valet 561t programming

i can enter programming mode with the switch,how do you change the options? trying to change from tach sense to voltage sense. this is in a 2001 ford explorer. it will not pick up tach signal.double checked wire violet/wht to tan / YELLOW on truck @ecm under hood.searched the site someone else asked the same,but did not see a response.if i need a valet remote will one from a 562t work? thanks             georgernemtb

once you are in the feature channel you want you use your activation input to switch to the next setting ex. once in programming mode for feature 2, press whatever you would to remote start (usually installers hook it up to lock, so hit lock on the key fob)Note: You Always Dont Get What You Pay For.

thank you will try that georgernemtb
