Voltage Stabilizer Mounting Location 1800 1973

The dash in my 1800ES has been torn apart too long! I can't recall where the oil pressure / oil temp / fuel gauge voltage stabilizer actually mounted. The wire lengths suggest it's in the vicinity above behind the tach or speedo. The size of the hole in the mounting tab suggest it's a rather small screw that secures it. The wiring diagram suggests it needs a solid mount to ground. Does it share a speedo or tach mounting post, held in place by one of the thumb nuts?

Wait, I remember one of the mounting posts had two thumb nuts for some reason - did I just answer my own question??

    Chris;

    You did answer your own question! It is typically mounted under the Tach or Speedo securing thumbscrew (I don't recall which one, but wire length and location in the harness should make that fairly obvious).

    Yes, it does need a good electrical connection to chassis which that provides (I guess), but a specific wire to chassis could never hurt.

    Cheers

      It actually mounts on the oil temperature gauge mounting stud.

      And it is a major pain in the neck to install.

      I like to remove the tachometer to give me some more room.

        Thanks, Ron/Eric.

        About the ground - my car has a black ground wire that daisy chains from instrument-to-instrument, attaching at one thumb screw on each instrument. It grounds to chassis at the far LH side of the dash. It doesn't show on the schematic but I'm sure it's OE.

        I knew I wasn't going to enjoy this part of the project. Just hoping I've selected the best working instruments out of the bunch so I only have to do this once. Dream on?
