Hi All, I got my car back after a long time away for repair and I was going to plug the trickle charger in, but found the tech didn't reconnect the positive lead to the charger dongle to the car electrical. The negative is connected, but under the + cap in the engine bay, there are 3 terminals. Which is the safe one to reconnect to. I wish I had made note of it before since the previous owner is the one that installed it. Please refer to pic. Image Unavailable, Please Login
