This installation isn't exactly how-to worthy, but it'll get me one post closer to the 4000 mark.* :lol:
Here's a brief overview of what is involved (http://evo8.initialdproject.com/HowToInstallGMMAP/GM MAP installation overview.mpg)
I really wanted to install a pressure sensor so that I could log boost with the ECU+.* I decided on the GM MAP sensor, which you can buy from gmpartsdirect.com.
Parts needed:
(1) GM 3 bar MAP sensor - P/N 12223861
(1) MAP sensor connector - P/N 15305891
(3) rolls of 14AWG wire from Home Depot.* I like the colors red, black, and yellow (+5V, GND, signal, respectively)
(1) snap connector from Radio Shack
4' of 1/4" shrink tube
6" of 4mm ID silicone hose (you may need more if you're not teeing off another line, or don't have a boost gauge already installed
5/32" tee fitting
solder
soldering iron
electrical tape
zip ties
fish tape
Step 1: Zip tie down the MAP sensor and put on the silicone vacuum hose

Step 2: Cut existing hose, if available

Step 3: Plug in pre-wired connector

Step 4: Insert tee fitting

Step 5: Connect 6" piece to tee fitting

Step 6: Route the wires toward the firewall.* Be sure that you route carefully and don't loop the wires around random things

Step 7: Tape the three wires to the end of the fish tape.* The fish tape is the best thing ever for routing wires in your car!

Sometimes it's tough to get the fish tape through the hole... if this is the only set of wires that you're running through the firewall, you shouldn't have a problem.* I had previously installed my EGT, oil temp, and water temp senders, so I had to use my left hand to guide the fish tape through:

This is where the wires come out -- the hole is on the passenger side behind the glove box:

Step 8: Put in a service loop!* You never know when something will go wrong and you may need more wire later.

Step 9: Solder the ends of the wires -- One is the yellow ECU+ MAP sensor input, and the other is obviously from the MAP sensor that you just ran through the firewall

Step 10: Connect your snap connectors to the two wires.* The convention is that the source of a signal is always female, and the sink is always male.

Step 11: No pics for this step, but it just involves hooking up +5V (red) and ground (black).* You'll have to splice into the ECU harness.* I used pin 81 for the red wire, and pin 92 for the black wire.
I haven't tested my sensor yet, but I plan to in a few minutes... can't wait!* :thumbsup:
