Thanks for the reply wab! I'll check it out tomorrow to measure the drilling point, so we don't have an existing factory firewall on the cmax right? What about all the cabin fuses wiring that goes to the battery main fuse at the engine Bay? Do you think I can squeeze some wiring in there? My dealer have installed a Ford oem remote starter when I bought the c-max, I seen some sort of white cable goes along on the hinge of the hood then all the way down to behind the brake assembly, do you think they already make some sort of firewall somewhere to get the installation done? If I use the drilling method, do you use any hydraulic jack to lift the car up so you can pull the wire from underneath the car? And one more question :) What fuse do you think the best for me to add a circuit for the laser jammer CPU? My option right now is the radio which has 15A with it, and the next one would be the cigar lighter fuse with 20A. This will be a big help! Thanks a bunch again! ;)
