3. Setting the Jumpers
The Jumpers are on the PCB inside the interface box. By default they are set up to suit most vehicles and should
usually only need to be changed if fitting an Alpine head unit. The jumpers are set by moving them between
positions 1 and 2 or positions 2 and 3.

Position 2-3

J2

J3

4. The Reverse and Speed Pulse cables.
The reverse output (blue wire) is only needed when fitting a reverse camera to the new head unit. The grey speed
pulse wire is needed when fitting head units with built in satellite navigation and some Kenwoods. If not required
these can be insulated and ignored.
5. The speaker adapter (brown ISO connectors)
If you are not getting phone or navigation audio through the front speakers, add this extra cable to swap the audio
output from back to front. This is most often required on cars with original Boston Audio system.
Make sure the patch lead is connected to the 4 pin plug on the interface and the input on the new head unit.

Connect the two wires (BLACK AND PURPLE) or the 3.5mm jack to the steering wheel control
inputs on the head unit. If head unit uses 2 wire system then connect to SWC1 and SWC Ground
or KEY1 and KEY Ground wires. The steering wheel controls will need to be programmed into
the head unit after setting the number of flashes. See overleaf.
