Question:

Do you offer an adapter I can use on my 2003 Land Rover Discovery? Factory is a round plug with 4 way on the end and I need a 5way for my boat trailer. Will I also need a converter? Thanks!

Since the 2003 Land Rover Discovery has a 4-Way round connector it is most likely already converted. There should be one pin for right turn/brake lights, one pin for left turn and brake lights, one pin for running lights, and one ground pin. You can use a circuit tester like # PTW2979 to confirm.

We do have an adapter that connects to a 4-Way round but it has a 4-Way flat at the other end, # 47465 so you would need another adpater like # 20036.

What I recommend is to replace the 4-Way round connector on the Land Rover with a powered 5-Way converter, # 119177KIT, so you will not have to mess with adapters at all. Since there will be no adapters in the system there is less chance of something going wrong. That combined with the fact that there is no standard way to wire a 4-Way round (so the adapter may not work right) makes installing the 5-Way flat harness 119177KIT the best choice.
