Yes I'm back with another DIY. Mods please leave this here for a little, I know where its supposed to go, just want people to know its available.

Ok I got a 9 wire kit for the G37S 6MT, red color is very nice and wire look good quality. Make sure you set yourself 3 hours of time for this, I could have done it quicker but it was hot as hell over 100 degrees outside and humidity high and I dropped a couple bolts and nuts and that took some time. Also installed 2 wires in the wrong spot so had to fix that.

Ok 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 and used the long bolt they gave you and screw into the hole with a yellow circle and it will look like this.



Next take wire 2 and hook it to the closest bolt holding the throttle body on the left and attach. 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 and 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, and 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 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 make sure yours looks like mine.



Now for the Pain in the A$$ part, The ECU wire.

While your still under the hood, pop the 5 plastic clips holding the battery compartment with flathead screwdriver and remove the cover. Then remove the 2 clips holding the plastic windshield trim. and 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 under the glove box 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 make some screws easier. Check Picture.



Next remove side door trim piece.



Pull out glove box area and dont pull out the wires by pulling too hard

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 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

Its supposed to help flow of all electronics, which Infiniti's have lots of. Its also supposed to be good for a few HP and little better gas mileage. I just put it on yesterday but I noticed the A/C get cooler faster and the lights looked a little brighter and car seemed to have a little better acceleration. I'll let you know if I notice anything else. Also it looks cool under the hood lol
