im not too familiar with the del sol but
1.if the wire harness is a too part design like obd1 cars then u have to use a integra or obd1 civic wire harness depending on the year of your car..
2.i dont kno if the mounts will drop directly
3.if the wire harness is a one piece design like the 96-00 civic then u will have to find a 96-98 ex harness and an obd2a Ecu
like i said im not too familiar with the del sol but good luck hope this helps u
