Thanks for that, Dan. A couple other questions if you please...
Did you ground the MS ECU to the chassis or the engine block? I was doing some reading and it seemed like the preferred method is to the engine block due to possible voltage drops, but it's also possible that I'm reading that wrong. So, just curious as to how you set that up.
Also, did you connect the power grounds (pins 15-19) to the same ground point?
Finally, not sure if you connected a the brake booster vacuum line to your vacuum manifold, but if you did, which direction does the vacuum flow? I need to make sure I install the check valve in the appropriate way

I was thinking it would flow TO the manifold, but I'm basically just guessing
inching ever so slowly forward....
