    Lenovo T14 - Reading MEC Chip

    I have a Lenovo T14 I need to remove Bios password.

    I have the RT809H Programmer, i connected wires to JTAG but cannot read chip (MEC-1663).

    Iv attached diagram of how its wired up.
    I used diagram from another T14 model but the board is slightly different i cant find a diagram for my exact board.

    Did i wire this right?
    Does CLK go to TCK jtag point?
    Someone said I need 10K pull up resistor, what points do i connect that to?
    I don't see the missing resistor other point to my boards a bit different.

    I know you cant edit out the password but if you re-flash the dump it clears iv been told. (rt809h + read MEC1663 + write MEC1663) then you use the maintenance tool to restore serial etc.
