I've been really lazy lately... very lazy. Waited 6 months to install a digital speedo in the camaro after the 6 speed swap.
I have the Covan's dash kit which came with the wiring harness. I had been using a mechanical speedo for a while now and was kinda worried about all the wiring hassles.
Wow, what was i waiting for?!? The autometer setup and wiring harness were darn near perfect. I had the pigtail all setup and just hanging there, waiting to be used, except one lead that was easy to modify an existing connector to fit inside the pigtail. Other than that, one wire to sending unit on the transmission, one to a ground. And bingo bango... speedo!!
The calibration was simple too, hold a button, let go, drive for 2 miles (used highway mile markers) push button again. Done.
