SOURCE: System Remote Control Wire.

Wal Mart generally has 4g wiring kits for ~$40. Some of the kits contain everything you'll need to install your amp (including RCA cables, fuses and fuse holders).

If you want to understand more about car audio installation, read through the following site:

SOURCE: RS-422 connection RJ12

What I was told through the mfg. was:
pins 1,8 =NC
pins 2,7= Chassis Ground
Pin 3= TX-
Pin 4= TX+
Pin 5= RX-
Pin 6= RX+

This would actually be a RJ45 (8pin) but uses the 6 pin cable and only 4 com wires.
Evidentally there is no standard for the pin usages for serial communications with RJ connectors. So this information might not be valid for other equipment.

Hello everroth,

You can download a copy of the manual from Sony here. It's only a 2 page PDF document and figure 3 shows the wiring color codes and wiring diagram.

Hope this helps.

Is the HD CCTV camera analog compatible? I would imagine not if it says HD in it's name. But you can try using a converter box with it because if the camera is outputting HD you need to convert it to analog which the TV can understand.

Does it supports any brand of cctv cameras or will there be any incompatibility with same brand..


It support all brand of CCTV.
for PTZ CCTV, It has to have the Pelco protocol so the WJ-HD716 can control the camera.
in that case, the connection will use the RS485.
