Auto Parts: Question on value of parts, mazda pickup, ford ranger

Question

2000 Ford Ranger recently had my engine on a 2000 Ford Ranger, 4cyl. 2.5l. pickup.  automatic.  replaced with one from a 2001 mazda pickup truck.  I have some extra parts left over from the switchover, that they didn't need with the new engine, is there anyway to find out if they are worth anything? or if I should just chuck them in the trash?  the parts are (and I may not get the names right) The Wiring Harness, The Torque Inspection Plate, Electronic Coil Module w/the alternate mounting bracket and water pump.  I appreciate any thoughts, they've been sitting collecting dust, and would love to know if they have any value, thanks again.  picture attached...

Answer
    I can't imagine anyone wanting to buy any of this stuff.  It's used and kind of random.  Of course, if it were me I'd find a place to stash them on the off chance I might need them later.  If you saw the collection of stuff I've accumulated you'd realize the likelihood of ever using old parts is just about zero.
