Hello I installed a heachache rack to to my truck.
2019 f150 with blis. It was working great for 2 days until the reverse lights started to flicker. I’ve tried to remove the opt-7 taillight adapter and figured that wasn’t the problem. Disconnected the headache rack that wasn’t it. What should I look into next?

 

Check out this thread. See Post #3 for my recommendation.

Definitely something with c405. It started flickering after it rained. I looked yesterday and held it a certain type of way which would fix the issue, but how can I fix it permanently?

 

You need to carefully inspect the connector to find out what the real problem is. Is it water intrusion? Is it a bad or not properly seated terminal? If it is water intrusion some dielectric grease might help. If it is a bad wire crimp it needs to be repaired.

This document shows you how to deal with the Molex MX150 style connectors.

 

I was going to look into those connectors but now the truck is going crazy. Tpms fault, blind spot fault, passenger airbag, restraints fault. I removed the battery and they all went away, but they came back again. 😅 this is going to be wild.

 

Water Found

Water Leakage Located

Solution
SOLVED: Located water in driver side aftermarket harness, put on dielectric grease solved all issues!

 

thanks for the help and advice!!
