Yes I have a qmb139 4 stroke. DC cdi system and the tachometer is just a cheap Chinese one analog. It has 3 wires 1 pos 1 neg and 1 signal. I do not need instructions for the tachometer. What I am looking for is the best place to get the signal from as it is NOT factory wired for a tach.. 211 Likes, TikTok video from ThatOneMegaMoto (@thatonemegamoto): "Learn how to install a tachometer on your mini bike with this easy tutorial.

MINI-TACHOMETER WIRING The instructions would have you hard wire the tach onto the bike. This didn't make sense to me because every time you needed to pull the cover you'd have it and the attached tach hanging by the wires. So I found a very nice weather-proof three-pin connector at Pep Boys that I spliced into the tach harness.. Wiring configuration is different than most Tachometers.20150213 200330
