Question Subaru Loyale - MPGuino Install

Howdy! I've been reading this forum for the last week, getting stoked on all kinds of mods. I just bought an MPGuino, it showed up in 2 days, I installed it tonight, and clearly I didn't pick the correct leads to tap into.

The unit displays just fine, but it isn't picking up VSS. I think I tapped into an unused VSS connector, but I just found on the Rostra site that I should tap into the YR coming from the speedo. Tomorrow...

Perhaps a bigger problem is that, in the custom screen, it displays 6.5 GH at idle, and the number decreases as I add engine load. Neither of these terminals showed 12V with the ignition on and the engine stopped, as in the instructions, so I just tapped into the RW on this schematic. Will switching over to the other lead to the injector fix things, or is this a peak-and-hold problem?

My car is a '94 Loyale Wagon, 5spd, non-turbo, SPFI.

Many Thanks,

(Disclaimer - I'm a mechanical engineer, not a sparky. The vacuum gage went in tonight too, and works just fine )
