S52B32US post-cat O2 sensor connections to wiring harness

[dynagroove]

Hi all, this is a follow on to my previous thread concerning exhaust and O2 sensors for an OBDII S52 swapped ti. So the new custom exhaust is installed and it sounds and looks great. I purchased 4 new O2 sensors for the car and set out to install them today. However, I cannot locate the post-cat sensor connections at all. I spent a good hour pouring over and under the car looking for these connectors. I'm assuming they should be 2 wire bundles with 4 wires in each. I understand that they should be on the driver's side around the transmission tunnel.

I'm also going to assume that whoever did the swap either cut and taped these connections very short, or they didn't even install that part of the harness (if that's possible). This is due to the fact that emissions are not required where I purchased the car.

Can anyone assist me in locating were on the wiring harness these 8 wires should feed into the main harness? Any help is appreciated.

Thanks,
Jeff H.
