Bobs2015EdgeSport Posted October 3, 2015 Report Share Posted October 3, 2015 I am putting the finishing connections on my new trailer hitch lighting module, and the instructions want me to run a heavy power lead from the rear of the car (where the module is located) all the way up front, and into the engine compartment (to connect directly to the battery). I've looked under both the hood and the dash, and cannot see any "easy" way to pass the cable through into the engine compartment. Has anyone on the forum had to do this yet? If so, did you find any existing passageway (or hole) from the driver's side through into the engine compartment? (With the engine going so far under the cowl, it seems an almost impossible task to get a heavy wire through into the engine compartment). Any ideas?

enigma-2 Posted October 4, 2015 Report Share Posted October 4, 2015 How about routing a water-resistant wire under the car, in a best-case, protected location? Quote Link to comment Share on other sites More sharing options...
WWWPerfA_ZN0W Posted October 4, 2015 Report Share Posted October 4, 2015 There might be an OEM plug hidden under the windshield cowl on the driver's side of the firewall. There is one on the Flex in that location, so ... Quote Link to comment Share on other sites More sharing options...
Bobs2015EdgeSport Posted October 6, 2015 Author Report Share Posted October 6, 2015 I will have to take another look under the hood, when I have some more time available... thanks! Quote Link to comment Share on other sites More sharing options...
dwayne Posted October 28, 2015 Report Share Posted October 28, 2015 I spliced the lighting module power lead into the rear power outlet. Attached is the wiring diagram. Ford Edge Rear Power Outlet1.pdf Quote Link to comment Share on other sites More sharing options...
Bobs2015EdgeSport Posted November 9, 2015 Author Report Share Posted November 9, 2015 Yeah, I did that initially too, but soon discovered that the power outlets in my 2015 Edge Sport all eventually shut-off within a few seconds of turning the key off and locking the car. This could be problematic, for example, when parking on the side of the road with your 4-way flashers going... I tested it and they stopped flashing on my trailer shortly after getting out and locking the car... this is because the power module is apparently told to shut-down by the ECM shortly after you shut-down the car. In other words, you also apparently cannot leave your phone charging in the car unattended either, apparently. (This may be why the trailer module manufacturer specifically states not to tie-in the unit's power lead to any power module, but to only run it from a lead taken directly off of the battery). I then did so and now the car no longer plays any "games", in providing power to the unit. Quote Link to comment Share on other sites More sharing options...
