Ill make it easy on ya.
Get:
2x rolls of electrical tape($1 each)
1x soldering iron ($25 for a wireless one at canadian tire)
1x roll of solder (flux core) ($10 for a big roll, your new, so your going to waste alot at first)
1x voltmeter ($15 at canadian tire, you want one anyways if you dont already have one)
1x roll of the smallest wire you can get, 22 gauge will do, its not important really (except for doors, should be a bit bigger maybe, but again... not really THAT important)
1X wire strippers with a cutter, or you can just be hardcore like me and use sissors and the little space between your eye tooth to strip it
and you should be good to go.
Do these steps first and post back:
1. Mount the Unit (dont connect it just yet)
2. Mount all the other easy to connect standalone stuff like the reciever and shock sensor
3. Find a ground (or just take a bolt out and sand the paint off until you get metal on metal contact) (use the voltmeter to make sure) hook up to BLACK (duh)
4. Find Constant power 12+ all the time. Hook it up to the RED wire
5. Find 12+ power ONLY when the cars running, it will probally be easiest to find it under the steering wheel. Hook it up to YELLOW.
NOTE
Dont plug in the harness yet. Just mount the unit and run the wires ONE by ONE to where you want them. Solder it up after testing.
TEST IT BEFORE AAAANNNNNDDD AFTER YOU RUN THE WIRE, SHIT SOMETIMES GOES WRONG BETTER TO FIND OUT NOW.
At this point your keyfob should be making a connection to the reciever, if it is then GREAT your well on your way.
At this point you should not have had to make any cuts or drill anything in your car, later you can poke with wire through the steering boot (some shops even do this eeew) or you can just drill out a small hole and put a $0.49 grommet on there and run the wires through there
