hey everyone, i am having a problem with my cyberdyne speedo, i tapped the dark drenn wire with a stripe in my sunfire behind the cluster and its not reading speed, they gave me a sender to use but said that i might not have to use it, i talked to gary on the org a month or two ago and he said that all he did was tap that wire, and push the calibrating button at 45mph, did i tap the wrong wire??? or do i have to use that sender?? its a 95 2.2 auto sunfire,
thnaks for the help
