Hey HUMTECH. Sounds like you can answer this question. Check this product
http://www.autoloc.com/detail.lasso?itemid=WC1000 I'm going to install it on the sunroof circuit for one touch open/close. They say it will work. It just goes inline on each open close circuit & when the appliance reaches its stop it senses the extra load and disconnect. I just want to be sure it won't screw with the Hummer module. Got an opinion?
