it shouldn't because it doesn't change anything inside that car. only right at the bulbs

The system will see bulbs on when they are not supposed to be. It changes the resistance in the various voltages and things that the system monitors. Jimmyfloyd ran into it when he swapped his trunk over to the newer style with more light bulbs.

It'* a very PITA kind of thing when you don't want it. When you do burn a bulb and it tells you right where to go..it'* a nice thing.

where is the monitor located, cuz this is hooked up right at the plug at the bulbs...

It is physically located inside the car. That has no bearing on the situation though. It knows when a bulb in the socket burns out. You can't fathom how cool it is when a bulb does burn out and you are running errands..last of which is a trip to the parts store for a new bulb.

Forget the other errands and head to the parts store

WTF? you are dreaming about the darn thing!

Yea, it was pretty easy to do that mod. Basically, all you need is a relay, and some wire (18 gauge works).

Basically, here'* what we did....

The relay'* solenoid is connected between ground, and the +12v of one of the high beams. So, that when the high beams turn on, it turns on the relay.

Then, you connect one side of the NO (Normally Open) contacts of the relay to a constant 12V source (the battery works well, and provides pleanty of current). The other side of the NO contacts, you connect to the +12v of the low beams.

Since the headlight switch switches the +12v side, and not ground, this works. You'd have to do things a bit backwards on vehicles that switch the ground, and leave a constant +12v connected.

So, when the low beams are on, the relay is "off", when you turn on the high beams, the relay turns "on" and the low beams are then powered directly from the battery, thru the relay. Probably a good idea to fuse the line from the relay to the battery, ours had a 15A fuse (used a cheapo driving/fog light leftover wiring harness).

And, yes, they are legal. Case in point: My jeep. I have 9006/9005 bulbs (of the XS variety) and my low beams stay on with my high beams. So, if it'* legal for mine, it would stand to reason that any 9005/9006 setup would be legal.

If you're not familar with relays, here'* what you connect the terminals to:

30 - +12V (Battery)
87 - Low Beams +12V
86 - Ground
85 - High Beam +12V

wow, i tell yah, i know alot about computer wiring and such, but that was just downright confusing, i wish someone would do it for me ive always wanted to do that, or something like wren did, keeping the fogs on with the highs or all of em on at once...VERY COOL!!!

doesn't that REALLY tax your alternator? i only have a 105 in my car, i don't even know if they make a more powerful one for my gen....

Wj..not sure about the alternator and the amount of draw. It would need to be checked out for sure.


Here is that thread about the lamp monitor that I was mentioning. Lamp monitor issues with all 4 lights on
