Correct. My 8V Cali also came without onboard comp in principle, but all the wiring was there up to the yellow plug. I just scavenged a comp and center console button from a german 16V Calibra, changed its chip for a 2.0 SOHC one, kicked off the nasty analog clock, plugged comp, installed & wired button, and job done.

... but i need to find a computer for the engine or find out if it can be reprogrammed... do you have one, and is it usefull?

I have several Opel comps, but unfortunately all their chips are for larger engines than yours. To work in your X16SZ Vectra a specific chip would be needed, which I lack as for now. Any comp, provided the correct chip, would do, so if I ever find a X16SZ chip I'll let you know .

The onboard computer displays instant L/100, average L/100 since last reset, estimated remaining range and average speed. Very useful.
