LED Turns WITH stock self cancelling (Working)

[danny01975]

So I recently switched my incandescent bulbs to LEDs. Much brighter, and now I don't have to search high and low for 23/8 Bay 15d bulbs. But my self cancelling didn't work anymore. Honestly, I always thought the stock canceling was way too short at 9 seconds. So I wired up this solid state relay / timer. It has all sorts of different timer modes. I programmed it to turn on as soon as the switch is activated, then it waits for the auto cancel signal from the TSCU, then waits and additional 20 seconds before turning off the lights. If you activate the switch at any point, the process starts all over. So the TSCU is what's controlling the relay, which is controlling the flasher. Exactly how the stock flahser worked. Except this one is a little smarter.

Now I have LED lights + the stock functionality of the TSCU with the whole speed sensing timer thing, AND more time. And I can adjust it to whatever timer works best for me.

We'll see how well it works over time. Just thought I'd share in case others there want LED but still want self cancelling. There are other ways to do this as well, but this wasn't that hard to do and wasn't that expensive.

This is how it's wired.

Update: 5/25 This has been working flawlessly since I posted this back in February. Time to clean up the "test wiring" under the side cover and make it permanent.

Update 7/25
I was able to make 3D printed case to house the flasher and TSCU. Finding a male flasher plug with wires was impossible, so I bought a cheap flasher from the auto parts store a took it apart and stole the metal blades out of it. Now I have the whole thing in one box slightly bigger than the original flasher. It just plugs into the stock harness. If I ever need to go back to factory, I can just unplug it and plug in the old one. This looks way neater too. I can't believe how long it worked in that rats nest of a "temp" setup.
