 +Although we can't possibly document all the different combinations of MAP sensors going to all the different ECU inputs, we will at least document the "​typical"​ case of installing our GM-style Omni power 4-bar sensor to the car's baro input. ​ If you have our [[http://​www.ecmtuning.com/​product_info.php?​cPath=26&​products_id=52|SD cable]] then, of course, you can just plug it straight up; no wiring or soldering required. ​ But if you do not, then you'll have the green pigtail shown in [[http://​www.ecmtuning.com/​images/​gmbundle.jpg|this image]].

 +The **red wire** ​ needs to be connected to the ECU's +5v line.  That would be <font 13px/​arial;;#​000000;;#​ffffff>​pin 81 (green w/yellow stripe) on a</​font>​ 2G<font 13px/​arial;;#​000000;;#​ffffff>​ECU harness or</​font>​ pin 23 (green w/red stripe) on a 1G ECU harness or pin 61 (green w/red stripe) on an EVO1-3 ECU harness. ​ This can also be pulled from the MAF connector under the hood.  The wire colors are the same on the MAF connector as on the ECU harness.

 +The **black wire** ​ needs to be connected to the ECU's sensor ground. ​ That would be pin 92 (black) on a 2G ECU harness or pin 24 (green w/black stripe) on a 1G ECU harness or pin 72 (black) on an EVO1-3 ECU harness. This can also be pulled from the MAF connector under the hood. The wire colors are the same on the MAF connector as on the ECU harness.
