Whether you're a professional engine shop, harness builder, or just a shade-tree hobbyist upgrading the ignition on your classic car, Widget Man has a product to make your life easier.

RATIO CHANGERS: Modify the number of pulses per turn for tachos, speedos, trans and powertrain controls, and pulse-driven accessories like shift lights and dual-speed fuel pumps. Modify frequency and/or polarity of PWM pulse trains.

SIGNAL CHANGERS: Boost, drop or modify voltages and signal formats for incompatible devices. Boost voltage for back-EMF tachos, drop voltage for 5V ECU's, turn square waves into sine, sine into square.

RPM SWITCHES: WM's patented “learning” algorithm lets their RPM window switch work with any RPM signal and be set up in the garage with a few pushed buttons. No displays, no charts, no fuss!

E-FAN CONTROLS: Make virtually any brushless PWM or DC brushed fan work with any engine, any temperature sensor, or any ECU.

GAUGE MATCHERS: Make virtually any analog gauge work with any sender or sensor! Yes, we mean ANY!

The small form-factor and durable construction of Widget Man designs make them ideal for embedding into swap harnesses, or burying invisibly under a fuse block or dashboard. All WM devices are rated 225F or higher and most have internal fusing and polarity protection. Many are IP65 or IP67 weatherproof, and ones that aren't can be easily weatherproofed with a few dabs of RTV. Professional inquiries and volume sales are welcome, contact us!
