Rear sensor issues after swapping bumpers.

Hi all. I had an opportunity to upgrade my front and r ear bumpers taken off a brand new raptor. So I did. Looks great, however the rear parking sensors are acting up. I did notice that the mounting holes for the raptor sensors were positioned a bit different and I had to make some adjustments when I was swapping them out. Now every time I go in reverse every sensor in the back acts up regardless if there is anything close by.

How would I go about adjusting this. I have tried to move them but it’s still acting up. I can get new sensors that are for the raptor but not sure that it will be compatible with my pcm.

Yeah, I had very similar rear bumper sensor false alerts after installing ARB bumpers. Our problem was the rear main wiring harness' connection was really packed with dirt/grit/sand. I had cleaned enough to re-install after the bumper switch, but it still didn't have a great connection.

So, after some 'quality time' re-cleaning those connectors with pick, tooth
brush, compressed air - Sensors are fine..

Cheers

In my case my bronco had 1200 miles on it when I done the swap. All connections were very clean so I dont think thats the issue here.
