Courtesy Rock Lights

Hello,
I have been looking at installing rock lights and found DSIM’s plug and play kit, which allowed the rock lights to function as an extension of the third brake light “cab light” switch. This allowed the rock lights to be manually turned on with the on position, or used as a courtesy/door light with the middle position. From what I gather it seems DSIM no longer is producing these parts and they are out of stock. Does anyone have any experience recreating this set up, or would anyone be able to point me in the right direction if this has already been addressed? This my first lighting project and I have no experience with vehicle electrical systems. TYIA

They make in-line illumination spliitters that power the back lighting for other switches. Just use one of those to power a relay, controlling the underglow.... I mean "rock lights".

Might want to page @Puppypunter if he makes you one, he can make me one too… please.

 

Tag me in the morning so I remember to look into it. Definitely something I can make

 

A switch is a switch, you could get a normal 3 position switch. What matters is the wiring

Thanks @Puppypunter

 

So 9 is grounded when the cab light is on, right? This brings back memories

 

At unlock/lock.

 

#5 (BLUE) is parallel to cab switch position.

 

All those pretty colors, but alas, what does it all mean?

 

Following, except for the relay component, would anyone be able to expand more on the relay set up?

 

What are your questions?

 

Im unfamiliar with relay wiring in general, and the diagram is unclear to me what wires are run to the relay. If you are able to clarify that as well as what sort of relay is used, or any links to useful information regarding learning about relays please.

Relay - Wikipedia

The most basic thing is a "Relay is a switch" that must be understood first of all.

 

So i see one wire running from the relay to the lighting devices. The lighting devices will have two wires, where will the ground/neutral wires be run to?

 

depends, if ground wire kept near install, then any near bare metal bolt. If ground wire runs back into cab, many choices there. No neutral on a DC circuit.
