Step 1: Upper Battery Mount Removal
Tools needed: Philips Screwdriver
There are two screws accessible initially and once the cover that the blue arrow is pointed to is removed there will be one more screw.
Step 2: Vampire Tap Installation
Tools needed: Needle nose pliers, vampire taps x 2
If present, trim back any protective sleeve covering the main power wires as shown in step 1. The kit comes with four vampire taps, two blue and two yellow. The blue taps will be used if your bike has 16-gauge wires and yellow taps will be used if the power wires are 12-gauge. The gauge will be printed on the side of the wire.
Place the vampire taps around each power wire and clamp them with a pair of needle-nose pliers until you hear them click closed. Ensure that the taps are slightly offset so they lie flat beside each other. Ensure the taps are installed far enough up the wires so the upper battery mount lays flat on the bike frame.
Step 3: Mounting the Armageddon Headlight Assembly
Tools Needed: 5mm Hex Key, Headlight
The headlight assembly mounts on the steer tube – so the stem needs to be removed to install it. Loosen the two bolts on the side of the stem then remove the top cap bolt with the 5mm hex key. If the bike is in a stand, support the front wheel as the fork will drop through the head tube once the stem is removed.
Remove the stem and handlebars then slide the headlight mount over the steer tube on top of one headset spacer. Reinstall the remaining headset spacers along with the stem and handlebars.
Tighten the top cap bolt first, followed by the bolts on the side of the stem. The top cap bolt adjusts the preload on the headset bearings so be sure not to over tighten it. Refer to your bike model’s assembly guide for steps on properly adjusting your headset: https://biktrixhelp.zendesk.com/hc/en-us/categories/360001643632-New-Rider-Resources.
Quill Stem Installation (Stunner, Stunner X)
First, loosen the top bolt of the stem with a 6mm hex key. Be careful not to loosen this too much, as the wedge could come unthreaded from the top bolt.
The handlebars may need to be angled down in order to give the cables enough slack to pull it from the headtube. Do this by loosening the bolt on the underside of the stem with a 6mm hex key.
With a 36mm flat wrench and a large crescent wrench, remove the top nut of the headset.
There may be a spacer underneath the nut, remove this to make room for the Armageddon headlight mount.
Now, you can slide the mount over the steer tube and complete the steps in reverse to install the handlebars again!
Step 4: Connecting the Wires
Tools Needed: Headlight Relay, Needle nose pliers, Electrical Tape, Spade Connectors
Unplug the wires that lead to the stock headlight and run the wire through the frame to come out by the main power wires.
If your bike has spade connectors installed you are ready to move on; however, if you do not have those installed you will need to crimp the supplied spade connectors to the headlight wires with a pair of needle-nose pliers. The wire may need to be folded over so the spade connector has a big enough surface to clamp.
Connect the Biktrix Armageddon Headlight wires, headlight relay, stock headlight wires, and main power wires as shown below. Also, install electrical tape over the connections pointed to by the red arrows.
Red wire with yellow mark from relay → Positive main power wire
Black wire with blue marking Armageddon Headlight → Negative main power wire
Red wire with green marking from relay → Red wire from Armageddon Headlight
Black wire with orange marking from relay → Negative stock headlight wire
Red wire with purple marking from relay → Positive stock headlight wire
*Some bikes may not have red (positive) and black (negative) main power wires. To ensure that the correct wires are used, follow the markings located on the back of the upper battery mount.*
*The stock headlight wire with the white stripe on the side is usually the positive wire; however, if it is not present, you will have to guess which is positive and if the light does not work try swapping the connections. Getting the polarity wrong on the stock headlight wires will not damage the system. Proper polarity should be followed with every other wire.*
Step 5: Final Assembly
Tools Needed: Philips Screwdriver, Electrical Tape
Now, you can carefully tuck the relay and connections behind the upper battery mount then screw it back in place.
Install the battery and test the light! Turn on the light using the same button as the stock light. If all is good, you can slide the supplied black conduit over the exposed wires coming off the Armageddon Headlight and use a few pieces of electrical tape to hold it in place.
