when i took off my injectors, i fuxed up and didnt mark which ones were primareis and secondaries (the injector clips).

help.

 

disconnect the DB-37 connector at the MS, then test either pin 32 or 33, they should have continuity with the one of the leads on the primary injectors. (use ohms, when there are 0 ohms, there is continuity.)

32/33 are the cyan leads on the bottom right

You can do the same thing for leads 34/35 and these are the secondary injectors
