Vehicles covered by this write-up: 2005-2006 Cobalt LS & Supercharged
Installation Duration: 1 hour
Skills needed(1 being least and 10 being expert): 2
Parts you need to purchase:
Some sort of gauge pod(your preference)
Air/Fuel Gauge(Summit Racing brand Part # SUM-G2986)
Wire
Crimps
Tools:
Clothes hanger
Wire cutters and strippers
Crimpers
10mm socket & wrench
Directions:
1) Disconnect battery(located in trunk)
2) Install gauge pod onto A-pillar or whereever following their instructions. I used a a-pillar gauge pod and had to attach it with four screws and drill a hole for the wires as I'm going more for function right now.
3) Remove rubber plug on firewall located as shown. Slide clothes
hanger through hole and find in the engine bay. Attach two wires to it
and pull back through. This is your power wire and A/F signal wire.
Mark them to keep them seperated.
4) Hooking up the power wire - using a crimp put the red A/F
wire(power) and crimp it into one side. The power wire you ran through
the firewall will be connected to the other side using the same method.
5) Now adding power - Take off the fuse box cover and find the IP Ign
fuse. A mini green 20A fuse. Strip off some of the wire and put this on
ONE side of the fuse and re-insert fuse. Congrats-You have power now.
6) Hooking up the signal wire(grey wire) - Perform the same method as
connecting the wires as you did the power. Locating the signal wire is
fairly easy. In the bundle of wires next to the ECU locate the Purple
wire with a white strip. Cut this wire and strip the ends. Connect the
signal wire you ran through the firewall on one wire and connect the
two using a crimp.
Location of bundle:
7) Hooking up your ground - Anywhere will be great, but I used the
metal bracket that supports my clutch pedal. Just removed one bolt put
the black wire there and bolted it back down.
8: Reconnect battery and check wires and make sure everythings snug.
9) Crank her up and watch the gauge. Give it a second to get the signal
and tap the gas a couple times to see if the gauge changes. After a few
minutes of idle it may dance which is normal.
10) If everything is working properly you are finished!
Disclaimer: Do not put gauge where it will affect your night time
driving. I am under no reason responsible for where you install it.
Please drive safely & responsible.
