Hi, I tried to install my backup camera but sadly when I put my multimeter in the purple cable for the reverse sensor but it did a shot circuit and now my car doesn’t start. It turns on everything but when I try to start my car the light goes off and back on.

Please help with this. I tested the fuses and they are good, the only thing missing is test the ignition relay but I can’t find it. My reverse light don’t go on.

 

Check the fuses in the IPDM.
