2.4 Data Wires

Run two new wires (24 AWG minimum) from the headunit to the trunk. I did this by running a

CAT-5 ethernet cable. This type of cable has 4 pairs of wires. Each pair contains a solid and a striped

colored wire that are twisted around each other a few times an inch. This twist is also a standard of

the CAN network. Even though only one pair is needed for this installation, it is easy to run the whole

CAT-5 cable. This will result in three extra pairs in the cable already run that may or may not be used

for future projects. I chose to use the solid wire for CAN L and the striped wire for CAN H. This wire

installation will require the removal of some door sill trims to tuck the wire away out of sight.

Behind the headunit, splice the solid wire into the CAN L wire from Pin D10 of the RNS-E and

splice the striped wire into the CAN H wire from Pin D9 of the RNS-E in the PNP harness.

At the trunk end of the wires, connect new wire terminals and plug the CAN L wire into pin 1 of

SAT connector T8s, and the CAN H wire into pin 2 of T8s.

In the past I have used non-twisted wire pairs for my CANbus network with no problems.

In the picture below the orange twisted pair is used to connect to my small T8s connector on the tuner

(after passing through the large white connector in the harness). The other twisted pairs are just

pushed back out of the way and will sit dormant until used on future projects.
