Default 3800 Plug Wire Routing

Hi all. Recently did my LIM and UIM thanks to a lot of the advice here and it seems I pulled it off! However, lately I've been getting a P0306. I read about keeping the #6 plug wire away from the O2 sensor, and the morning that I moved the wire away from the sensor, the CEL turned off on its own and is now just pending (to hopefully fully go away as I drive more). However, my question is, does anyone have good picutres of how the plug wires should be routed on my 3800 series 2 (1998 Buck LeSabre Custom). Right now they're just incorrectly kind of laying in there. Also, there are two plastic plug wire clips that were on the engine as well and I have no idea where they go (PO took the plug wires off; never took pictures). Any help would be appreciated. Thanks again all!

You can run them any way you want, just keep them away from hot things and other wires.

Especially that O2 sensor wire. The PCM needs to see millivolts coming from it. With a bad spark plug wire sitting on it, the voltages can spike.

Thanks guys. Yeah I think my misfire problem was a combination of the cheapo plug wires the PO put in there and the #6 wire rubbing on top of the O2 sensor. No more codes so far; keeping my fingers crossed.
