Well I hooked the illumination wire to the bulb around the climate control *****. My tach seemed to be reading right but.... After driving it aways it started reading erratically and now has stopped reading so i think i have a connection issue and need to connect it better than the tap splice things..

I don't know what type of tach you have. I've owned a couple in my day. The digital racing tachs can get finiky on you, had one on my old talon. Spent a lot of money on it and hated it. Anyway, my 94 F250 has a protach that I installed, simple and to the point.
Anyway, I hooked the illumination wire to the illumated wire off the factory radio harness and the wire on the coil is white or light colored, it's on the left side of the harness when you are facing the truck. There is a red wire on the right side of the harness.
Hope this helps. I took some pictures but don't have a site to post them to, sorry.
