Thunder Ignition Switch Relocation Kit
Many people who’ve ridden Harleys with a tank-top ignition switch have had good things to say about its convenience and the bike’s ability to be operated without the key in place. The folks at Thunder Mfg. must have had similar experiences since they’ve adapted a Harley-style switch to their slickly machined billet plate, turning the dash plate on Classics and Nomads into a beautiful and functional piece. The stock warning lights are retained, so the Thunder Ignition Switch Relocation Kit doesn’t come with any compromise attached.
- Wire cutters
- Solder iron (150W or more)
- Black electrical tape
- Shrinkwrap (optional)
- 8, 10 and 12mm sockets
- 4mm allen wrench
- No.2 phillips screwdriver
Installation time: 1.5 hours
The first portion of the installation proceeds in the usual manner-the seat, tank and ignition switch must be removed. The Thunder kit requires the connector for the ignition kit to be moved, but it simply gets pulled through the frame to where the connectors for the instrument cluster reside. However, the wires from the ignition switch itself need to be cut off and soldered to the Thunder switch. The operation is relatively easy, but it does require a soldering iron or gun with some horsepower, or the process becomes an exercise in patience.
Halfway through the installation, when our tired, old iron gave up the ghost, we popped for a Craftsman dual-temperature soldering gun and finished the job in a quarter of the time we had labored over the first half. Since weak connections could cause the ignition to fail at speed, we consider the extra time and money spent to be well worth it. The warning lights also require an OE connector to be cut and soldered onto the Thunder kit’s lights. For security and a professional look, we covered the joints with heat-shrink tubing. Finally, just before mounting the relocator kit to the bike, we took the extra precaution of wrapping the connections for the switch with electrical tape to ensure that we didn’t inadvertently short any circuits when mounting the kit to the instrument cluster.
The switch assembly looks great and works like a charm, offering on, off and park settings. Newbies to this type of switch be warned: Don’t ride off with the key in the ignition. Unlock the switch and pocket the key, or it may become another piece of sparkly garbage on the side of the road. And don’t forget to retain the OE key—fuel still needs to get into the tank!
Pro-One Billet Choke and Key Switch Relocator
Special notes: Installation on the Nomad requires the Vulcan Classic’s choke bracket . The choke cable must also be rerouted.
Often the left side of a cruiser looks like it was ignored by the stylists. Pro-One’s Billet Choke and Key Switch Relocator moves the ignition switch to a more amenable location for folks that don’t have simian arms. And it dresses up the look of the engine bay!
The heart of the kit is a chromed billet plate that nestles in between the rear cylinder and the frame, just in front of the left side cover. Both the choke knob (dressed in a spiffy billet cover) and the ignition switch mount to the plate, which cleverly mounts to the OE choke-cable bracket. (This is why Nomad owners will need to buy a Classic choke bracket.) Installation is straightforward but it takes a few hours—only because of the care and dexterity required when working with the main wiring harness.

After removing the seat, tank and ignition switch (You do have a factory service manual don’t you?), two tricky tasks present themselves. First, the plug connecting the ignition switch to the main wire loom must be relocated rearward. The space between the frame rails is packed surprisingly tight. To avoid damaging wires, resist the urge to use a screwdriver or some other metal tool to pry the loom away from the frame. The trickiest part of this operation is the unwrapping of the wire loom. Be careful with the wire cutters when making the incision on the tape wrap! Once the tape is cleared from the area, the ignition switch wires—with one exception—can be separated from the loom, gaining the length needed to move the connector far enough rearward to facilitate the new switch location. The kit includes a premeasured extension to crimp to the one wire that must be cut. For an extra measure of security, the connections could be soldered.
The second tricky part of the installation only affects Nomad owners who want to use this kit. Since the Nomad’s choke knob is mounted under the ignition switch, the choke cable must be rerouted to the rear cylinder. The left-side air cleaner, filter, backing plate and snorkel going to the top portion of the airbox must be temporarily removed. (Actually, only six screws and one bolt get unfastened, so it’s not a lot of work.) After the cable is freed, run it down the outside of the left frame rail with the newly lengthened ignition-wire harness.
Mounting the Classic’s choke bracket requires only patience and an 8mm wrench. The two bolts on the fresh-air-induction system mounted on the back of the rear cylinder (Remember that repair manual?) must be removed to attach the bracket. Unfortunately, thanks to some frame interference, the top bolt doesn’t slip out unless the entire block is shifted about a half-inch to the left. Be careful not to damage the gasket or annoying, frequent backfiring will occur when you roll off the throttle.
The final stage of the process is the installation of the switch and choke cable to the relocator. We had a momentary struggle when attaching the relocator to the choke bracket, but once we’d constructed an 11-inch extension driver from the various sized extenders in our toolbox, the relocator mounted up perfectly. Operating the ignition and choke is the same as before the modification—only much more pleasurable. Although the stock seat covers it, bikes with aftermarket seats may leave the connecting plug for the ignition switch out in the open. Particular folks may want to lengthen the harness a few more inches by splicing longer wires to the loom.
