I tried my new wiring harness out today. I ended up using the butte connector to military plug pin method, as the 2 military vehicle side plugs I had were too far gone. The turn signals were great, but the parking and brake lights were very dim - too dim to use safely. I know it is supposed to be for temporary use, but I just went ahead and used the towing lights instead. The trailer side plug I used was an old one, so I'm not ruling out bad wiring, plus I've been sick the last 5 days, so I'm not ruling out user error! I'll try it again tomorrow if it's nice outside. I still want to mount a military (vehicle side) plug in my bumper and the pintle where the license plate is.
