Has anyone added a factory keyless entry pad on their 2010-13 FTC van w/o issues? I want to add one on my van but have seen 2 different part numbers and something about 2014 or 2015 FTC van being compatible?. I have the factory keyless entry FOB (three channel) like other 2010-13 owners and single channel (single button) Ford add on remote start. Any suggestions and thanks in advance.
