Been there - done that, it is not difficult at all. Trick is to find a donor vehicle that has the RPM sensor mounted on front of engine to pick up the signal from a pin in your crank-balancer. I'm not sure what the break-point is but later years have the sensor at the flywheel end. I bought the whole set-up from a fellow parting out an '81 300SD: Sensor with mount and wire to tach. amplifier, tach amplfier and mount with wires (cut) to fuse box and tachometer, and tach w/ integrated clock.
Only took me a few hours to install the whole works, and I was going slow. Pretty much plug-and-play. All the holes for the mounts were pre-existing, and the pin was in my crank-balancer (it is needed for the diagnostic tests that call for measuring RPM). -- Very respectfully, /s/ Max Dillon '87 300TD, 310k miles Charleston SC Digest lurker (on and off) since 2001 _______________________________________ http://www.okiebenz.com For new parts see official list sponsor: http://www.buymbparts.com/ For used parts email [EMAIL PROTECTED] To Unsubscribe or change delivery options go to: http://okiebenz.com/mailman/listinfo/mercedes_okiebenz.com
