Auto wiper/lights retro fit help

[Stephen555]

I have got together the auto light switch and rain/ light sensor to fit to my Audi TT mk3 roadster 2017 , I’m confused to wiring snd would anyone know the wiring code for this install
Three wires
Ground , live , and third wire to ??? This is as far as I got as I didn’t get wiring code with the loom I received . I believe live is to fuse box on passenger side possible fuse 8. The other is ground. And the third I’m lost on .
many help here much appreciated

Not something I’ve any knowledge of I’m afraid. Where did you get the loom from?

Aliexpress
it came with the R/L sensor It’s identical to all the others available online .
I figure it out as cpl of wiring diagrams about but mostly for the A5s . Up to now I have installed CarPlay , the Sat nav , reverse camera, puddle lights with Audi rings and red door lights. Just waiting on new locking mech for ABS and finish off the auto hold . I might consider doing parking sensors at some point but holding off till all these other retrofits are completed . It’s all a learning curve and don’t mind updating when it’s all done to help others out

You might want to have a look at Erwin if you’re not already aware of it. It’s Audis online workshop information service. You can pay 5 euro for an hours access with the ability to print off as much as you like. You should find the wiring diagrams you need on there if you still need help with that or anything else you’re planning.

You just sign up for free and then after you log in and select the car, you can choose your subscription rate.
