Ok I Have Everything I Need To Get The Motor In The Car. Mounts, Linkage Is Getting Cut And Welded, Axles,ect. What Im Having A Problem With Is There Is A Green Sensor On The Back Of The Motor By The Coolant Fan Switch And Oil Sending Unit That I Dont Have A Plug For On The Harness. EVERY Other Plug Is There Except This One. Right By It Though Is A Plug That Went The Intake Of The D16 That Was In The Car, So Do I Just Splice Into That Or Do I Need To Use The Teg Harness. Also I Was Told I Could Use The Stock Si Ecu From The 89 Civic On The Motor, Is This True Or Do I Need Another? ITS A PM6
 
i would use the stock ecu, general rule, head, dizzy, and injectors should be all same and that should be the ecu u use, the clip you cut off the integra harness and slice it correctly to the stock harness.
