Rancher Newbie - Permision to come aboard?

Hello everyone , just bought a 2009 Rancher ES with power steering brand new , i think i may of over paid for it tho because i had nearly $8,000 in it counting the Warn 2500# winch and 48" snow plow

So anyway i put the winch on today and what i did was use a posi-tap and tapped into ING wire under the fuse box , it was the far back left hand wire , thats only hot when the key is on , works great just wanted to make sure that was ok?

also how does the winch know when to stop ? will it just try to pull the hook into its self and break something?

Another Q for ya...

do you have to get the box if you get the HMF pipe or can you just get the pipe ?

been riding quads all my life , grew up on a 125M 3 wheeler and dad had to bring home 5 gallons of gas every day all summer for years .
