791xv install upgrade on civic

i got some question before i start with my install.   currently i have a 550 esp with remote start on my 2000 civic si.  i got a really good deal for a 791xv and i bought it cause i been wanting to upgrade to a pager.  people told me it is a easy upgrade.  comparing the two different alarm wiring diagram.  the 12 pin harness is the same so its plug and play.  same goes for the velet switch harness, 3 pin door lock harness, and led light.  the other harness are different but most of them are near each other and labeled the same so it pretty much simple to wires those up.  these are the ones that are not the same on the new alarm. so im not sure where to wires these up.

ORANGE / black 200mA anti-grind/ground when armed output

blue/white (-) 200mA 2nd status/defogger

GREEN / WHITE (-) factory alarm rearm

for the relay satellite im not sure where to wire up any of them wires.  and why is there three 12v constant input on one harness?

here are the pictures of the wiring diagram that i been looking at and trying to figure out which wires are easy install and which i have no clue on.  sorry if the pics are too big.

791xv

you have to take the old relays because the new brain it has different wire, you can not use the raimbow wires for the 550.

if you using a 555u or 556u you have to use the blue/white (-) 200mA 2nd status/defogger to activated the 555u

ORANGE / black 200mA anti-grind/ground when armed output

GREEN / WHITE (-) factory alarm rearm              don't use

change the antena, and there is a plug for brake(brown), tach(PURPLE / white), hood(gray),BLACK/ white,blue/white. just cut the old plug and match the colors,note: 550 it has two wires one is blue and the other one is blue/black one of those it has to be conected with the 555u.

i have the 530T already hooked up on my car.  i hope it doesnt effect the new alarm install.  since its already hooked up its already using one of the channel output correct?  im still confusing about some of the wires i mention and all the wires on the satellite relay.

Thanks for the help!
