3.Remove the ALTC wire from the ECU connector (OBDI A16, OBDII-A A19, OBDII-B C2). Insert the Coil Pack Retrofit SYNC wire (white/brown or purple) into the connector cavity in the same place.
4.Solder the Coil Pack Retrofit power (OBDI A25, OBDII-A A11, OBDII-B B1) and ground (OBDI A23, OBDII-A A10, OBDII-B B2) wires into the ECU power supply close to the ECU connectors. Use soldered connections - do not use 'T taps' or crimps.  Do not wire the Coil Pack Retrofit ground wire to the chassis or ECU case.
