Tachometer and sensor for 12V W460 and W461 Gwagens that have a ring-gear sensor port on the oil pan. This includes OM602, 603, 605, 606, M103, 104 and anything else with a same tooth-count ring gear and sensor port. *Please note, this is a used gauge with new bezel & cleaned face, but there are some small marks on the glass lens, as (barely) seen in the photo.
Tach requires +12V supply from ignition, ground wire (brown), and a wire for the lamp. The included sensor has a plug that can be removed and replaced by single female blade connectors (I can supply these too) that plug directly into the back of the gauge. No wiring harness required! Most G's have the necessary connections already available. VERY simple to add to a no-tach G.
