i need to replace both my post cat converter o2 sensors on my b5 a4 2.8l. i havent been able to find any clear diy i can get to the o2 no problem but how do guide the cable to where the plug in and where exactly is it. thanks

 

the same way the original ones were guided. they just clip in up by the firewall. but they don't have to be guided the same exact way. just make sure they are out of the way of anything hot or movable.
