I honestly dont ever see this being an issue. You can cause them to not work but not set them off. look at pipos lexus and all those guys. you've never seen it or heard of it.
You cant clear the code its not a check engine light its gonna be on pull the bulb. or get oem pads and go from there. did you check rock auto for the oem pads?
you could if you really wanted to. Id think it would be susceptible to leaking. so youd have to do some serious glue jobbing or resin and matting the entire thing anyways.
just because you hear it power on doesnt mean its hooked up correctly. have you tried the easy way and running it write to a battery. black to ground yellow and red to positive and see if it turns on. my guess is no.
