Are those plugs for the injectors from the 86.5 harness or the cut harness?
The injectors look yellow to me so might be the JDM ones which won't work on a US harness. Take a look at this link and you can see the difference between the JDM plugs and US plugs.

US uses plug F and JDM uses E for 7MGE.
If you have the yellow ones you will have to get a set from a junkyard and don't forget to put new O rings on them.
