hello, i'm going to install a remote starter into a 01 Jeep Gran Cherokee. i have bought a 455J for it. i don't know how does this work.

RED (+) 12V constant power input ( easy)

Black (-) Chassis ground input (easy)

BLACK/ white (-) 3 second pulsed output?????????

Green (-) arm/lock input. Where doest this one go? is this go to the remote starter brain?

Blue/white (-) disarm/driver unlock input. is this wire same as the bottom one.

Blue (-) disarm/all door unlock input.

Blue/black (-) input from remoe start. ??????????

Yellow/black data ouput. doest this wire must connect?

What about the parking light do i have the connect it. and relay , resistor require?

Factory alarm disarm do i also have to connect it?

please help

BLACK/ white - If you're not doing an alarm remote/start you don't have to hook this one up, just tape it up.
Green - Yeah this goes to the lock output of the remote start
Blue/white - only need this one if you want to do 2 step unlock.  If you do then this would get hooked up to the unlock output of the remote start.
Blue - If you're not doing 2 step unlock then your unlock output from the remote start would go to this wire.  If you are doing 2 step unlock then the second unlock output of your remote start would go to this wire.
Blue/black - would go to a ground when running output of the remote start.
Yellow/black - Connect this wire to the yellow/black (or yellow/violet) data bus signal wire
at the diagnostics plug in the truck.

parking lights yeah you will need the resistor and relay.  If i remember correctly the 455j will take care of arming and disarming the factory alarm itself, so you shouldn't have to hook that wire up.

455J does ARM / DISARM

Parking Lights:
This Vehicle Has A Resistered park Light System. The YELLOW Wire Must Be Cut And A Relay And Resistor Must Be Used. Pin 85 GROUND, Pin 86 WHITE Wire Of Alarm, Pin 87A Switch Side Of YELLOW Wire, Pin 30 BCM Side Of YELLOW Wire. Pin 87 One Side Of A 915 Ohm Resister, The Other Side Of The Resister To Ground. If Park Lights And Head Lights Are Required Use A 350 Ohm Resister In Place Of The 915 Ohm Resister.

does this way work? Pin 85 (-) from remote starter unit, pin 86 12 volts constant Pin 87 (-) yellow wire with resistor. Pin30 ground

NO........
The YELLOW Wire Must Be Cut And A Relay And Resistor Must Be Used
You need a SPDT Relay:
Cut YELLOW wire in Half:

PIN 85 = GROUND
PIN 86 = 12 Volts from Parking Lite Wire on R / S - Alarm
PIN 87 = One side of 915 ohm Resistor...The other side of Resistor goes to Ground
PIN 87a = Switch side of YELLOW wire
PIN 30 = BCM sie of YELLOW wire

There are a handful of relays above the fuses.

One of the bottom relays is parking lights---hold a screwdriver firmly against each relay, one at a time, while operating the parking lights---you'll be able to feel which is the right relay.

There is one terminal on the relay that tests as a straight ground when the parking lights are on----if you can neatly and carefully tap a wire in there, you can simply tie your remote starter's negative light-flash output right there.

I do this as well. Much easier.
