What is this?
Does anyone know what this is? It’s from an 85 Z28 that originally had an LG4 and was mounted to the firewall by the distributor. Right now, it’s plugged into nothing so I don’t know if it was some sort of filter for the tach or what.

Re: What is this?
Good deal, thanks! So is it just supposed to be inline with the coil wire? I can’t find it on any of the wiring diagrams for my car.

Thanks! I’ll just take it out since that signal will now be coming from the ECU, and I can use that spot to mount the coil driver.
