factory tach wiring
Hi folks....new to the board.Working on getting a '75 sierra 25 4x4 working after sitting in a field for the last 20+ years. Need a wiring diagram or pictures of the factory tach wiring in the engine bay. A pic of the fuse box would help also. Specific question is...does the brown wire run from underdash thru firewall to a "selinoid" on the firewall in the engine bay,to spliter plug and then to the HEI coil????Thanks again.
