Expert Reply:

The Standard Trailer Light Kit with 25' Wire Harness part # TL29BK as I am sure you noticed grounds via the mounting hardware therefore there is not a singular ground wire. In order to attach this light to a wooden surface you will need to run a ground wire yourself up to the trailer tongue using the mounting studs on the back with ring terminals part # DW05705-1 and wire part # 12-1-1.

The other option you have is to use the Peterson LED Light Kit for Trailers part # V944 which does have a singular ground wire on each light. The side marker lights could then be added with the Optronics LED Clearance or Side Marker Light part # MCL36AB. This setup uses all LED lights which will last longer and draw less power than the above.
