What happened to the wire harness from the 90? Why did you not used that. Not too much diff. from the two, something is crossed, does the 90 have air bags? Check your wire diagram some one like egalemotorssports, may have one scanned as a picture he can post for you. Or get a Hayes book that shows connections. Sounds like the always on hot lead is connected wrong fuel should turn off when key is off. Start their first. then move on. Do you have a voltage meter, check the wires key/on -key off.
