In regards to the factory alarm system, does anyone know where the 'timer control unit' is on an 01?

 

The CTM is located behind the dash to the right of the steering collum. Pull the lower dash panel and it is mounted to the metal support on the right side of the opening.

 

Thanks, is the timer control unit for the factory alarm in the CTM?

 

yes and about every thing else on your truck if you replace it make sure you get the right one for your truck there are 4 different kinds for your truck and only one of the four will work if you have key less entry the part should be around $240.00
