1.

Set the Radio Select DIP switches according to the radio you are installing.

2. Wire the aftermarket radio harness per the tables to the right and the information

below.  If the aftermarket radio does not require connections for Vehicle Speed

Sense, Parking Brake, or Reverse Signal, proceed to step “3”.

a.

If the vehicle does not use the 28 pin connector (Vehicle Connector 2), proceed

to step “III” below.  There are three different methods for obtaining the analog

navigation outputs from the interface:

I. Vehicles that have the analog signals at the radio: 

Plug the 28 pin con-

nector (Vehicle Connector 2) from the RP4.2-TY11 into the vehicle harness.

Find the Pink (pin 17), Light Green (pin 15) and Purple / White (pin 2) wires

in the RP4.2-TY11 harness and check for wires populating these positions

on the factory side of the connector. If the wires are present, you can use

the analog navigation outputs coming from the Vehicle Connector in the PAC

harness.

II. Vehicles that have CAN data at the radio:

 Plug the 28 pin connector (Vehicle

Connector 2) from the RP4.2-TY11 into the vehicle harness.  Find the White

/ Red (pin 9) and White / Black (pin 10) wires in the RP4.2-TY11 harness and

check for wires populating these positions on the factory side of the connector.

If  the  wires  are  present,  you  can  use  the  “nav  wires”  coming  from  Vehicle

Connector 2 in the PAC harness.

III. Vehicles that do not have the CAN data or the analog wires at the radio:

Connect the long White / Red HS-CAN+ wire to pin 6 and the long White /

Black HS-CAN- wire to pin 14 in the OBDII connector (Fig.1). This will allow for

use of the “nav wires” coming from Interface Connector 4 in the PAC harness.

3.

Wire the Yellow, Red, Black and Blue / White wires from the harness labeled “Connect

to Aftermarket Radio” to the wires on the aftermarket radio harness. The Red / White

wire is optional (see page 7 for further details).

4. Wire the speaker wires from Interface Connector 4 to the speaker wires on the

aftermarket radio harness.  The Blue / White and Brown wires from Interface

Connector 4 will not be needed. Insulate the unused wires and ignore the remaining

Brown Loop (not needed).

5. Depending on the aftermarket radio, either the Blue / Yellow wire 

or

 the 3.5 mm

Jack (not both) SWC Outputs will be used.
