Steeler,
I recently installed one of those kits in a friend's Pantera. I used long (12") needle nose pliers. I was able to reach the connector on the back of the tach, so I didn't have to remove the tach.
BTW, that kit is really nice. If the engine dies (like during a cold start with no choke), you don't have to cycle the key....you just push the start button. Pretty cool.
