upgrade alarm, 06 charger

i need some help on upgrading my alarm system. i have a scytek astra 4000rs-2w-1 and i want to change it to a vision guard 8000, do i hook up the same color wires from astra to vision or do i have to redo the whole install? i would really appreciate the helpits a nice day 2day

oh by the way this is for an 2006 dodge charger.its a nice day 2day

If you installed the 1st unit.... use the connections you already made.  If you didn't, test first.

there are about 5 extra wires that i dont know where it would go?its a nice day 2day

oh sorry the wires that I am concerned about on the vision guard 8000 is: -the 2 battery input (red wires on the 6-pin harness) -the +12v relay power output (red wire on the door lock/unlock wire harness) -the passenger unlock output(-) (blue/white wire on the 20 pin harness. all the other wires the astra 4000rs-2w-1 has it.its a nice day 2day

Hey KTM I found a good deal on a crystal ball, maybe You Howie and I can chip in and get it.

The 2 large red constant power wires you cite there can be swapped with the ones on the Astra 4000's external relay bank. If the Astra works your door locks now, ignore that 12v relay power wire - it's only used with a plug-in door lock relay. If you'd like the VisionGuard to do priority unlocking (driver's door on the first press, all doors on the second) that is when you'd use that passenger unlock output.C Renner's Auto Electronix

My service is cheap, quick, and good - pick any two

thanks very much i just want to make sure before i install it. i let you guys know how it works thanks again.its a nice day 2day

also i have the mp3 siren from scytek do i use the scytek mode or the universal mode? if i do have to use the scytek mode where does the blue attention(-) wire go to on the alarm?its a nice day 2day
