doc thanks for your reply. i'm kinda hoping the terminal numbers aren't in the pass dept. the # 50 is a jumper wire that you attach a remote starter to bump the motor. this also the same cluster that you use for tuning the electrics. i think my biggest problem is my 116/117 engine book was printed in 84 and it appears that they do not address the 72 directly because nothing in the book resembles the engine compartment.
marinmbfan, thanks for your offer. i too have all the cd's and the hard bound engine and chassis books. i'm thinking however the cd's will be a beater source because it addresses the year 72. i'll have to go to the cd tonite to see if i can run this down.
there is a item (switch mechanism) that none of the books i have even address. the cd should shed some lite
