Hi I’m rebuilding the front end of a 2018 Seat Leon Cupra and I’ve got to the point of connecting the Drivers Assist Radar Module but the issue I have is the the 8 pin connector has been ripped off and not with the car. I have a replacement 8 pin connector and a wire with seven different coloured wires. Where can I find a wiring diagram for what colour wire goes to which numbered pin.

Pin 1: Brown (Earth)
Pin 2: Orange/Gray (CAN high - goes to engine cmpt. wiring harness, then pin 12 of the 17-pin white connector on left A-pillar, then main wiring harness)
Pin 3: Orange/Brown (CAN low - goes to engine cmpt. wiring harness, then pin 13 of the 17-pin white connector on left A-pillar, then main wiring harness)
Pin 5: Orange/White (CAN high - goes to pin 9 of the 17-pin brown connector on left A-pillar, then pin 2 of the 12-pin connector of the driver assist camera
Pin 6: Orange/Brown (CAN low - goes to pin 11 of the 17-pin brown connector on left A-pillar, then pin 1 of the 12-pin connector of the driver assist camera
Pin 8: Black/Green (10A fuse at SC32)
It should be noted that the wiring diagram shows two orange/brown wires, maybe because they are both shown as CAN low but I find that curious anyway.
I recommend you to compare actual wire colors in your car, because sometimes they might be different than what the diagram shows.
Thankyou I will have a look and try this think I may have 7 wires

Canbus consists of twisted pairs
Every pair has an orange/brown for can low
Can high changes depending on the bus
For example
Comfort/convenience
orange/brown
orange/green
Extended can
orange/brown
orange/grey
Infotainment
orange/brown
orange/violet
Private can between radar & camera
Orange/brown
orange/white
Thank you very much for the explanation.
Having two orange/brown wires without a connector at the radar side won't make the original poster's job easier though. He would have to track them down to see where they lead, or maybe better, make a measurement using the camera side orange/brown one.

OK, now I get that, thanks again.
@Stuart 51
The pair with orange/brown and orange/grey wires will go to pin 3 & 2, respectively.
And the other pair with orange/brown and orange/white will go to pin 6 & 5, respectively again.
