This is great forum. Have learned alot already. Any way............ I would like for my fog lights to be the DRLs like theXLSs that have HID head lights. Is this a "programming" issue or is there a way to switch the trigger wires for the two lighting systems ?

 

Couple of issues:

1) You need to have the ETACS-ECU reprogrammed.

2) You need to move the fog light relay to the driving light relay position. Its detailed on the inside cover of the engine compartment fuse/relay box.

3) Change bulbs and put in 27 watt driving lights rather than the 55 watt power wasting foggies.

 

thanks rdenis. i will get the programmind done. i will be able to do the rest.
does any one have an idea what a stealership should charge for the programming ? I am located in so.cal.

 

So what happened? did you ever get this done?
