Shift light signal wire?

[CTC]

I saw in other post that the shift light signal (green) wire should be connected to the pin 48 in ECU, the white wire with black stripe. But I think that can be connected to the same wire rear the OEM rev metter. I removed the gauges and found 2 wire bunch, the problem is that I found in it two white wires with black stripe. What is the correct one? Can I connect it there? or better if I connect it to the ECU?

I cut the two wires and try it with both, the correct was the second, The shift light work correctly now
