What I did with the one I wired in the wagon. Is right next to the fuse box there is a large white wire going into the fuse box. Disconect that, run a wire from each side of the two terminals to the two white wires in the tacho, it will now work. next is to wire the lighting on it, I just found the extra plugs under the dash (which was easy for me as I had to remove the clock) the two other wired plug straight into that. All Done. Hope that is easier?? Rick White.
Saves having wires coming from the coil.
