1969 Chevelle Wired with Infinitybox

Here’s another great customer car wired with our Infinitybox system.  Matthew W sent us these pictures of his finished 1969 Chevelle.  He’s had this 1969 Chevelle a long time.  This is the first car that he ever got to change a tire on.

He has a 383 stroker engine in it with Aluminum heads.  It is fed through an Edelbrock dual quad carb set up.  He has an MSD ignition box giving it spark.  He has the Vintage Air Front Runner system with their Gen-IV system.

He wired the car with our Infinitybox 20-Circuit Kit.  He added inLINK for security features.  He also add inRESERVE to manage his trunk-mounted battery.

You can see this picture of his rear POWERCELL and the inRESERVE solenoid protecting his battery.  The rear POWERCELL is mounted conveniently in the rear, right corner of the car.  This is very accessible if he needs to change a blown fuse, the runs of wire are short and it can be hidden neatly behind the custom trim piece that he made.


Congratulations to Matthew for finishing his car.  It is spectacular and we are proud to be a part of his build.

If you buy inLINK with your 20-Circuit Kit, we pre-install it for you at the factory.  If you don’t buy inLINK up front, you can add it at any time.  Installing it to your MASTERCELL is very simple.  You only need a screw driver.  No software updates are needed.  The MASTERCELL is pre-programmed to talk to the inLINK radio receiver board.

The inLINK kit includes the inLINK Radio Receiver Board, two spacers, two screws and two of the inLINK key fobs.  The following instructions show you how to install the inLINK Radio Receiver Board into the MASTERCELL.

STEP 1- Disconnect the MASTERCELL.

Remove Back Cover

Once the screws are removed, carefully separate the plastic housing (A) from the back cover (B) as shown in Figure 3.  Carefully separate the housing and back cover of the MASTERCELL unit by first turning the unit upside down and gently placing your fingers in the input connector shells.  Gently press up on the connector pins while holding the plastic housing (A) with your thumbs until the back cover is separated from the housing.  Be sure to keep the plastic housing facing down to keep the buttons in place. If they do fall out, locate all five buttons and put them to the side.  Set aside the plastic housing, keeping it upside-down so that the buttons do not fall out.

STEP 4- Prepare the inLINK Radio Receiver Board.

Our inLINK Wireless Control Accessory is our most popular add-on to our 20-Circuit Kit.  It gets you powerful control of your car’s electrical features through a simple 4-button key fob.  The inLINK accessory comes with a small radio receiver that gets installed inside your MASTERCELL.  There is no external box that you need to make inLINK work.  We recently published this video that shows you the details of inLINK and what it can do for your car or truck wired with our Infinitybox system.  Check it out here.

We received a great question from a potential customer. He was looking to add the Infinitybox inLINK wireless upgrade to his system and wanted to know how secure it was.

inLINK is a great option for your Infinitybox kit because it easily adds remote control to your wiring system. You get our inLINK radio module and two key fobs. The radio module easily installs in the MASTERCELL.  If you purchase inLINK with your kit, we pre-install it for you. If you purchase it later, it is very easy to install yourself. It is completely plug & play with no software required.  This link shows you how to install the inLINK radio module into your MASTERCELL.

You can use your Infinitybox inLINK key fobs to control many things including your lighting, popping your doors and expressing-down your windows.  Most importantly, inLINK gets you security and alarm functions. When you press the lock button on the inLINK key fob, Infinitybox completely disables the inputs for the ignition, starter and fuel pump. This is done from within the MASTERCELL so it is very secure. If you try to start the car when Infinitybox security is on, you get a clear message on the inSIGHT LCD module alerting you that the car cannot be started. Additionally, you can tie MASTERCELL inputs to switches in your car so that if they are triggered when security is on, you can sound the horn or an external siren. This makes inLINK a very powerful vehicle immobilizer and alarm that is built right into Infinitybox with no additional wiring required.

Since inLINK is the key to the vehicle’s security, the question about the wireless encryption is important. We use Microchip’s KEELOQ hardware and encryption technology for inLINK. This is the exact same technology used in OEM remote entry systems, vehicle alarms, highway toll collection, garage door openers and medical device monitoring.

KEELOQ uses a frequency hopping, 64-bit code system. There are over 4-billion code combinations and every time you press a button, the system randomly generates a new code. The hardware is designed never to react to the same code twice. If you could try each of the different code combinations, it would take you 17-years to go through all of them.

We have our own seed key that is unique to Infinitybox so that other devices using the same KEELOQ technology cannot link to our system.

The Infinitybox inLINK system uses an industry proven, rock-solid technology to ensure reliable transmissions and hack-proof security.

Training inLINK


inLINK is one of our most popular accessories for our 10 and 20-Circuit Harness Kits.  It gets you a very easy way to add an alarm, security and a vehicle immobilizer to your car.  You can either purchase inLINK with your kit up front or you can add at any time down the road.  If you add it down the road, you are going to have to follow these instructions for training inLINK.  This is a simple process that pairs the remote key fob to the radio in the MASTERCELL.

We use a secure and encrypted system to protect the communication between the key fob and the MASTERCELL.  It uses a 64-bit, rolling code encryption scheme.  That means that every time you press a button on the fob, it changes the secret password.  There are billions of combinations of passwords that make hacking into the transmission practically impossible.

Each of the key fobs included with the inLINK kit has to be trained to the MASTERCELL.  If you order inLINK with your 10 or 20-Circuit Harness Kit, we pre-install it and train it for you.  If you order this separately, you need to install the radio board and train the key fobs.

This link will show you how to install the inLINK radio board in your MASTERCELL.

Here are the steps to train your key fobs to your MASTERCELL.

  1. Remove the cover on the MASTERCELL.
  2. Press and release the “TRAIN” button on the MASTERCELL.  You will get a message that will read “To Learn… press any button 2 times”.
  3. Press the lock button on the key fob once, wait one second and press the lock button on the key fob again.  After a few seconds, you will get a message on the screen that reads “Learn Command Accepted”.  You may also get a message that reads “Existing Transmitter Overwritten”.  In either case, the MASTERCELL and key fob are paired.
  4. Repeat this process for the second key fob.
