Now we move onto the Engine bay side of the install
1. Locate the driver side firewall (just below the driver side hood strut) Take your razor and make a very small .5" cut from inside cutting outward away from the other wires. This is gonna be enough to get all the wiring into the cabin.
2. Next grab the small 6 pin connector and the red wire feeding from the positive terminal. With your small metal rod (or wire puller) grab your electrical tape and tape them to the rod in a gradual increase from the point to the 6 pin connector. To make this easy insure that there are no "steps" in your taping. You want a smooth transition to get it through.
*Highly recommend grabbing some sort of lubricant, in my case I used silicone lubricant and sprayed a fair amount on the tape before attempting to insert. This helped it slide through with ease.
3. Gently guide the wire through the small slit you cut. Be careful to avoid cutting any wires that pass through the firewall. Once inserted a fair amount head into the cabin and pull it through. Now untape and carefully pull the rod back out from the engine bay. And boom you're done running wires inside!
4. Connect the 6-pin connector to the back of the switch housing, either before reassembling the head unit area, or in my case my removing the trim piece to the left tray. To finalize your interior area install take the red wire lead and crimp it to the provided fuse tap. Connect to a fuse of your choice, I chose the 7.5ACC, fuse this way the system only lights up when the key is in the ignition and in ACC or ON. Cut the cover and place back on if you choose or leave off. Tuck and lay your excess wires for a clean install.
5. If you havent already it's time to decide which side you want the unit on. The bracket provided by S-Tech allows for both passenger and driver side. In my case I chose the driver side until I decide the remaining layout of my engine bay.
-Grab your bracket and bolts with the fixed washer and bolt them down about half-way so you can adjust its position in the next step of the install.
6. Grab the unit and the remaining 2 bolts and nuts. And Attach the unit to the bracket. And now its time to make your connections.
7. 60 Amp Breaker-
NOTE: The breaker is marked for the correct connection on that side. Take your positive lead from the unit and bolt attach it to the
AUX side. Then take the lead from the battery and connect it to the BAT side. Once thats done find a place to mount it. I placed it on the side of the engine with a screw through a pre-existing hole.
8. For the ground this connection is up to you. Being a spade terminal I loosened up the bolt for the existing engine ground and slid the terminal in and re-tightened the bolt. And for the last connection run the battery side connection from the breaker to the battery and connect it to the positive! Clean up remaining connections and zip-tie to clean up your install.
9. Connect your battery, take a seat and turn on your ignition and if you did every correctly you'll be greeted by the illumination of the switches!
