Anyone know what these 2 plugs route to? The 5 wire and the 2 wire?With the info given above Im sure its all smog related but thats a lot of wires for just the smog system. I want to make sure I dont unplug something needed.
This is the only diagram I chould find, It only shows the 5 wire connector? Im not sure on the 2 wire connector.....Its been 6 year since i ripped all this stuff off mine. What colors are the 2 wires?
