when i got my 86 2.5 xj, there was not emissions vapor canister, so i pulled this one out of a Comanche and a buddy of mine hooked up all the vac lines. my question is does it matter to interchange them like this? will it work? and also my diagram says i should have a egr canister solenoid, but i dont, is it essential to have one? also i am questioning his ability to hook this thing up properly, can yall tell what lines should go where? i know the pics are kinda hard to tell, but from left to right i have one opening on far left, then in middle i have another which is capped off and the one under it has a perminant plastic cap, and directly up on top where the circle/cap is another (one yellow hose is going to), then further right is another opening. im pretty sure the circular cap is the purge and that should go to egr t'd into the solenoid i dont have. but not sure on the rest. just seeing if yall have a similar one to this one and could tell me how yalls is hooked up. thanks

 

ok so i located a vacuum solinoid and put in another charcole canister and hooked it up to proper locations. however as soon as i crank it up, the egr valve opens up and idles very rough. this solinoid is out of a junk yard, is there a way to test it?
