Looking for a replacement VDO sending unit with a part number: 340807/1/3 Found one on Ebay that has already sold in January....no others. Not really finding a source on line for this sending unit. If you know of an alternative aftermarket part that would be great.....it has three terminals on top, and looks similar to the one in the picture below (the one pictured only has 2 terminals as far as I can tell). It mounts on the front of the engine just above the fan blade, and next to the turbo. We have checked wiring from front of coach back to engine bay for continuity and it passed.....so did the tachometer, so we are 99.9% sure it is the sending unit. It screws and and engages a "tang", which turns when the engine is on sending a signal to the tachometer.
