On my jumper harness there was no wire in the d4 slot. I took a 5 inch peice of wire and incerted it into the plug (that plugs into the ecu). I left this wire there for for futute cel checking. Then, I took a 2 foot peice of wire and attached one end to one of the bolt that hold down the passanger seat. I dove my car until the cel came on and I touched both ends of the wires togather and the cel started blinking. Let me know if you need any help.
