Remote Start Write Up
•This write up was written by me, I have referenced two sites, and used photos along with my own, and I have also altered their photos. The websites are
Bulldog Security iDatalink - Front Page
•I have noticed a lot of questions has came up on the DF about installing remote starts, and questions about the Remote start, and the bypass system.
•This write up is not telling everyone to go install their own remote start, It is easily done with experience, and recommended a 12v shop or technician does the install.
•This write up’s intention is for people who feel the need to install their own remote start, which is how everyone gets their start by experimenting, this DIY is supposed to be a outline and guide to installing and not a definite procedure, at the very least follow the Cautions and Safety instructions
•If you have criticism about the article feel free to PM me, this is my preferred way to install a remote start, there are many techniques that you can use
•If you need further help feel free to PM, I will try to help to the best of my knowledge
•This Is a basic Install guide for the Sierra and Silverado’s, I do not show any auto start units or bypasses, I simply explain what they do, how to connect them, methods for connecting two wires, and how to take apart the dash and steering column
•Last but not least, IM NOT RESPONSIBLE :)

Air bag wires are always YELLOW, and ORANGE

NEVER cut or probe the Airbag wire

NEVER disconnect the Airbag Wire from the harness

Disconnect the Batteries and let them sit for a min. to drain the power

ALWAYS work to the side of the steering wheel, with it tilted to the highest level, never work in front of the Steering wheel

This installation is recommended for a trained 12v specialist or shop, there are risks to installing an Auto start including vehicle damage, Electrical fires, and burns.

It is recommended to have either a regular or multi-purpose Dry Chemical fire extinguisher around incase an electrical fire, that is either an extinguisher with a rating of ABC, or BC

Be sure to probe with the voltmeter, and test light to make sure the wire is positive or negative, double check before putting power to the vehicle

 Double check wire charges to be sure you are not connecting a negative to a positive
 When taking apart the steering column be sure to take off the lower steering column below the steering wheel, and also the plastic that sits on top of the wheel
 The 5 wires, most important when installing a remote start are the wires from the Ignition Harness, These wires are bigger gauge wires, expect 8-10ga wires…. If they are not big wires, they are not your ignition wires
 There are several things that will result in your vehicle not starting, please continue to real the troubleshooting

• Materials Needed
 Aftermarket Remote Start w/ Diesel truck application (recommended brands- DEI, Clifford, Auto page, Prestige/Audiovox, Valiant, There are many more those are just to name a few)

 Aftermarket Bypass system- Idatalink Bypass iDatalink - Front Page - “ADS-ALSL GM” of the Solo series- This is the Model of the bypass system, that can be used for most GM vehicles, including Sierra’s and Silverado’s. To be sure which model you need, go to Idatalink’s website and enter your vehicles year make and model. This bypass system is known as Data bus Integration, meaning that all of your vehicles security info is taken from the OBDII port and automatically bypassed. This means that you can keep your door chimes, your factory locks and panic function, while being able to bypass GM’s passlock2 anti-theft system to remote start the vehicle, with the ease of connecting one wire, to accomplish all of the above functions. Be sure that the Idatalink Bypass can be used with the remote start of your choice, this means they should connect both units to each other with one wire

• Tools
 7mm Socket/wrench
 10mm Socket/wrench
 1 / 4 inch Drive w/ extension
 Pliers, both regular and needle nose
 Razor Blade
 Lots of Electrical tape
 Wire ties
 Voltmeter and test light
 Wire Cutters & Strippers

Disassembling the Dash-
 Kick Panel
 To remove the Kick panel you will need a 1 / 4 in. Drive wrench with a 7mm socket, there are (2) screws. After these screws are removed the only thing holding the panel in is snaps, you should be able to pull the panel out.

 Metal Knee Bolster
 The metal shield surrounding the Ignition harness and steering column is only held on by (4) 10mm nuts, Once the nuts are removed simply pull the metal shield off of the bolts

 Under Dash-
 Under the Metal Shield you will find the Ignition harness, You will need to remove the nylon protective wrap to work with them

 Removing the Lower Steering Column-
 To remove the lower steering column you will need to remove the Tilt lever for the steering wheel. Fold a cloth around the lever, and grab it with a pair of pliers, it should simply pull out of the steering wheel.

Wait to start Feature-
 The wait to start feature for Diesel Engines to allow the glow plugs to warm up and not cause excessive cranking, and possible glow plug relay damage.
 There are two ways to go about a delayed start to allow glow plug warm up.
 First the installer can hook up Remote start to the Wait to start wire. This method is often unused since it is extra work.
 The preferred method is to set a delayed start time through the remote start for example (5 seconds, 10 seconds, 15 seconds, 30 seconds) This is the easiest way to do it, and it gives ample time for the glow plugs to cycle
 Don’t let the preferred method discourage you, If you are worried about it trying to start in the freezing cold with glow plug failure, most units have a built in safety feature for example your truck will only crank for 4 seconds, If there is no start within 4 seconds, It will stop cranking, and try again in 20 seconds, it will crank, If there is no start in another 4 seconds your truck will not Auto start, and your next start attempt will need to be made with the key

 These wire references should be mostly universal through all GM pickup trucks, But you should still double check, A great reference for vehicle wiring diagrams is Bulldog Security that I mentioned in the beginning be sure to double check all of the wires before you splice.

 Aftermarket Alarm Capability
• There are many Remote starts that also come with aftermarket Security System (Including, Sirens, LED warning Bulbs, shock sensors, and knock sensors.
• Most of the Alarm install is very straight forward, If you need help with setting up an aftermarket security system let me know and I will help out

 Technique for taping into a wire
• To tap in to a wire, first you will need to peel back the insulation. To do this take your razor blade and slide it softly along the top of the wire, be sure to always go away from the body. It is always a good idea to uncover about 1 inch of copper wire, to give good working room to connect the wires.
• Once the insulation is peeled back take the point of the razor blade and separate the copper wires in the middle, spread them nice and far apart so there is a lot of space and a big gap in the middle of the wires
• Take the connecting wire from the Remote start, and strip the end of it, be sure to strip off a good 1 inch of the wire, twist the end of the wire and shove it through the receiving wire (i.e. Ignition wire), and wrap it fully around and then Tape it up.
• Many people prefer t-taps, I do not use t-taps I think they are more prone to coming undone

 Hood Pin
• The hood pin is a safety device, which is placed under the hood, when the hood is raised the pin raises and completes a grounded circuit which results in the vehicle shutting down, this is recommended you put in for the safety of any auto shop that may perform work on your vehicle. If at any time there is a complete ground on this wire and circuit the vehicle WILL NOT start
• It is also recommended that you place the sticker you receive with all remote start units under the hood where it is most visable

 Brake Pedal
• The Remote start also has a built in safety feature, where if the key is not in the ignition but the vehicle is running and the brake pedal is pressed it will automatically shut off the vehicle. On the Silverado’s and Sierra’s the brake pedal wire is (White) and is directly above the brake pedal harness, If for any reason there is 12v power showing while the vehicle is running off of the remote start it will kill the vehicle

 Neutral Safety Wire
• This wire must be grounded to complete the circuit and give power to both the bypass module and starter module, If it is not grounded this will result in a no start

• Reasons for not starting (Troubleshooting)
 Neutral Safety Wire is not grounded
 Brake switch is activated and showing 12v Power
 Hood is up, and the hood pin is showing a completed ground
 System is in valet mode
 Bypass or Remote start unit is not programmed right

Tapping into the Factory horn for use with remote start

Factory Horn wire is at the top of the steering wheel in the harness in front of the hazards switch

Tapping into the OBD II port for the Bypass, and Databus Integration
