood lights on my 71 4x4 last year. Found one in a parts yard, $10 pull it myself. Really easy install, two wires, hot and ground. Fit really nice on firewall between heater box/blower motor. Course, my truck is a non A/C firewall. Total time for install was about 45 min. to an hour plus two cold beers.
