What's this plug into?
So the car is a 75, w/L48 auto transmission. Bolted on my intake manifold, driver side rear near #7 is what appears to be either a capacitor or perhaps a signal filter/noise arrestor. It has a single orange wire, with a connector on it. What does this plug into? Thanks in advance for any help

"tach filter"
It's normally in line with the tach wire coming through the firewall.
Look at the distributer and see if there's a plug in the "tach' spot. The tach wire should plug into one end of the filter and the other end of the filter should plug into the "tach" spot on the distributer.
Tach will usually work without it.

Yes...The plug looks like it was mfg.to plug into the distributor. It's about 2-3" from reaching it though. Like I mentioned, bolted directly to the intake manifold where it says 7, one single wire from it to it's plug. Looks like a noise suppressor except for the single wire.

Here's a pic of my unmolested 1976 Corvette. Look carefully underneath the metal brake booster line coming out of the carb, the filter is bolted at this point. Its possible that your tach filter was rebolted in the wrong position.
