What are these clips for?

And where do they go? I know the one on the left is for a wiring harness - just not sure where.

2nd 2 look like they are from a relay??
First one I have never seen on my car?? Altho maybe wiring as you suggested & possibly on the front of the engine??

big one holds the dash wire harness under the steering column, installs at left lower stud of the brake booster bracket, held on with a push on star cut center thin washer like they use on brake drums.
has to be removed from the stud when  doing vac brake conversion  but doesn't need to be removed from harness

the other two are for the emission canister on the driver fender well, they clip into the bottom of the canister and allow it to bolt to the plastic fenderwell with 10mm bolts
