What is the two wire do dah going to ground on the mounting bolt?
OH...hehe....that is the air temp sensor, that's the plug...this has been setting on a shelf in my garage for some ten years now....computer that ran it flamed out....old analogue thing made by Bendix in Newport News Va. back 35 years ago....GM sent them 3 engines....Olds 350 that appeared in the Sevilles of the late 70's....the Caddy 425 engine this came off of, and then the Caddy 500 ci that I have never seen, but supposedly a very few were made in the '76 Eldo's....
Bendix became Allied Signal, and serviced the computers for GM for years....
then it became Siemens....doubtful any backup for that old op amp analogue computer exists anywhere anymore....
the TPS was a SWITCH not a POT....
air and water temps were identical, HEI ignition with typical mechanical controlls, nothing new there....
due to being a dual plane mani, I had to way tomake fuel rails....so just ran my own dist mani, and welded up the brake lines to the injector tops with clamped on FI hose....ala old Datsuns of the '70's....good enough for them, I figgered good enough for me.....ran that car some 6 years like that....
