Getting ready to change o rings on injectors,I have most info so far except how do the wire harness come off the injector,just pull off?, and what do I do with these clips on the rail,do they just pry apart from the injector and then pul the rail off?Its a little cold out so I don,t want to get in a panic and break a clip off or something.My only expeirence is with hose clamps

 

You can leave the electrical intact to change the o rings. Just unbolt the rail and yank it out (yank hard) All the o rings are on the tips. This will save you a load of time too.

 

to get the electrical connectors off there is a type of c clip on there (silver wire on the top left corner of the highlighted red box in your picture) then to get the injectors off the rail pry the metal clip off (the one circled in red on your picture)

 

will that pull the injectors out at the same time?
