In your picture the orange box is the 'electronic control box' [ECU]. It is basically an on/off switch. I would disconnect the neg. battery terminal and remove the ECU from the fender. Then clean the fender and backside of ECU down to bare metal on one of the bolts, grease it, remount it, and test it. Or replace the ECU.
