I'm trying to see all the emissions parts I need and where they are located in the engine bay. I understand the air pump but want to see where they go and etc. Anyone with diagrams or engine bay pics would be great with emissions equipment would be very helpful.

techlaf, Good God man! I thought I was the only person running emissions stuff. That looks mostly like the wife's '76, although she has an aftermarket cleaner on it. Congratulations for keeping that '75 in stock trim. There are enough modified early Broncos to go around.

Sometimes I feel like I'm looking at spaghetti, but I guess its doing its thing and it runs like a top most of the time. What's funny is the two times I've brought my truck to a show or gathering, the biggest compliment I get is on all the stock smog stuff. Who woulda thunk that would be rare, but I guess it is.
