Review on Bosch Sport II 2-5/8" Tachometer (Black Dial & Bezel) by Actron SP0F000025 by Curtis Thilges

21 year old, 4 cylinder, 5 speed manual pickup and no touch. The price for this small Bosch tachometer was right. I wouldn't call the installation "easy" - I spent about an hour trying to figure out where to install it without ruining my truck's 20 year old plastic. Then it takes some time to lay the wire so that it does not interfere. Black wire = battery negative ground. Red wire = 12 VDC power. White wire = lighting (could be brighter). Green wire = signal, in my case, from the truck's ECM under the hood. I would say it took me at least 3 hours to get everything looking good. That was two weeks ago and it works great.
