Ok, I got a red, 9 wire kit for the G37S 6MT. Make sure you give yourself about 3 hours of time to complete this.
First, remove the engine cover
Next, remove bolts near the dipstick (circled in red and yellow)
Now take wires 1, 2, 3, 4, 5 and the factory wires. Use the long bolt they gave you, and screw into the hole with a yellow circle. It will look like this.
Next, take wire 2, and attach it to the closest bolt holding the throttle body on the left. Take wire 3 and do the same for the right throttle body. The bolts are circled in red in the picture above. After you connect them they will look like this.
Next, take wire 4 and connect to the factory ground point to the right of the intake filter. If you have Fujita intakes, you will need to unscrew the rubber stabilizer to remove the farthest factory ground. Take both factory grounds,wire 4, and connect in the left hole.
Next, take wire 5, and remove the nut holding the lower plenum, at the center rear of the engine. You will need a deep socket with a small extension. Area is circled in red.
Next, take the supplied 25mm bolt, and attach the other end of wire 1, one end of 6, 7, and E (Yes I said E) at the factory ground point, with the factory ground wire. This is circled in red at the bottom of the picture.
Your engine bay should look like this at this time.
Next, take the the end of 7 and 8, and attach them to the factory ground point, circled in red, along with the factory ground wire. Use the 16mm nut supplied.
Next, you will see 2 holes where wires go into your battery compartment. Pass the B end of the #8 cable through the left one (just put it on top of the other wires). Next, pass the E wire through the right one by running it on top of the other wires. Check and make sure yours looks like mine.
Now for the hard part. The ECU wire.
While your still under the hood, pop the 5 plastic clips holding the battery compartment. Now, with flathead screwdriver, remove the cover. Then, remove the 2 clips holding the plastic windshield trim. Remove the left side piece by jiggling it, and pulling up gently. Now, cut or drill a hole in the rubber boot that runs the wires to the ECU. Look in the picture and make the hole in the same spot.
Now, go into the passenger side of the car, and under the glove box, remove the plastic piece, by pulling down on the front.Now, remove the 7 screws holding the glove box area in place. You might want to remove the box in order to remove some screws easier. Check Picture.
Next remove side door trim piece.
Pull out glove box area, and don’t pull on the wires too hard. They might come out.
Now, finish feeding the wire down the hole you make, and connect to the bolt in the picture.
Now put your glove box area back together, and head back to the engine bay.
Last step is to connect wire 8 to the bolt that’s holding the negative battery connector. Then reinstall batter cover and windshield trim. Next replace your engine cover, and your done! It should look like this
