Welcome to the forum. If you really don't want the "One Touch" the easiest, and cheapest
, solution is to buy a Sunseeker 2290 instead of a Forester. Sunseeker's don't have the "bling" of a Forester but are the same units, built on the same line, with mostly the same components...except the "One Touch" and some trim items.
FR does not provide wiring diagrams to customers so you are on your own trying to replace the "One Touch" with switches. While it can be done it will be time consuming to say the least.
Avoiding "One Touch" is one of the reasons we have a Sunseeker 250
0TSF instead of a Forester 250
1TSF...
