Hey Richard!

The running light function will be the wire that was closest to the ground pin on the Curt Auxiliary LED Indicator Lights # C53201 4-way connector. I haven't stripped back the cover on this kit before so I don't have any hands-on experience with what you're doing, but I can say that the ground pin is the covered one and then the next one next to it is the one you want to connect your registration plate light to.

Attached is a photo of the vehicle side pin out for a 4-way connector for your reference.
