I'd like to remove the tach pickup in my 1984 and 85 since just a gunk gunk trap which serves no purpose. The cable routes to an open connector, which presumably dealers could connect a diagnostic instrument to. My cars have a separate pickup on the transmission bell-housing. Problem is that cable is hard-wired into the engine harness so would have to cut wires to remove it.

My 1985 doesn't even have the pin on the crank damper since when I added the support bracket mod for Rollguy's Sanden compressor bracket, the supplied bolt was too long and hit the pickup pin to snap it off. Much better result than cracking the upper oil pan. That Sanden bracket later cracked in several places so went back to an R4 compressor which works fine.
