Installation Procedures
STEP 1 – Antenna Installation
FFrroomm OOUUTTSSIIDDEE tthhee uunniitt::
1. Chose one of the two curbside antenna locations as shown ((FFiigguurree 11)) to help avoid potential
interferences inside the unit, e.g., harnesses, devices, etc.
• Confirm entire antenna base will be properly supported BEFORE drilling antenna hole.
• Confirm there are no obstructions inside the unit BEFORE drilling antenna hole.
2. Mark antenna mounting hole location.
a. Drill ¾” hole.
b. De-burr hole and thoroughly clean area where antenna will be mounted.
3. Remove hardware from threaded antenna base.
4. Route antenna cable down through mounting hole.
5. Remove paper liner from antenna base.
NNoottee:: Adhering the antenna helps facilitate single-person installation.
a. Orient antenna with tall portion nearest the bend whether above or below the bend.
b. Set antenna in position and press firmly in place.

FFrroomm IINNSSIIDDEE tthhee uunniitt::
6. Remove just enough foam to prevent any from being trapped under the antenna hardware
that could affect the joint.
7. Reinstall antenna hardware onto threaded base.
a. Tighten antenna nut to 53–62 in–lb (6–7 Nm).
IImmppoorrttaanntt:: DO NOT over tighten the nut or damage to the antenna will result.

STEP 3 – Communication Harness Installation
NNoottee:: Refer to Figure 5 – Communication Harness Connections on page 6.
1. Attach 35-pin connector from communication harness to BlueBox module.
2. Locate CCAANN 00 4-pin connector ((PP22)) and CCAANN 11 4-pin connector ((PP33)) adjacent to the
IntelligAire III controller ((FFiigguurree 44)).

Blue Arrow = CAN 0 (4-pin connector P2) Yellow Arrow = CAN 1 (4-pin connector P3)
3. Remove ((CCAANN 00)) harness connector (and jumper segment if resistor is present) from PP22.
NNoottee:: The communication harness supplied in the kit has two connectors bundled together
with a BBlluuee band wrap and two connectors bundled together with GGrreeeenn and YYeellllooww
band wraps. Be sure to make the correct connections in the following steps.
NNoottee:: Numbers in parentheses refer to harness components in Fig. 5.
a. Insert male connector from BBlluuee side of communication harness (2) into PP22.
b. Insert female connector from BBlluuee side of communication harness (3) into the harness
connector removed earlier.
IMPORTANT!
CAN Communication Procedures must be completed before continuing.
See page 7
4. Remove ((CCAANN 11)) harness connector from PP33.
a. Insert male connector from YYeellllooww//GGrreeeenn side of communication harness (5) into PP33.
b. Insert female connector from YYeellllooww//GGrreeeenn side of communication harness (4) into the
harness connector removed earlier.
5. Secure all harness adequately with band wraps.

STEP 4 - CAN Communication Procedures
Resistors are required at each end of the CAN network to prevent signal reflections. Two
resistors in entire harness will measure 60 ohms (two 120 ohm resistors, in parallel).
IImmppoorrttaanntt:: The following procedure must be followed to ensure the CAN communications work
properly.
1. With the power off, measure the resistance between CCAANN HHii and CCAANN LLooww (terminals 2 and
3) on the CAN_0, P2 connection.
a. You should have a measurement of between 60-120 ohms.
b. If you do not have a measurement between 60-120 ohms, communications may work
temporarily but will be unreliable and eventually fail. Continue to Step 2.
2. Check for correct value CAN termination resistance in the harness. Refer to your unit wiring
schematic for location of factory installed CAN resistors.
a. Add or remove termination resistance as necessary.
b. Repeat Step 1 above and confirm measurement is between 60-120 ohms.
3. Return to page 4, step 5.
