Hey guys, I bought this blazer a few months ago. Doing a full restore on it. It did not come with a tach from the factory but the last owner switched out the gauges to one that had a tach. He did not wire up the tach but had the tach wiring harness.
Here's a picture of what I have. Is this all I need to hook up the original tach? I would think the pink wire would hook up to the distributor. Where does the brown wire go? It has the original distributor in it I think.
