No problem. Glad to help.
My experience is with the Pursuit and Prestige brands from Audiovox......but as far as I know the SRT9000 is the exact same stuff, they just use different wire colors.
--------------------------------------
Doorlocks: Yes, you can do it without relays. Need one resistor and one diode.
So, get rid of the relays.
Bring your Code's green and blue lock and unlock wires over to the Malibu's white lock/unlock wire.
Connect Code's green lock output to "band" side of diode. Connect other side of diode to car's lock/unlock wire.
Connect Code's blue unlock output to the LOWEST value resistor that comes in the 15-pack of resistors with the remote starter.....it's like 300 ohms or something like that. Connect the other end of the resistor to the car's lock/unlock wire.
If you're not able to measure the resistors for ohms, the one you need is at the very end of the 15-pack. Grab the resistor from one end of the pack, make a temporary connection........if it works, great. If it didn't work, grab the resistor from the other end of the pack.
Also, leave your locks for LAST, after the rest of the system is fully installed and functional. That way, you can just hit the buttons on the remote to verify that it works, before taping all the wires up and everything.
NOTE: I'm pretty sure that car has a feature from GM that doesn't lock the doors immediately if they're open, unless you lock them twice. During testing, you can use a small screwdriver to close the latch on the driver's door.
------------------------------
Trunk trigger: Yes, that's exactly right, except on some of those cars the BCM will false the alarm, and you'll need to cut the car's wire and put a diode inline.
You'll have to give it a try. Make a temporary connection, close up the car, arm alarm, leave car alone for 20 minutes........if it falses, use the search feature here on this site for the fix.
-----------------------------
Ignition wires: You'll get all kinds of warning lights and stuff if you don't power up the second ignition.
Pink: runs car's engine
green: runs other important things
orange accessory: runs heat/ac, necessary
brown accessory: runs minor accessories like wipers and power windows......opinions differ, but I don't connect it.
-----------------------------------
Parking lights: The Code alarm has a built in relay with plenty of power capacity.
So if the one you have is like the others I've installed, there are two parking light wires on the brain......an input and an output.
Connect the input side to FUSED constant power. Connect the output side to the car's positive parking light wire.
No need to play around the steering column. Probably the easiest place to get parking lights on that car is at the back of the radio, and you're already there anyway to do the ignition and Passlock.
