Will,
In my original post that you quoted I said
Hook it up to the battery,
that's not right, there is NO hook up for the battery,
DUH
it intercepts the electric signal already powering the throttlebodies, so that's wrong.
You still need to ground it tho.
I got so much crap going to the Eastern Beaver PC8, I just typed before thinking.
Sorry, just didn't want you thinking yours was missing something
when you get it and there's no power connector.
sorry.
BTW, just modified original post to eliminate that bit of confusion.
Didn't even realize it was there till I was reading your quote.
