Its a transverse engine. The first 3 plugs (plug 2, plug 4, plug 6) are located in the front facing the fans. The other 3 are a bit tricky. You have to reach behind the engine near the firewall. This is where plugs (plug 1, plug 3, plug 5) are located. PLug one (plug 1) is tucked on the far left side (follow the wire) and the other 2 (plug 3,plug 5) are side-by-side on the right side. You need to use a swivel piece socket attachment to get in between and screw out the plugs. Its hard to see the plugs so you'll search for a while. Use the help of a mirror and light to see the exact location. Once you got the area figured out then you can feel your way through and use the tools.
