keyless entry security kia soul

I purchased ultrastart 450pro on the cheap and looking to install on my 2010 kia soul base, no key transponder or factory alarm/keyless.  Ok drivers kick panel is the location for most wires correct.  Does it matter if i hook up windows negative before the door.  Any information would be helpful ive never installed keyless entry but have done quite a few car stereos,boat electrical.  Would posilocks be suitable and ok blue ones.

Here is some inforation on wires
