you need the primary before the cat...the one in your cat is the secondary and is no longer being used since obd1 doesn't look for it. you'll need to add an o2 bung in the end of your header of just before the cat somewhere.

i tried calling you back...sorry it took so long. i assume this is the question you were trying to get a hold of me for. in the future feel free to ask your question on my voice mail if i'm unable to answer. i'll be more than happy to call you back w/ a message and if i don't get you i'll leave a message with the answer.
