Fre530d Posted December 27, 2006 Report Share Posted December 27, 2006 (edited) Hello Guys So i am installing a Trailtech vapor speedometer. It is possible to supply it with power so the backlight stays on so I used the White/black cable from the tors (I cut the connector that goes at the black tors box that i don't use anymore) as positive lead and the black cable (ground) as a negative. I saw this in clymers manual. It's also possible to measure the rpm so I twisted the red cable around the sparkplug cable and connected the black cable to the same ground as I did with the power supply cable. But as soon as I start the engine the display starts reseting. I just can't get it to work properly. Anyone got some suggestions, experience? Maybe a better source to tap power supply off?
