Yes(the wiring on the passenger side of the vehicle from the firewall)-this was on a 90 BII, and don't remove anymore wiring than you need to from the BII. It will complicate things for you-you can always start pulling later if you need. People start cutting wires that never needed it and have more issues reconnecting. Some 2.9 computers will run the 4.0-check the numbers on them. They have the exact same factory numbers.
