hi i have a 93 f150 without fact speed control/cruise. i had a 96 with factory cruise that i removed the servo from and steering column. i put these in the 93 and have verified all the wires are connected to the right place from the buttons back to the servo box, however still no working cruise.any ideas was there a brake pressure switch for this year? if so where would i find that plug on my 93.the main harness for the servo was right there easy to find. thanks for the help
