DIY: G35 Coupe TEIN EDFC Installation Guide

Tools needed:

Titanium Unibit
Needle Nose pliers
12mm socket
14mm socket
clip tool or small flathead screw driver

Front Installation:
Loosen the 2 12mm where the windshield wipers rest and take out the clip. These bolts can only be seen with the hood up. There is also a clip located on the tray as well (This is the tray were the water goes down into off the windshield). Use a clip tool or a small flat head to remove the clip.

On the drivers side you will want to drill 2 inches downards from the top of the firewall and two inches towards the fender away from the rubber wiring gromet make sure the hole is small but big enough to snake the connectors through the fire all. Once this hole has been drilled if you look underneath the dash board about 3 inches up from the clutch assembly you should see the small hole that you have drilled (I put a flashlight to the hole from under the hood so I could see it.

Next you want connect the passenger side wiring and lift up the tray and tuck the wriing of the passenger side EDFC underneath (follow the washer hose under the window tray). Once you have the wire snaked into the compartment where you drilled the hole, put it into the hole. Connect the drivers side EDFC wiring and snake that one into the hole as well.

Once the wires have been tucked inside the hole look in underneath the dash were you drilled your hole and pull the two wires down. Connect them to the front EDFC wire and rout your wires accordingly to where you plan to mount the EDFC (I mounted mine in the cubby where the hazzard lights are). Connect the mathcing plug to the EDFC box.

Rear Installation.

Since you are unable to access the rear top struat mounts you must make the holes behind the rear seat a little bit bigger. I would suggest using two people to do this if you do not have the skill to calculate the propper size hole to drill through the rear.

First you want to lower the top rear section of the seat (pull the tab in the trunk to do this) and remove it using the 14mm (there are two bolts located on the the left and right side by the hinges and disconnect the wire that is attached to the handle to pull by lifitng the carpet on the back seat). There are two plastic parts on each side of held by a rubber trim and two clips (one on the top and one on the bottom of each peice. Pull the rubber trim off and remove the clips. Gently wiggle them out to expose 2 small holes on the top of each side. Choose the side that is closest to the pannel and using the unibit expand them (if you are really crafty and want to make a square opening you can use a dremel at 3000RPMS and make a clean cutout to grab the rear EDFC wire). Using the flashlight shine the light into the hole and locate the wire (this is where having a second person outside holding the shock comes in handy...that way he/she can hold the shock in place and guide the wire to you. Afterwards they can screw the 12mm bolt into place. Just be careful not to let the shock drop because you will yank the wiring right off the unit ).

Once the wire is located pull it through the hole/square that you have cut. Repeat this step for the other side depending on which side you did first.
Next you will take out the bottom bench of the rear. Connect both rear wires to the single rear wire of the EDFC and tape them down. Once you have connected them run your wire from the rear accordingly to where you placed your EDFC box and connect to the matching plug on the EDFC box.

Note to self all of the EDFC wires are labled so try to do them one at a time so you do not get confused The front and rear wires tie into 1 hareness each before they are plugged into the EDFC unit.

Wiring the EDFC Box
The TEIN EDFC Box comes with 4 wires:
RED (12 volt accessory)
Yellow (12 Volt Constant)
Black (Ground)
Green (Illumination).

I ran the 12volt directly from the battery, grounded the unit to a peice of metal located undernath the shifter, connected teh illumination to the dimmer switch and the yellow to the power socket on the drivers side.

Hopefully I am able to get some pics up by the end of the week.
This is a tedious task and can take up to 3hours even more if you have no idea what you are doing. You may attempt this at your own risk.
