one more power pack question

This is for the intruder 150 model e150gletr. No parts place I call seems to
know anything, the ones that do, do not have all the parts. can someone please clear this up for me before I lose my mind::
what I think I need.. sierra pack #18-5887
optic sensor part 18-5884
Do I need plug wires for this pack? Can they be purchased at a local auto parts house? Which wires(part #)? where to order?
Serial number for motor was go3154819

never mind.................

OK I just got done looking up the info for you too. http://www.bassboatcentral.com/smileys/doh.gif
