Auto headlights.
 

So I need help with triggering the automatic head lights. So I bought the rain tracker auto wiper system for my 01 WJ. It work well. But my problem is it will not trigger the auto headlights.

3 things
1. The option IS set to turn on the lights when the wipers are on, they do this when I use the switch.
2. I always have the automatic headlights on, when it gets dark outside.
3. So there are only 3 wires coming out of the switch going to the world. For the fromt wipers. As it stands now all 3 are being used to activate the wipers them selves. And I can not see in any wireing diagram where the wiper system interacts with the light system.

What I think my options are?
I am guess the bcm is looking for some resistance on one of the wires. I am hoping you can help me there.
Or
Can I just use the sensor on the dash for the lights themselves? If I just use a relay to ground that wire, would that turn on the lights normally.
Or
Is there some wire coming out of the back that I want.

I just would like the lights to turn on when I am using the aftermarket auto-wipers as well.
Here is what I have

Sorry, I don't have the answers you need. Maybe you can find them here. >->http://www.wjjeeps.com/lamps/headlamps.htm

Thank, i have looked at those pages before. But i get seem to find anything different at the switch from having the auto light option on and off.

Because the auto-wiper module basically acts like the switch. So it should be doing exactly what the switch is doing....humm...

Update, I have been able to find a way to use the sensor to also trigger the lights when i want. But, there is a delay on the lights if I go that route.
Also, I can't find a way to get them to stay on.
yeah...
