OK guys need some help, I've followed the Lt1 swap guide for removing what's not needed. My butchered oe harness was missing o2 connectors but I've figured that out I think. Have a group of wires coming out at the rear of the intake right side (see pic) don't know what they are to?. Also I don't have a obd2 port and are these 2 for something. Thx guys all advice and help is appreciated.
