Hmmm, I wonder if that explains the strange behavior of the tach in my 
Eagle. Ever since I installed the 4.0 and Renix, it's behaved strangely, 
especially at low speeds. A few weeks ago, the tach died altogether, 
freezing at 3000rpm. The fuel gauge was acting strangely as well, 
jumping around like Earls friend Catalina, so I swapped in a spare 
cluster I got a while back at the u pick em. The gas needle stabilized, 
but the tach is dead in that one too. Usually hangs straight down, 
occasionally wiggling in response to rpm changes. Seems I gotta pore 
over the diagrams and see if I can remember how I wired it...
