DX to SI Swap. Need Help Wiring

I have the SI harness for the engine bay but not in the dash. I have the si ECU in and plugged into the DX harness in the dash then the Si harness in the engine bay but one of the plugs dont match up between the SI and DX harnesses. in the back of the engine bay infront of the driver. any links or help is appreciated.

you've got to either get the inside part of the harness or add wires to it. Mainly because of the differnt distributor and mpfi

where do i add the wires and where do they goto??
any links or help please
