Neither the servo nor the sharp ir need pulling low by default. If you use a servo correctly then the signal wire is constantly being altered. The sharp ir signal wire is an output wire so you shouldnt be controlling it at all, it just contains a varying voltage.
can someone help me out with this i plainly need to connect these things to my PIC MCU on my own homemade board.
Do you mean how do you physically connect them ? if so then well need to see a picture of youre board
or do you mean where to connect them on the PIC? this depends on which port you want them on. The sharp ir signal wire wants to connect to the portA0 pin most likely (being the first analog pin). The servo signal wire wants to connect to a general i/o port like portD0.
