Help with interior light connections

Hello everybody just have a few questions if anybody wants to help out. I had just bought some interior lighting and was just wondering if anybody who knows about electrical components could give me some pointers. I want to set up the lights so that they turn on with my headlight switch. After a lot of research i have found a fuse in the power distribution box that controls the fog lights (Fuse #58 15A). The interior lights are all connected to a control box with a switch already. Would it be wise to have the red power wire, which comes from the control box that came with the kit, tap into this fuse?

Also, if i was to do this, which side of the fuse would i tap into? I know not to bridge the connection but i did not know which side of the fuse would work correctly, and whether i need to add an in line fuse if i do tap into the fog light fuse.

Thanks in advance for any help

What kind of interior lights? Ambient lighting? And are they LED?

If you are working with ambient LED interior lighting you can just tap into the wire inside the console that supplies the lighting for the automatic's floor shifter gear position indicator. If you use this wire, they will turn on and off with the headlamp switch the same as the dash lighting. It will also use the instrument lighting dimmer switch and go on and off with the remote keyless entry. On manual transmission vehicles the wiring is there but unused.

The best way to find the fused side of a fuse is to pull the fuse and check for voltage at one of the connectors the fuse plugs into. The one that has voltage supplies the fuse and the one with no voltage is the side that goes to the source that operates with the voltage passing through the fuse.

Wiring it the way I suggested will allow the interior lighting to operate in the parking lamp on position or the headlamp on position. If you tap directly into the fuse for the fog lamp circuit the interior lamps will not operate with the headlamp switch because the fuse supplies voltage constantly before it is switched or passed through a relay therefore your interior lights would be on all the time because the circuit has not yet passed through the headlamp switch. In other words, voltage does not go through the headlamp switch first then the fuse box. It's always battery to fuse then switch so in order to have switch operation you have to connect to the output of the switch not at the fuse.

Fuses in the fuse block are either hot all the time or switched on only by the ignition switch. You have to find voltage after it passes through the headlamp switch if you want to control your interior lights with the headlamp switch. If you wish to use a dimmer, it has to be tied into the instrument panel lighting.

I installed my own ambient lighting a few years ago and you will definitely want to run it through the dimmer switch as the lighting can be too bright at night while driving unless it is dimmed enough. Since I was installing lighting in my cupholder and the back of the console for rear footwell illumination, the shifter indicator lighting wire was right there in front of the shifter with the console top removed, so it was easy to get to.

They are 15" LED tubes i got from www.ledglow.com I bought the 4 peice expandable in blue. It comes with 4 15" tubes that you connect all 4 to one control box and from the control box it goes to a on/off switch and from their comes a red power wire and a black ground wire. I wasent looking forward to cutting into any wiring under the dash or auto shifter but ill check it out and see if im up for it. I just dont want to end up cutting into any wires im not sopposed to cut into.

Just a few other questions. Seeing how your LED lights were different from mine, should i be concerned of the difference in power the LED lights need since mine come with 30 LED's per tube? Or should this not matter? Also when connecting the red wire to the PRND321 light, should i use the in-line fuse that the kit came with?

Hello just wanted to update again. I decided to take your idea but had found that the wiring would not reach the blue wire you were talking about. I had decided to connect the power wire to a Yellow wire with blue stripe behind the headlight switch and connected the ground wire next to the hood-release lever. The lights still go on and off with the headlights and also are controlled by the dimmer switch. I find it a lot easier to because if i needed to take it out i can just pop the headlight switch out and remove the kit instead of taking that middle console out.

Just wanted to thank you again watchdevel for all your help. I probably would have messed something up if i did not come here first

There is several way to wax your car The first thing is
Before waxing the vehicle it must be properly cleaned.You can use an old terry cloth (bathroom hand towel) for washing your car. There are other products on the market for this purpose as well.Look along the front bumper and backs of mirrors for bug residue and damage. Also, check directly behind the front and back tires along the painted surfaces for road tar, paint, cement, or even dried bubble gum. You should also check the surfaces of the vehicle for pine or other forms of tree sap. These will need to be removed (if possible) before waxing the vehicle.


It is the process of waxing
Removing the bugs
Removing paint
Dried cement
Road tar
Pine and other forms of tree sap

hey chris, I sent you a pm about your ambient lighting and the route you used to get it working. For anyone else, I'm thinking about getting these http://www.ledunderbody.com/7-Color-...hting-Kit.aspx

I think this would work, I just don't know what way to go in hooking it up. I read the console way, but not sure how hard it is to get there and I have a manual.

Hey that works well if you are not putting in any console and cupholder lights. The only reason I disassembled my console was because I wanted lights in my cup holder, console compartment and on the rear sides of the console to light up the rear passenger footwells. With the console apart the wiring is right there to tap into.
