hooking back up pulse air...yea....i know

i'm trying to bring the emissions back to stock on my 89 yj 4.2l S Islander and was wondering if anyone out there was crazy enough as me to have done this or still have the original pulse air system on their 4.2l jeep. If so, I am in need of some visual help. None of the diagrams i have found show good detail of how the hoses are routed out of the back of the air cleaner assembly, under the engine, back to the cat and back. Please post pics of how this should look so i can complete my set up. thanks for any help. no i don't want to nutter. I've already gone too far down the rabbit hole. eventually i'll do the mopar performance upgrade but for now just need this beast to pass inspection.
