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.
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.
