I have found a way to program those annoying IR remotes .
Itwas indeed two loose connectors in the dash, then putting the key in the contact and turning to ON. using every remote several times, then starting the engine, take out the key and disconnecting the wires again.
i will be posting some pictures of my yellow SVX lsi in some time...they've told me it's a really rare colour..

merry christmas to everybody!!!
