GRA for SEAT Leon: Explained & Benefits

Hello,

I've already read a lot about retrofitting a cruise control (GRA) system in VW/Audi vehicles.
I have the following problem.
I have a Seat Leon, model 2002, with a 110hp TDI engine (not a PD engine). I have a turn signal lever with a GRA (Gear Range Indicator) function, but I can't find the end of the wiring harness anywhere in the footwell or behind the relays where the cable from the turn signal lever should be connected.

Does anyone have any idea where I can find this (and actually be able to find it)?

I am grateful for any advice!

Regards,

silverleon

Hi,

I have no idea about the LEON, but for the TOLEDO, the wiring harness needs to be connected to the engine control unit (ECU). Otherwise, it shouldn't be much different from the conversion on a Golf 4.

I installed the GRA (automatic rear wiper) myself in my Leon, and it's the same as the one in the Golf or A3. You need to run a cable from the lever to the black 10-pin connector located behind the relays. (There are also a white and a red connector next to it).

Hi,
sehr guter TIP! Thank you!
I found the black 10-pin connector, and the side facing the engine control unit already has all the necessary connections.
Exactly the same color codes in the same positions as in the GOLF 4.
Under http://www.jagiella.net/dirk/auto.htm is the appropriate electrical plan.
Therefore, I only need to get the connectors now, and then I can start.

Thank you and greetings.
