2009 Acura MDX trailer lights, blower motor, heated seats

Customer Question

2009 Acura MDX. Trailer wiring pulling from trailer connector, fused, 10A, installed at a reputable trailer shop, worked fine.


 


I installed a fused, switched, hot wire to the 5th pole on my trailer.  Hot is connected to the trailer connector hot.  Again, it's fused and switched (10A).  I turn it ON when I want to disable the surge brakes on my trailer.  This worked well 4 times out.  


 


Problem:  Smoke observed in trailer solenoid, guessing caused an over current.  Neither 10A fuse were blown.  All circuits are protected going to trailer. 


 


Following this, I lost all trailer lights, heated seats and blower motor / temp controls, heating console/controls.


 


I suspected a main fuse. I checked all fuses. For sure, all main fuses by the battery are low resistance with ohm meter and appear good. Checked blower motor fuse, and many other fuses. Checked blower motor relay, opens and closes with 12V, and when switched is low resistance.


 


I need a wiring diagram for the trailer harness from battery to fuse to connector COMPLETE.  I also need a COMPLETE wiring diagram for heated seats and blower motor/temp console.


 


I need colors, test locations., or a way to trace the entire paths.  I don't believe fuses or relays to be the problem, although I could be wrong.
