I picked up an '85 6.2 yesterday for FREE but know little about them except that I wanted one. Can anyone ID this box in the first pic & the part with 5 pins located between the oil fill cap & the thermostat housing?
I should know this 

Damn you must have been like a second fasterThe box would be the fuel filter. The other thing Im not really sure about, might be cruise control related.
We posted at the SAME time
The square thing is the primary filter and the part with the pins is for cruise control

The second pic is of the cold advance, high idle when cold (HPCA)
I was expecting the screw on canister type fuel filter.
maybe thats also why my cruise never worked...I didnt have the module there in the first place.
Those are found on the other side of the IP.
and thanks for the correction
