It just plugs into the side light wiring. It comes with a harness that goes in between the light and the existing built-in harness.Very nice!
Were you able to document what wires you tapped and how you installed it? I have it sitting in the garage, but havent installed it yet. Still trying to find a good way to wire it.
I can not even imagine any Subaru meeting in which this design topic came up and everyone raised their hand saying yes, what a wonderful approach. Maybe they handed off the design to the mail office person and never looked back. I would expect that it will be upgraded in the revision. Why wouldn't they simply have a highly functional light that can be dimmed? Us Subaru owners actually use these vehicles for more than going here and there.The standard rear trunk area light on the Ascent has to be the worst design element in the vehicle. Whatever idiot thought that light was a good idea should be pelted with empties.
I took your idea and made a simpler version since I couldn’t find the proper wiring for install. I have a tow hitch as well so there were a lot of extra harnesses and wiring I didn’t want to mess with.I installed the Subispeed lift gate LED and it was a huge disappointment. The light does not shine well into the cargo compartment, it mostly shines on the ground with the liftgate open. Not a good design. It also has the design flaw of being in back of you as you stand in front of the gate, which blocks much of the light.
When installing this mod, you need to remove the upper trim piece in the rear cargo area, it pops right off. As I was doing this I thought why not simply mount a dome light right here. It would then shine directly into the interior and not behind it.
So after a quick Amazon search, I found this:
This LED dome light fits perfectly on the Ascent's cargo area upper trim piece and mounts to it very easily using simple bracket and some screws. Once this is done, simply run a pair of wires to the OEM light as the Subispeed mod does. Add an inline fuse holder, then tap into the OEM wires using a couple of these, and you're done.
The resulting light was far better than the Subispeed mod and shines directly where you need it, and the cost and installation complexity is considerably less. The light looks great, almost OEM, and no wires are showing. It turns on and off automatically as you open/close the liftgate. It even has a switch should you want to turn it off manually.
I've been using this now for over a year and it works perfectly. It lights the cargo area like it was daytime.
