This Toggle-Turn signal switch provides front and rear turn signals and rear brake lights in vehicles without a column turn signal switch. The switch includes internal magic that coordinates brake and turn lights so everything works as it should.
Once installed, all that's visible is the little toggle switch lever; much cleaner looking than a clamp-on switch. Kit includes terminals and instructions.

When ordered along with our "PCS-Prewired connectors and switches" option, this switch would be pre-wired by RACERS.

Finally, an LED flasher that fits under the WB-9,10,11, 12 &14 BlackBox cover! Every LED flasher we've seen is either too tall or has an incompatible electrical "footprint". This one works perfectly on both counts. The upgrade kit includes two LED flasher units that flash at a constant rate regardless of electrical load. This kit will convert any Enos or Racers BlackBox wiring board to allow use of LED turn signals. (If ordering a new wiring board, order the LED model and this flasher kit is included at discount pricing)
BlackBox Cover - Replacement Main fuse kit WB-9 BlackBox (TM) Wiring Board GM - Points Ignition
Main fuse kit
Our Price: $25.00
Replace that lost or broken cover. Fits all BlackBox models from R-Zero through the latest WB-14. "Get 'em while they're hot!"
Modern cars protect their main body wiring with fusible links, which are fine for them but blown fusible links are sometimes difficult to detect and repair.

For custom vehicles, we recommend installing a 60 amp "Main Fuse" in the battery or starter pigtail that supplies power to the main-vehicle 10-gauge wiring. 10 -gauge wiring is good for about 60 amps and that Optima you have can produce about 1000 amps. If you have a short in the main wiring or ignition key switch, that Optima will turn your main wiring into a toaster (or fire) and it won't be pretty. With a main fuse installed, a problem that would cause a melt-down or fire instead becomes a $2 blown fuse . A main-fuse is a good plan and we install one in every car we wire.

This hard to find fuse holder is our favorite because it's professional, it's easily installed, and it's discrete. In addition to its obvious use in preventing a melt-down, it also serves as a discrete anti-theft device (remove the fuse and she's a no-go) and as a winter disconnect device.

The kit comes with a tab-mount fuse holder, two fuses, 10-gauge wire terminals, and instructions.


After almost 30-years of continuous WB-9,10,11 production, parts to manufacture this model are no longer made. We designed the new and now proven WB-14 with modern components to upgrade the design while retaining the key elements of the WB-9,10,11 series.

The WB-14 uses the exact same base and cover as the old design; only the circuit board has changed. New type fuse holders are longer lasting, there are now 17 fuses instead of 15, and three accessory relays instead of one. Many thanks to the thousands of original WB purchasers. Thanks again for the long ride but moving on to the new, here's a link to the WB-14 Wiring Board (Click Here)
