Sorry I took so long to get back to you.

According to my service manual, the DRLs have 2 relays, both of which are at the left rear of the engine compartment in Auxiliary Relay Box 2.

I don't have a good diagram of it, but you should be able to tell which one you need by the pin configuration.

There is also a resistor near the left side headlight, but you already found that and it's not what you were looking for.

Good luck, and let me know how it works.
