Magnum Swap, which 02 sensor to use, pre-cat or post-cat

Hey thanks for adding input as I have followed a lot of your stuff! The engine is up and running with just the pre-cat. Smooth as silk!! I owe a TON to this site and a guy here who went OUT OF HIS WAY to coach me through this. I have not driven it yet, but hope that my 97 does not go into limp mode, will find out soon, from what I have read it looks like starting in 98 security features were added so crossing fingers! I can deal with a check engine light for the time being but nice that you shared resource in Florida if I need it!!!!

Another insight I found is that routing the plug wires correctly eliminated an otherwise imperceptible misfire that showed up on a Matco Scanner I was able to borrow to sort my set-up out.

Here's the link to the TSB from Chrysler.
