Heres all the stuff I used for this project for Cupholders and Center console.
The WAGO clamps (best thing made EVER):These are $3 EACH on Oznium website. This guy on EBAY is badass sells 5 of em for $9.50
LED holders (a must buy):
The LED'S I have in my center console I bought from Fred Meyer. They were $20 but I got them on sale for $4.99. You can get them at Vatozone also - These are the ones:
^^^instead of these guys^^^ (they were only $5 so I grabbed them) you can use the LED's I used for my cupholders. Just drill 2 - 1/4" holes in each end of the inside of the center console and put 2 of the 5mm led's in.
To do the LED in the rear cupholder, I drilled a 1/4" hole on the inside of the console all the way thru to the inside of the rear cupholders. Theres a few tricks (where to run the wires) - when you flip the whole console over, you will see a space between the rear cupholders and the center console box. I ran the rear cupholder led wires down thru there instead of back thru the hole going into the center console. I will put a white LED to fill that hole later.
Hope all that doesn't sound confusing.
By the way: all of the lighting under my dash and under two front seats I did a couple years ago....that setup is this:
