A representative flasher top looks like the above photo. 3 pin flashers have an additional terminal labeled 'P' for the pilot light indicator. That may do the trick. 2 pin, electric relays, not the mechanical type like fitted to old cars that tick when they flash. An ISO micro relay has the control circuit connected to pin 86 and pin 85, and the load circuit connected to pin 30 and pin 87 or 87a. I quit riding anything two wheeled a good many years ago. I decided to write a review to help others clarify that this does replace the original three (3) pin/prong relay. Here are two simple animations illustrating how relays use one circuit to switch on a second circuit. Where I'm getting lost is the concept that the 2 prong relay will plug into the 3 prong socket and bridge the brown and brown/white wire. A more complicated circuit, in which a 555 timer IC controls a flood lamp via a relay is another option. My motorcycle (like many others) has a 2-pin flasher relay to make the turn signals work. On many relays there are at least two switches inside so that you can switch two devices at once. What turn signal module does my TJ have? You'll either need a micropower circuit that that will run off as little as 2V and a boost circuit for the FET gate drive, or a reasonably low value resistor across the LED bulb load. it could get you a traffic ticket. A relay controls something, and without that relay, that something will not work. As a result, the load which is connected with the Relay also triggered. But the current flow through the heater IS enough to heat up the bi-metallic strip. The entire cycle is then repeated, but with LOAD 2 energized first. 1951 GMC 1 Ton Flatbed -- It is finally on the road and what a great time I have driving it! This has me stuck.
