3 bar map sensor
 

I just purchased the 3 bar map sensor from GM and thought I'd update the site with the new part number. They still use the old one as a cross reference but here it is anyway.
NEW NUMBER = 12223861

Where'd you get it from. GM parts direct has them for $50.55. Other than ebay, is there anywhere that has a better deal?

Tell us how to wire it up with the GM plug ,please .

the wiring is on the forum. just do a search under nocab72's name.
