some accords have them stock already...make sure first before you wire one in.

there are a few ways to do it. one is find the dead end plug and take the wire that comes from the ecu and go to the single wire on the box. the 4 wires left that match each other go to the 4 wires leaving the plug going to the injectors.

other way

each injector clip will have a common wire that is identical on each clip. cut those and tie them together along with the single input wire on the box. take the 4 remaining matching wires and go back to the injector clips.

just make sure you don't cut the other wire on the clips or mix up their order. the wire that doesn't match (different color on each one) dictates the firing order of the injectors.
