Main Relay Kill Switch
This modification will disable all components connected to the main relay.
Time: 20 min. (or more depending on switch location)
I Have included close up pictures for wire, color, and location reference. As well as a list of wire terminals and destinations
Materials and Tools:
-Desired length of wires for switch location (20 gauge or thicker)
(having dual insulated wire like shown makes routing and looming super easy)
-Wire Loom (Get enough to sufficiently if not completely hide all new wiring)
(should be big enough to fit around all wires for harness and new switch wires)
(this is the same switch I have/it's a 5a 125vac switch)
-Other Materials For Hiding Switch Better
1.Find a location for your switch. (It doesnít have to be hard to access to be well hidden)
2.Make sure the switch fits and wonít have or create any clearance issues.
3.Determine the length of wire needed to extend from your switch to the main relay while staying hidden.
3 1/2. Remove anything necessary to run wires.
4.Run your kill switch wires along your desired path. (leave a couple inches slack on either end)
5.Find the Ground Wire for the main relay harness and cut it at the desired point.
6.Strip both ends of the cut Ground Wire.
7.Strip the ends of your kill switch wires that are at the relay end
8.Solder Kill Switch Wires to the 2 ends of the cut Ground Wire.
9.Tape the new connections to keep the wires insulated.
10.Mount your switch in the desired location.
11.Strip both wire ends at the switch.
12.Solder Kill Switch Wires to the switch.
13.If possible insolate the connections
14.Test the switch. (it would suck to have to tear a bunch of loom and tape off to fix something)
15.Go back and loom all exposed wires. Make your work as hidden as humanly possible.
15 1/2.It was brought to my attention that a thief could easily bypass this by sticking a wire into the pin and
grounding it straight to the body. If you are worried about this you could always relocate the relay. (I didn't
mention this earlier because I didn't feel it was neccessary after all looming and taping was completed)
16.Put Everything back together.
17.Sit back and enjoy your new layer of security
Location of main relay: Right above hood release lever and next to fuse box.

Thereís some info that Iím missing for later models. As well as a questionable color for terminal 5. If anyone can confirm and give me the missing info I would greatly appreciate it. Just PM or reply with info.
Please feel free to leave any comments questions or suggestions. Let me know if there is any info I left out or that you need.
