Seat Leon Mk1 1.6 16v 105hp , AZD engine code , need help with cruise control!

[Kalomax]

Hello, I tried to install cruise control on my private car. But during the installation, it turned out that in the front under the wipers, from the socket (to which the cruise control cables are connected) to the car's computer, several cables are missing, which are not there at the factory. I have passed the cables from the lever to the sockets and my question is, could you release these missing cables that go into the car computer
