Can anybody post a picture for the headlight and switch with the wire color?

My van was manufactured for the US market and they are not equipped with a Daytime Running Light module. I need to know if the headlight is positive switched or ground switched in order to install a Daytime Running Light module. These aftermarket modules come in different models for positive or ground switch.

I know that the Ram trucks are ground switched for the year 2000 but the RAM Vans may be different.

Thanks.
