07 e90 DRL cable or coding?
I have a 2007 335i sedan. E90.
Built Sept 2006 according to Realoem.
I have idrive and am able to turn DRL on and off at will.
I want to make my AEs as DRL.
On all the time.
I have read that it is not possible to code my car for this as that is only possible in march 07 builts and forward.
Ok, but there is a harness available that is basically made up of 2 Relayss and a connection to existing harness under the hood.
Where do I buy this can't find it.
Seems like a simple power supply through relays to power on the AEs so they are on the time.
Any one have instruction on how to make this harness?
Anyone end up with errors?
Thanks in advance.
