Can anyone walk me through a start up for the aem? i just bought it from champanz here on the forum, and i need to know wat all i need to do so i can get it to my tuner, i looked on aempower.com and didnt seem to find any threads talking about where to and how to install the 3.5 map bar sensor and the air temp sensor, if some one could help me i would really appreciate that

Here is a sketch I made with some wiring notes on the sensors.

Unless it came out of a car with an identical setup you're going to need to do a fair amount of tweaking to get it in the ballpark. Even if it does already have a good map you should start over from scratch, a new cal will get rid of any problems that may have developed.

Yeah, you'll need a cal file set up for your injectors and sensors.

seems that you can just put the 2 wires for the IAT sensor into the MAF plug, just like any of the other temp sensor's like the VPC resistor or MAP ECU temp sensor

as for the map sensor, I am using the AEM 5 bar map sensor. do all 3 need to go to the ecu, or just the green (sensor output wire)? can i just wire the positive to a constant 12v and the ground to a constant ground? or do they all need to be run through the firewall and go to the ecu pins? also, do you know by any chance if the pins are the same for OBDI and OBDII? i think there is only 1 version of the AEM but just makin sure
