Step Rail Lighting
After reading
this thread, I decided I really wanted to do this mod. So, over the weekend I spent a few hours (okay, more like 8 ) completing this!
It took longer than anticipated, mainly because I spent the first three hours planning and then going about it the wrong way. At first (per the thread I linked), I pulled out the Smart Entry Control Unit and was going to splice into the Red/Black wire that controls the dome light. After figuring out that wire was way too short and it wasn't going to happen, it was back to the drawing board... I thought about it a little bit more, and realized that wire goes directly to the dome light, most likely via the A-pillar. So, I popped that off, and bingo!
You can see my soldering job there. I spliced in there, ran the wire down the A-Pillar and behind the dash, under the carpet and through the wiring harness corridor to this drain hole:
I put the plug back in, but I may need to put a hole through the middle of it then silicone the wires into place at the hole. We'll get back to what I 'need' to do soon..
With the interior wiring (mostly) done, it was time to put the LED strips on and work on the underside.
I don't have a lot of pictures of this part. And, even if I did, I might not show them to you because the wiring job I did down here is seriously,
truly, terrible. I badly need to redo it. It will hold for now and there's no shorts, but there's a couple 2" splices and inappropriate zip ties I'm not proud of. It's one of those measure twice / cut once scenarios, only I didn't measure at all.
The bottom part was straightforward. The connection running from the Dome wire gets split 1-->2, with one going to the driver side and the other to the pax side. I ended up having to run another wire through the cab, and into the dome light's fuse. That's another thing I should re-do... I will eventually hook that wire up to constant power and put an inline fuse instead of relying on the dome light kick panel fuse.
Final product:
These lights are completed controlled by the SECU.. when I unlock with the key fob, they turn on. When I lock with the fob, they turn off. When the door opens, they turn on, if I don't lock it they turn off automatically after 1 minute. Basically, exactly as the dome light operates except I don't have manual control.
