Chris Duke: I am Chris Duke and this is Motorz. One of the more challenging installs that will make a vehicle owner open up his wallet and run to a shop is a car alarm installation. But here at Motorz we are not afraid to try anything including that despite not finding any information online, but a stock wiring diagram, we think we figured it all out. So today on Motorz we are going to install a Viper 5900 car alarm system on our 2008 Ford Mustang GT which came from the factory without a stock alarm system.
The installation of any car alarm system is externally difficult and the Viper 5900 is no exception. There is just a lot to hock up. But we are gonna show you how to do it. The kit comes with the main harness right here, comes with a relay harness, a siren and a hood pin that goes underneath the hood, a two-way remote, this thing will work from up to a mile away from your vehicle, a shock sensor and an antenna. Now you can refer to the manual, it tells you what each wire is for, which you are gonna need to pair that with the information that you get from your stock wiring diagram to figure out where that goes inside your vehicle. Now we already did that with all these wires, we labeled which one goes to the junction box and which one goes to the ignition area and which color wire it connects to.
The tools you are gonna need for this alarm installation include a flash light, a power drill, you need a couple of drill bits, one for the hood pin and a smaller one for drilling some powder holes for that siren. Some dikes and some wire strippers, you are going to need some extra wiring, some electrical tap, couple of screw drivers or Phillips and flat blade. You need a Torks 2.5 bit, some tape to mark your wiring, crescent wrench, some solder and soldering iron and some heat sink tubing or you can do what we are gonna do and use some Posi-Taps. You are also gone a need a 10 millimeter deep socket and a serious of sockets ranging from six millimeters all the way to ten.
Once you've disconnected the positive lead off your battery terminals, it's time to get to all the wiring inside, now this a very complex installation so, we actually installed this alarm the other day to make sure it was operational and make sure that what we show you is correct. Now there is ton of wire is here, there is a whole bunch that go over near the ignition area underneath the steering column, there is a whole bunch that go over here by the smart junction box which is in the passenger side kick panel. To get there you need to pop of -- that's right here. Once you got that out of the way, the kick panel also just pops off. Here is your smart junction box, right in there. You are going to need to get a 10 millimeter deep socket to get that off because we do need to connect the whole bunch of wires behind there.
It has to be just kind of hung on there at the top of some clip so you need to pull it out, unclip it at the top. We need to get behind this junction box here, but there is this harness in the way so pinch both sides of this, flip this down and this guy comes out. All these wires what you need to get to obviously since we already installed this alarm to make sure that were showing you what is correct, we have all these Posi-Taps connected with the correct wires.
Now these Posi-Taps make it really easy to work in tight situations like this where the wires from the -- are short and you don't have much room to work with. Now normally the best way to do this would be to use a solder and some heat shirk tubing and everything else. These Posi-Taps are just as good once you got that in or tug on all that to make sure that it's not gonna come out.
Now we are going to go head and hookup the rest of wires here behind the smart junction box, once we are done with that, we're going to hookup the brain and the shock sensor and we are going to go take look at the wiring over the ignition area. Now if you've got a 2005 to 2009 Mustang without a stock alarm system refer to the following information, but if you do have a stock alarm system you gonna need bypass that first.
With all the wires connected to the back of the SJB we've got a route to siren wire, a 12 volt power that we need as well as the hood pin and this wiring harness for the ignition area, we need to route all of these on over behind the dash right back here. You know -- comes time to wrapping everything here on the passenger side you wanna to take your brain and you wanna hide that somewhere outside, so nobody that's breaking in your vehicle can find it. Hide all the wiring, and you want to take you shock sensor and you wanna mount that on to something metal, so if someone hits your car it will vibrate and trip the alarm.
Then finally we are going to take this cable, we are route it up to the A pillar up to the headliner where we going mount the antenna. We mounted the antenna right here behind the rearview mirror and the way we get the wire back there, you just pull down this headliner a little bit, stuff that wire up there all the way over to the side, this piece of plastic that's on the A pillar that just pops off and the wire goes down the side behind the dash.
Over underneath the steering column there is two torks 2.5 screws, you need to remove those in order to get this bottom plastic panel off. Now here underneath the steering column the ignition side is right over here on the right where you put your key, starter side is over here on the left side. So whole bunch of wires back here in a wiring harness. What you want to do is press the clip that's right over here on the outside of that, hold that harness on out. As you can see we now have easy access to all the wiring and you can also see, we have already got all these Posi-Taps on here because we've wired it already.
Now we just need to connect their wires up. As it comes from the factory this green wire right here needs to be cut which we already did and we put two Posi-Taps on there, because with this particular application this Viper alarm we need to connect up this purple wire to the starter side and this green wire goes up to the ignition side wire. Then go ahead and make the rest of your connections and then hide your wiring.
To connect the hood pin and the siren which needs to be out inside the engine compartment we had to find a hole to the firewall, we find to -- located just below the break booster, we were able to poke a hole through the carpet to get some new wire through connected up to our wires that are going to alarm.
With all our wiring inside done we need to hookup the siren and the hood pin in the engine compartment. So the siren is gonna go up right up here against the firewall and now right there facing down and then our hood pins gonna go right here in our pinch weld.
One of the things we are often criticized about using on the show are these butt connectors when it comes time to do our wiring on the electrical aspects of the vehicle. Now the criticism is that that they are not that safe to you use because the wire can sometimes pull out which is true if don't pinch it hard enough. Now the correct way to do it would be to use solder and the heat shrink tubing but that requires whole bunch of extra effort that we just don't have time for when we are shooting a show, we trying to get it done. So we found a product called Posi-Taps and it's from a company called Posi products and the way that it works is that instead of crimping it like in the traditional butt connector is its pinched with the twist on type of method.
Now it comes in different sizes like this 10-12 gauge, a 12 to 18 gauge and 20-22 gauge and I'll show how this works. You take your wire that would be typically inside your vehicle, you untwist that, you slide your wire over like that and you twist it on. This is the wire that's typically inside your vehicle, you really can't get to, it's up underneath the dashboard or in a tight spot inside the engine compartment, that's the one that you want to pinch it too. You take your other wire the one that you wanna connect it to and you strip the end of it a little bit, you push it in and then you connect that by twisting that on, so like that. Once you've got that you cannot pull that out and this does not slide it's pinched in there pretty good.
So that's what we're probably gonna be using from now on, hopefully we won't be criticized, I recommend that you check it out. Go to www.posi-products.com and check out the Posi-Taps as well as their other line of products that are similar to this one.
We have the option of programing the system, but all the factory defaults were just fine for us. Now installing a car alarm is basically the same for all vehicles, where it gets really tricky is figuring out the OEM wiring that's where we return to the12volt.com for their help as well as Mike Miller at San Diego Car stereo. Well that does it for this episode of Motorz. For more episodes head on over to www.motorz.tv and be sure to request a free sticker for your ride and check out our forums.
