1992 galant

i have a 92 galant with the sohc and i got the dohc motor and ecu for the 90 eclispe motor. i got the wiring harness from the 90 eclispe as well. they only problem i got is the wiring harness is from the motor to bulk head. is there any way to splice in my harness or do i have to get a complete wiring harness to that enginge. plz help .im so lost with the wiring harness.lol

are the motors both 2.0?

yes. im going from 2.0 sohc to 2.0 dohc.

so then why not swap the heads and save the trouble of major wiring. alot of us 7g guys do that with the 4g63 heads (95-99 turbo eclipse) on the 4g64 block

because i spun the rod bearin in the sohc block and it had 215 thoushand miles and the igintion is diffenernet
