No actually I meant the pinout of ch341a and the one of the T48 (the chip on the mobo is a standard one)
I am sure it is and if so, I can use the attached scheme.
From your diagram it looks like there's a 25 series 128Mbit chip on your board, so took a screenshot from some random ditto in XGPro:
There are some signal name variations between the diagrams:
SI = DI
SO = DO
SCK = CLK
You got the mobo header pinout in your diagram, and the T48 ICSP port in mine. I don't really get exactly what you want to do, but I'd just wire it up with individual Dupont wires according to the two diagrams. The extra ground wires along the clock wire shouldn't be necessary, they're just there to reduce crosstalk etc. If there are any problems, try adding them or lower the SPI clock frequency.
Edit: or is that MSI cable perhaps connected to the ZIF socket rather than the ICSP header in the programmer end? In that case, the cable/diagram would work if the T48 and CH341A uses the same connections for their DIP to SOIC8 adapters. I'd still not take any chances though, easier to just wire it up with Dupont wires than verifying that the connections with the cable are correct.
