A crimping tool: Yato YT-2255

Let's build a wiring harness that will look like this:

• Connector for the wheel angle sensor of your choice take a look around at this shop

Wire

Above cable uses YSLY-JZ cable that is heat and oil resistant We'll need:

• 3 wire that is 6meters for the Wheel angle sensor (0.5mm2 is fine that's 20AWG)
• 2-5 wire that is 2 meters for the push button and some spare for hydraulic lift, work switch, etc (0.5mm2 / 20AWG)
• 2 wire that is 3,5meters for the motor (0.75 - 1mm2 that's 19-18AWG)
• 2 wire that is 1+ meters for the main power input (same as above)
• 3 wire that is 2 meters for the main switch (same as above)

Please note that Hydraulic steering will require extra wires: Lock pin 2 wires + pressure sensor 2 wires + maybe dedicated 12V for the automotive relay.

Assembly

Crimp and assemble according to the Pinout

AMPSEAL 23

Here's the official video and here's some step by step video Things to watch out for:

• The crimped area can't be bigger than the connector itself as it has to go quite deep (try to get a quality crimper choose the head accordingly)
• It has to click when pushed in and from the front it has to be almost flush
• You can disassemble it if that makes it easier

Main switch

pin1	pin2
ground	ground
NC	NC
NC	12V In
Backlight	12V Out

Push button

The middle and one of the outer wires can act as either an NO / NC. Choose the one that connects the wires when pressed. 1 goes steerpin 1 goes ground.

Validation

Add 12V power to the wiring harness Turn on the main switch -> does the logo light up?

Connect your sensors, etc and test it in your desk with a spare board
