I'm looking around the truck trying to find any anomalies and I find this in the engine bay. It is sitting on the back of the intake and a wire is running down the back of the firewall toward the transmission. Any ideas?
It looks to have two vacuum ports on it, one at one end and one at the other.
That may have been the actuator for the flap in the snorkel of the air filter to let heated air from the exhaust manifold during warm up or allow vacuum to the distributor .

Has nothing to do with the air cleaner.
Geez Louise! OP failed to mention one word of what the hell he's working on, but the part in the pics is a 12A170 "distributor modulator valve."
There are two types: D2AZ-12A170-B & D2SZ-12A170-A as it depends on the engine size.
You are right Steve. I recognized it as being a 12A170. But until I get home I don't have the means of looking up the rest of the number. I do know that Bill and I have both posted the complete part number numerous times in the past. Maybe OP use our search engine top of our page and find one of Bill's or My listings?
Ok, thanks guys, so is it necessary? The truck seems to run perfectly without it. Especially now that I fabbed the missing kickdown rod and replaced the coathanger throttle cable the PO installed.
