i am using a obd 0 engine harness on my LS engine and need to buy a 3 bar map sensor. i heard a rumor that the new model numbered GM 3 bar map sensor (12223861) is a little more difficult to wire up than the old one was. is there any truth to this and if so, what? also, would i have to buy the pig tail connectors for this set up? thanks

btw...anyone know whats involved in wiring one of these puppies up?
