air tubes
Due to emissions I had to replace the cats on my '86 Bronco. I took a y-pipe from an '88. Can anyone tell me where the air tube connects to? I can't see anything disconnected on my bronco behind the air pump.
THANKS!

Air from air pump goes through some valves and t's.
There is a pipe connecting to the rear of the heads.
There is also a pipe leading to the cats.
On the factory setup ('86 302) the the pipe connects to the exhaust between the two cats.
The added air helps the second cat, but hurts the first cat. Aftermarket cats designed for air injection should have a connection on the cat for the pipe.
