The manual plug has 8 pins the auto 10 pins.

the only thing i know is to splice the wires, just don't know what to do with the xtra 2 wires.

has anybody done this and can lead me in the right direction
You will have to change a lot more than the control panel.
Like the hole heater and ac unit and maybe the hole PCM/VCM and all wiring.
