I´ll answer myself
I soldered 2 cabels from ecu to motronic unused pins and the problem should be solved, I´ll connect it tomorrow, then I´ll see does it also work
I used P259 outputs 6 and 7 (EC36 pin 30 and 31) and connected them on motronic pin5 and pin7 what are not used anymore, cut the cables from the loom and I have two extra outputs
EDIT: It woks
also I discovered that from vems there already are some outputs what I was not awear of, not documented, on of them on motronic pin 22 (check engine light), and onother on SSC6 plug on pin1 what was supposed to be input.... wery strange...
