I'm re-wiring my 50 chevy 1/2 ton and have a question. My new diagram says to connect the 14 guage wire to the + terminal of the ammeter. Unfortunately, I removed all crumbling wires from the guage cluster before taking note of which one of the 2 ammeter posts had the 14 guage attached to it. The 2 posts are on a slight angle, one higher than the other. Can someone tell me which one is the + terminal. Thanks.
