Thanks dcb,
Yes, I think I got a pretty good fix on the usec/gallon. I am using 0114596879.1. That may not be dead on, as I had driven about a mile before I was able to recalibrate, but it is close.
I had assumed it was 12v, but learned tonight from a site that the vss signal gets a 5v feed. I tried the vss input wire tonight, but it only seems to get a signal up to about 5 mph, then nothing. I was thinking about finding the feed off the tranny before I read that thread. Now I'm at a loss. Any ideas? Thanks, Dave
edit--I forgot to ask, how could I measure this while driving?
