Cleaner than just wires and leds soldered together!

Total time, about 2 hours! Tested and working great! Total cost less than 5$!

You could add two more to the front for 2nd injectors. Had that on my 1st FC. Came on when the 2nds were activated. Just to take up some more room in the face of the box.

That's a good idea, i'll probably add that too!

I made that box in school because i wanted something cleaner than just leds and wires taped together. Was super useful to diagnose my TPS problem!

Wasn't meaning to sound like I was cutting it down. Things badass. Good work!

So just a question really I've always wanted to ask over the years but never did . Can you is just s normal light bulb or does it have to be led . May seem Dumb I know lol

Has to be LED, the transistors that switch it on and off can't support more than 150mA. A light bulb would exceed that by an exceptional factor.

Thank you sir
