i just swapped in a 1996 b18b1 into my 1999 honda civic ex. i had to get a si engine wiring harness in order to hook up the Dizzy. ive been running a 1.6 sohc ECU because the LS ECU i got was OBD2a and wouldnt plug in. now i just got my OBD2b LS ECU and went to plug it in and now my car wont start at all. it will start with the 1.6 ecu but not the 1.8, im so confused on what the problem is.

here is my set up.
1996 LS motor/ tranny (i used a si wiring harness to run the car)
1997 GSR dizzy
00-01 ls ecu
SI axels


the only thing i can think of that would be the problem is the GSR dizzy has 9 wires coming out of it and going into a plug. now the SI wiring harness has 8 wires going into a plug. they plug in perfect but im thinkin my car wont start because of this 9th wire not connected. its a thick solid light blue wire.

Does anyone have any input into what the problem can be??? like i said my car will run on a 1.6 ex ecu but not the 1.8 ls ecu. any and all help is wanted. thanks
