Can someone show my the injector firing order for b16?

 

4 3 2 1
yellow blue red brown

 

The actual firing order is the same as the spark plugs... which is 1-3-4-2.

However, the poster above me has provided useful information to help identify which is which as well as the proper wiring colors to make sure that they in fact fire when instructed. The number one injector in a Honda is always closest to the cam gear end of the engine. On a B16, this means that the #1 fuel injector is closest to the driver's side of the car and the #4 injector is closest to the passenger side of the car. Wiring colors, again as stated above, are brown, red, blue, yellow from 1 to 4.
