Hello, this is my first post here. I have a 74 f100 I put a 7.3 psd in. I used the factory instrument cluster out of the 84 and adapted it to the 97 wiring harness as much as I could. By doing that I do not have a tachometer anymore. I would like to put an aftermarket one in. Can anyone tell me if I can just use the wire that comes from the pcm to power the aftermarket tach? I would prefer to not use the auto meter alternator adapter if possible. I’m open to any other options as well.
