Wiring side step lights to the cargo lights (after diode mod)


Recommended Posts

Posted

I'm sure this has been asked before but I can't seem to find it.  What I'm finding I love and at times hate about this forum is the abundant wealth of information and that can make it hard to find a specific answer.

 

Anyway, I'm a happy new owner of a '18 Z71 and I've taken off with some of the many mods that folks have done to improve the truck.  I already did the diode mods to have the fog lights on with the headlights as well as the cargo/factory bed LEDs on with the reverse lights.  This weekend I plan on putting in some interior lights, maybe augmenting the bed lights and I have some ribbon LEDs on order for step lights.

 

Now, my question is about wiring the step lights.  I have seen where folks are wiring them to the gray wire so they come on with the dome lights.  I was just wondering of there would be any pros or cons to instead wiring them to the cargo lights and if that was easily done from the underside of the truck.  

 

I guess my thought was the lights wouldn't come on at night if you are driving down the road and someone turns on the dome lights.  Maybe this doesn't happen anyway which is why I'm asking.  I'm probably overthinking it but figured I'd ask those with more experience.

I understand what you're saying about the form having a wealth of information, my pet peeve would be the same as yours Plus the point that so many times people ask questions about a problem described a problem and then they said they fixed it but they never say how they fixed it, or follow up on something that's been in a thread forever. Everybody's input is important and everybody's repair result may be different trying to achieve the same goal. But that's the internet

I had mine wired to cargo but when I got a canopy on I could no longer use diode as it would be too bright in the back when backing up.

So I used the rubber gormet near driver side door and ran my wiring through there then to the 4 door step lighting.

Now it’s on dome light circuit and I love how it all turned out.

Thanks for the input. So did it function differently when you had it wired to the cargo light? If you didn't have a cannot anymore, would you go back to that wiring or keep it as it is?

Leave as is; it’s hard wired in which I would prefer. Very easy to do this as well.

Right, I just meant function-wise. Do you like it better hooked up to the dome lights versus the cargo lights?

When I had it wired back to the cargo lights, I had to run two diodes.

1 to have cargo lamps go on with reverse lights
1 to have reverse lights go on with cargo lamps

This allowed me to get the cargo lamps (along with my step lighting) on when I locked or unlocked the truck.

But when adding the canopy, like stated I couldn’t do this anymore.

I can’t remember if when I had this done if the lights would turn on ANY time doors would open.

But I do know the step lighting system fires on perfectly when doors open if I tie direct into the dome light circuit.

Any chance you have photos of how you ran the wires through the grommet?  I think I found the grommet you speak of but I just want to be sure.  For the passenger side, did you just string a wire from the driver's side or did you run a separate wire from the passenger side through the grommet over there?

I’m away working, it is right under the driver side floor area by door.

I ran passenger lighting from that circuit coming from driver side. Very easy mod.

I mounted an LED strip above the running boards per wifes request. They come on when hit unlock button or open doors. I stuck a long screwdriver through the grommet and attached wire then pulled it through then tapped into dome lights. Overall easy mod and pleased how bright they are and wife is happy now that she can see where she is stepping. d65b883da3beb189f51d7a66b03232c0.jpg

Gotcha. So I guess the only thing I'm left wondering is how you strung the wire under the truck to the passenger side. Any tips or things to be wary of? Probably be doing this mod this weekend. Thanks

I ran mine through the cross member on the frame, takes time and patients but it will go through that cross member.

Thanks fellas.  Got the install done yesterday.  Not as clean as I'd like it but I just wanted to get it done just to make sure everything worked and I liked the lights I chose.  I'll go back and tidy stuff up later.  Overall, pretty happy with the results.  Both the step lights and under dash/seat lighting inside.

Looks just like mine, a job well done brother.

    • I'm not sure if this should be a new topic, let me know if it's out of place. This my first post. Thanks 85077522 - AC Delco GM Genuine Parts Brake Master Cylinders. Anyone else had to replace this brake master cylinder yet. I didn't do any brake work, it looks like new parts and I've had the truck for about 4k miles, 119k total miles.  When it started to throw codes I did the calibrations with a bidirectional scanner and got the codes to clear but they came back so I did the routine; base bleed, automated bleed and final base bleed. All that with Bosch ES16-32N fluid (please look it up). That seemed to fix it but 100ish miles later it failed again so I ran the same process but with a pressure bleeder this time and got the same results, fixed for 100ish miles. The original fluid looked bad and I thought I got most of it out, it could've been the wrong fluid. The codes; P25A2, C05B0-00, C2A1B. I can get them to clear but not for long. The C05B0 indicates a leak in the front circuit (which is bone dry) so I'm thinking of doing the bleed process on that front again today and I don't know if that's taboo to just do the front but at this point it seems like it's worth the try anyway. The new master cylinder/module unit is supposed to get here today. But now I'm pretty much convinced this install is over my head. I've called several shops and some mobile guys that I know but this thing is like radio active material, scary wise. I did get 2 local shops say they should be able to do it, one says he has the SPS2 programing capability. And with the battery disconnected is there supposed to be pedal resistance, mine is to the floor, then if I pump it I can get some resistance. I had a panic stop prior to this issue which may have contributed from what I read. And on the first attempt to bleed and hydraulic test the scanner listed things to look for and one was any gaps between the pad and rotors which I did notice on the RF corner and I removed the outer pad (where the gap was) cleaned it and the hardware and didn't see a gap after that but will re-check it. I read that if pushing the caliper pistons back then you're supposed to open the bleeder so as to not push fluid backwards into the abs module or it will damage it. If that's true then that's also a possibility from the previous owner having the brakes changed before I got it. I'm using an XTool ip500 scanner. Any suggestions, questions and comments welcome. 
    • Next Friday will be my 6 week point from my right knee replacement.  The surgeon says it will be fine if I choose to drive after this checkup.  I know I could drive now but best to do as my surgeon (and my wife) tell me.  Richard compared being 62 to 72.  I remember when I was in my early 60's I was experiencing slow but regular decline in my mobility.  Thanks to good medical support,  i continued to fight the speed and spread of this decline. During my 60's I worked on non-surgical methods and just when I turned 70, my orthopedic surgeon recommended joint replacements.  In a little over a year, I had one shoulder and both knees replaced.  This hasn't been a terribly fun experience, but worth the discomfort as my future mobility health trajectory has reversed.  It is a treat to now be watching my mobility. balance and confidence steadily improve!
