Comcast Installation Guide

A quick reference for installing Brake Plus into your Comcast vehicles

BEFORE YOU BEGIN....

It is highly recommended that you visit our Installations page with an overview of Brake Plus installations, troubleshooting guide, electrical diagram, full line of installation guides for nearly any passenger vehicle, and more.

the guide page is password protected

To gain access, please contact your Brake Plus representative.

Tools and items you'll need for this installation:

1. A package of Brake Plus bucket modules. These modules have a BLACK stripe across the computer chip that is coated with YELLOW shrink-wrap
2. Silicone sealant
3. Crimpers/wire cutters
4. Pliers
5. Wire strippers
6. Hook tool
7. Blow torch or lighter

Quick Tips:

Module used: BUCKET (YELLOW with BLACK stripe)
The ground wire is WHITE
The POS wire depends on several factors. See more in the full instructions.
We use two different variations of our modules for your Comcast fleet. We have a module specifically for bucket trucks and a “regular” module that works for all other vehicles. They can be distinguished by the shrink wrap on the computer chip, the connectors on the module’s positive wires, and by how they are packaged. A “bucket” modules’ shrink wrap is yellow with a black stripe on it whereas the regular module will be just plain yellow. A bucket module will have blue heat shrink butt connectors on the positive wires whereas a regular module will have red male and female bullet connectors. Bucket truck modules are packaged in pairs with 2 t-taps per bag and regular modules are packaged in 25’s with 25 t-taps per bag.

1. Check Bulbs

Always check that all brake light bulbs are working before starting any Brake Plus install. ALWAYS. This will save you a lot of time and energy down the road.

2. Apply silicone to module

Put a bead of silicone sealant on the teeth of each T-tap and put silicone inside the female spade on both modules. Set aside.

3. Remove brake light lens

Use hook tool to remove the brake light lens from the rubber grommet (the lens may come unplugged from the harness during removal).

4. Locate the plug & remove casing

Locate the plug. Remove the electrical tape or protective casing from the wire harness (3”-4” should be enough).

5. Locate and tap the GROUND (-) wire

Located the WHITE ground (-) wire, and tap it with the included T-tap (to tap, seat the teeth of the T-tap over the WHITE wire and clamp down until you feel a slight "snap/click").

6. Locate, cut, & strip the POSITIVE (+) wire

Locate the positive (+) wire and cut it so you have some room to work on both sides. The positive wire will be YELLOW on the DRIVER's side, and GREEN on the PASSENGER's side. NOTE: If the vehicle has had a lens/harness replacement, the positive wire will most likely be RED. Strip the wire so there is about 3/8" of wire exposed.

7a. Attach the module wires to the POSITIVE (+) wire

Grab the butt connector attached to the YELLOW wire of the module. Seat the crimp-able area of the butt connector in the grooves of the crimper and hold with light pressure. Place over the POSITIVE (+) wire that is going towards the plug/light, and crimp down firmly. Give it a slight tug to verify it is secure.

7b. Attach the module wires to the POSITIVE (+) wire

Grab the butt connector attached to the RED wire of the module. Seat the crimp-able area of the butt connector in the grooves of the crimper and hold with light pressure. Place over the POSITIVE (+) wire that is going towards the battery (or away from the plug/light), and crimp down firmly. Give it a slight tug to verify it is secure.

8. Connect the GROUND (-) T-tap ends

Take the modules black (ground) wire, and plug it into the T-tap connector you previously put on the GROUND (-) wire for the light. Ensure the metal spade is centered inside the cap, and does not go to one side. Press until you feel a slight "snap/click."

9. Weatherproof and secure

With a blow torch or lighter, heat shrink both butt connectors that were crimped on the POSITIVE (+) wire. Zip tie or loop the module around the wire harness.

10. Plug it in

Plug the brake light lens into the harness plug, then insert the lens back into the rubber grommet (be careful not to unplug it).

11. Test and repeat

Test the light, then repeat on the other side.

Tools and items you'll need for this installation:

1. A package of Brake Plus regular modules. The computer chip of these modules is coated with YELLOW shrink-wrap and does NOT have a stripe on them.
2. Crimpers/wire cutters
3. Hook tool
4. Pliers
5. Wire strippers

Quick Tips:

Module used: REGULAR (yellow, NO stripe)
The ground wire is BLACK
The positive wire is LIGHT BLUE
We use two different variations of our modules for your Comcast fleet. We have a module specifically for bucket trucks and a “regular” module that works for all other vehicles. They can be distinguished by the shrink wrap on the computer chip, the connectors on the module’s positive wires, and by how they are packaged. A “regular” modules’ shrink wrap is yellow (no black stripe on it) whereas the bucket module will be yellow with a black stripe. A regular module will have red male and female bullet connectors. Regular modules are packaged in 25’s with 25 t-taps per bag.

1. Check Bulbs

Always check that all brake light bulbs are working before starting any Brake Plus install. ALWAYS. This will save you a lot of time and energy down the road.

2. Open doors & locate panel

Open the back doors of the van and locate the black plastic panel at the top of the door inset (it’s just behind the "U"-shaped anchor the door latches into).

3. Locate and expose wiring harness

Put your fingers into the gap and look/feel for the wire harness that has a black ground wire and light blue positive wire. Pull the wires out a few inches. NOTE: if locating the wire harness with the panel still intact is too difficult, remove the nuts off of the black panel with a socket wrench.

4. Tap the GROUND (-) wire

Seat the t-tap's teeth on the BLACK ground wire and clamp the t-tap shut (you should feel a slight “click”).

5. Cut and strip the POSITIVE (+) wire

Cut the LIGHT BLUE wire. Strip a little of the wire insulation off each side.

6a. Attach the module wires to the POSITIVE (+) wire

Grab the bullet connector attached to the YELLOW wire of the module. Seat the crimp-able area of the bullet connector in the grooves of the crimper and hold with light pressure. Place over the POSITIVE (+) wire that is going towards the plug/light, and crimp down firmly. Give it a slight tug to verify it is secure.

6b. Attach the module wires to the POSITIVE (+) wire

Grab the bullet connector attached to the RED wire of the module. Seat the crimp-able area of the bullet connector in the grooves of the crimper and hold with light pressure. Place over the POSITIVE (+) wire that is going towards the battery (or away from the plug/light), and crimp down firmly. Give it a slight tug to verify it is secure.

7. Connect the GROUND (-) T-tap ends

Take the module's BLACK (ground) wire, and plug it into the T-tap connector you previously put on the GROUND (-) wire for the light. Ensure the metal spade is centered inside the cap, and does not go to one side. Press until you feel a slight "snap/click."

8. Tuck and test

Tuck the wire harness and module back in to the black plastic panel. Test the brake lights to ensure the 3rd brake light is pulsing.

Look for a small bundle of wires that come out of the plastic casing wrapped in electrical wrap. Remove several inches of the electrical wrap to expose the GROUND (-) wire and the POSITIVE (+) wire.

4. Tap the GROUND (-) wire

Seat the T-tap's teeth on the BLACK with WHITE stripe GROUND (-) wire and clamp the T-tap shut (you should feel a slight “click”).

5. Cut and strip the POSITIVE (+) wire

1. Check Bulbs

Always check that all brake light bulbs are working before starting any Brake Plus install. ALWAYS. This will save you a lot of time and energy down the road.

2. Access wires

Open lift gate. Locate a black rubber “boot” on the driver's side, in between the lift gate and body of the vehicle. Remove boot from the port hole in the lift gate. You will find a bundle of wires encased in electrical wrap. Pull the wires out a few inches.

3. Locate and tap GROUND (-) wire

Pull back the electrical wrap to expose the wires. Locate a BLACK ground wire and separate it from the bundle. Locate a BROWN with YELLOW stripe positive wire and separate it from the bundle. T-tap onto the BLACK ground wire with the provided T-tap.
