one more time about trailer ABS warning light

There are 4 ways to actuate TABS warning light.

1. European way - to use one more connector for ABS power supply. Pin #5 is used for ABS WL
2. To use power supply of TABS via trailer light connector, pin #7. No WL in truck, warning lamp is mounted on trailer to be seen in rear view mirror. Was used for old trucktors.
3. To use pn #3 of additional N connector.
4. To use PLC J650 via PN#7 of N connector

All these ways are legal, but freightliner used to install different wiring for different markets, for example here they fit trailer rear fog lamps and trailer reverce lamps, so N connector got more pins used.

Okey i had a chance to hook up to my buddy's new trailer and it looks like the trailer abs light is actually caused by a truck. Any ideas where to look first? Could it be fuse/ relay or bad wiring?

Hello I have a 1999 western star and a 1998 tremcar tanker and the driver side front axel on the trailer locks up if I have to brake hard.when I apply the brakes the abs light on the trailer comes on and goes off when I release the brakes. I have replaced the module and sensors and the tires still lock up.dot in Texas wrote a ticket for the light staying on. I have had the truck in the shop for 5 weeks and paid over 4000$ and it’s still doing the same thing! any ideas?
