CRX SI Heater/Blower in a Civic HB DX with CRX Dash

Ive got the heater controls/motor/blower the whole deal from a 1989 CRX SI.....Has anyone ever swapped this into a 1989 Civic HB DX Model with CRX Dash. I know the motor and everything will bolt in, but the problem I encounter is within the wiring. Is there a way to modify the Main Civic Harness to accept the CRX's electronically controled Heater System.

Any Help is appreciated.

Thanks

Brad
