What are these parts on my firewall?
71 GMC Sierra Grande with a mid 80's SBC 350.
Can you tell me what these electrical parts are on my firewall?
I've unplugged them and don't see anything else not working but my tach has never worked. At least one of these parts (relay/voltage regulator/ac generator/unknown) looks pretty old.
Thanks guys.
