so i finally started to work on it today as some contractors were working to fix the water leak in the garage (had to be there to "supervise" the job)
anyways, I had enough time to run the wires, find the ground, install an on/off switch, install light in front passenger foot area, created a short circuit as i was turning off the light when the car was on (not sure if it was a short circuit or what, but the car engine immobilizer just kicked in, immobilizing the engine. had to reset the car to fix the problem)
my guess of the cause of the problem is that i didn't have fuse for the floor lights. i just tuck the wire with the fuse into the fuse slot, and ground the ground to the bolt that secured the front seat. (that happened to be the only place i can find to ground inside the car, on the floor.)
the on/off switch is wired as positive (or should i use negative for on/off?) before the first LED.
this set up only works when car is on. it does not turn on with the doors open.
however, i will try to wire it like this set up tomorrow (or when i figure out which diode i need)
since i dont have tints on, it is going to be pretty bright when looked from outside. not sure if its the look that i want, chances are i will paint them green to match the exterior color if i decide they are too bright for night time driving.
