I have a Canadian model 90 CRX si with a pm6 ecu and a DOHC ZC swap. I just bought a used pg7 ecu and I thought I could just plug it in to my existing harness and go. Apparently not. When I try to start the car it just rolls over like its not even sparking. Do I have to make changes to get this ecu to work?
 
the PG7 from the 88-89 Integra will work - 86-87 Integra will not work - see pictures below - 88-89 on left - 86-87 on right

the number on the 88-89 ECU should be 37820-PG7-A0# - on the 86-87, it is 37820-PG7-A66 (these are for manual transmission)
