Autometer boost gauge set-up

[oldsracer]

I bought an autometer C2 boost gauge that comes with a 3 bar (I think) map sensor. Theirs six wires coming out of the plug that goes into the gauge. Three wires go to the map sensor and th other three are power, ground, andsomething else. My question is where do the wires from the old map sensor go. The plug that goes into the map sensor is what Im wodering about. Any help would be much appreciated

the stock MAP sensor doesn't do anything other than make the stock LED boost "gauge" work.. so they can stay plugged into the stock MAP or just unplugged and left laying there.
