Hello I will answer your question,
If you remove the three bolts and the connector that attach the wiper motor to the cowling in the engine compartment and lay the motor on the bench you will see two small screws that secure the cover of the pulse board cover. Open the cover and slip the board out ad the new one in. then put it all back in the truck. The new module comes with directions. Part#88136
Its a piece of cake
Can you just undo the module?
Or is it this type?
Depending on which wiper motor you have I show two dorman boards a 906-136 and a 88136 that I cant tell apart by the pictures and both are speced for your truck.
Im afraid you are going to have to get with the part store and match your module to what they have in stock.
OEM p/n #12463090 If you have the second type check the connector and see if it matches your old one If it does it should work.
Do you have the number off your new module? Maybe a side by side picture of the connectors? I will see what information I can get for you
