I can supply the parts to add interior 12V ign wire without voiding warranty! - I am wiring in multiple accessories to my 2008 Silverado LTZ (interior lighting, in-car camera, ...

I am wiring in multiple accessories to my 2008 Silverado LTZ (interior lighting, in-car camera, GPS, etc) and spent a lot of time researching the proper way to do it. I found the way GM does it when you take it to a dealer for an install of some aftermarket interior electrical accessory. I was about to buy the parts to do it, but realized if there are more people that are interested, it will be cheaper for us If I do one group buy (as shipping costs is the same if I buy 1 or 50 of these). So I wanted to see how many people are interested.

Basically I will be buying a plastic connector that plugs into the MBEC under the drivers side dash, it has a spot available specifically for when GM adds aftermarket things (connector X14). This available spot includes a ground pin, constant power fused pins, an ignition pin, and a RAP pin. You can use whichever ones you choose to hook up your interior accessories. I will also be purchasing the extra small female pins that you will need to put into the plastic connector. Then you just run your wires!

Personally i will be using the RAP pin, and running that to trigger a relay, then the relay will draw power straight from the battery to power a distribution block with multiple fused circuits. This way my entire distribution block is RAP accessory triggered (on and off with the ignition and doesn't shut off until the driver's door is opened like the factory radio) and I can power multiple devices with each device separately fused. Note: if you do decide to use the RAP (retained accessory power) pin, you MUST run it to a relay instead of directly to your devices as it is only rated for 300mA. If you do not want to use the relay, the other ignition pin is rated at 15A. The constant power pins are rated 30A and 15A depending on which one you use.



If you are interested, just post on here letting me know. Once I see approx how many people are interested I will post the prices and collect payments and order the parts and send them out to you. Expect the connector and the pins with shipping to be approx. $20 total.

If you want the same setup as I am doing (connector, pins, relay, distribution block), I would estimate approx $65-$85 total

Nevermind, I went ahead and ordered the parts I need. If you are interested in how to do this or where to get the parts you can always post on here or message me.

Honestly, this is a pretty common issue/question. If you could take some pics and notes of your install... And write a how to, you would be helping ALOT of people!

I most certainly will write up a detailed how-to. I will be installing truck bed lighting, side step lighting, rear view camera, and GPS all at the same time to be run off the power that will be attained this way. The lighting will all be triggered by standard door pin switches and will have override rocker switches hidden somewhere. It will be a clean install. I'll let you all know when I get the how-to up and I'll post the link in here.

Unrelated: I will also be installing a new radio head unit and xm receiver (using factory xm antenna) that way I retain ALL factory warnings, chimes, OnStar, steering wheel controls, and xm functionality...and replacing my front two door speakers again with better quality Focal speakers and taking out my Kicker speakers.

I follow you to the "T"... this is going to be an involved install...

Major how to work lol! Thanks! The parts list and numbers is the nice part!

Looking forward to seeing all your hard work! Good luck!

Subscribed! I make those terminals

I wanna see. Just for future reference...

Everything worked well just as it should. I never did a thorough how-to but here is another thread I started with extra pictures.

Added new stereo/lighting/etc
