I have a 1989 Camaro and I put a tpi harness in and it doesn't have the power block by headlights it has to wires with what looks like a male and female oxygen sensor plug red and orange the harness doesn't have the plugin for the electric fan am I suppose to use the plug from the old harness to fan? I don't know where the fan go threw the old harness and I have no idea what the orange and red wires are for besides I'm thinkin the power block it also don't have the power steering pressure plug the sensor on the power steering line do I even need that plug what does that sensor do ( I do not know what year the harness is for but it's brand new never installed and only numbers I can find on it is 3226) any help would be greatly appreciated
