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.

Bill, if you do decide to remove the pick-up, I'd like to have it. I've got a tach install project on a '78 300CD I need to do. I've got the tach binnacle and the amp, just need the pick-up bracket.

After hovering on a Sanden kit for years I went with the Klima Design one solely due to the series of revisions/mods of the kit you used. I'm sure every big undertaking involves revisions but normally it happens privately one-on-one. It's got to be tougher when the problems have spectators. If it's ever time to go back to a Sanden, Klima will sell just their bracket set. The component that really dropped vent temps was their parallel flow condenser. It also reduces the amount of refrigerant required. A W123 OE charge weight for R12 is right near 42oz(3 x 14oz cans). After the PF condenser 28oz was the magic number.
