Ya the main wiring harness is on the LH side, and the horn and LH impact sensor are together in one. That is what confused me because it was clear cut something was wrong with the harness because the horn and light were on before. Now, after hitting my horn repeatedly, it works. So, I am just left with the sensor. I cannot find a ground on this thing anywhere, as it travels through the core support and into the fender.
I am thinking it is probably the sensor because the harness to the impact sensor disconnects right on the inside of the core support, which they probably just did. So, it probably isn't wiring.
What I am wondering, can you test an impact sensor to make sure it is good? I am not sure what happens to one when it goes off....
