The 2016-19 Utility does not use IKTs for remote start. Unfortunately Ford changed the setup on the 2016+ Utility and a VSS (Vehicle Security System) module along with a 1000' long range separate remote start FOB must be used. This is a plug and play installation. You must also install a hood switch (if not equipped see above for part #) and have OEM keyless entry (either from the factory or via my KE activation file). Contact your Ford dealer for more information. You can also check www.accessories.ford.com or such places as eBay. It uses the same kit as the same year Ford Explorer with keyed ignition. You can get kits with one way remotes, two way remotes or even cellular control. Functionality is enabled via Ford IDS. Please note the 18+ does not use the same kit as 16-17.
I am no longer selling IKTs. These can be obtained on line such as eBay. There are some Ford dealers that sell on eBay that you may be able to obtain descent pricing on. There are generic knock-offs of the IKT and I will not give an opinion on those either way.
2013-2019 Ford Police Interceptor Sedan and 2013-2015 Police Interceptor Utility also have factory remote start capabilities built into them.

To understand how the OEM remote start system works visit the Ford Owner website and download the Taurus or Explorer Owner's Manual for the year of your Police Interceptor.
