Hey Chris, according to the manufacturer the TruXedo TruXport Soft, Roll-Up Tonneau Cover # TX248601 is 80" long, and since this fits the flare side it's going to taper toward the tailgate, so it'll be 58.6875" wide in the front and taper to 51.8750" wide. view full answer...
I do not see any reason to be concerned with the installation of the Tekonsha Voyager Trailer Brake Controller # 39510 on your 1999 Ford-F-150. Since you have the factory wiring for the Tekonsha Plug-In Wiring Adapter 3035-P the correct wire has already been terminated to the factory plug.
The red wire with green stripe will only come into play when you are hard wiring in a brake controller. view full answer...
