Yes, they are. The wiring harness from my F22a1 engine pluged directly into my H22 ECU. My friends GSR ECU also plugs directly into my wiring harness.prelude styl said:actually, the f series (I only specifically know of the F22A1) isn't the same as the H series ECU clips.
The plugs sgould be the same size and shape, even if all the wires were not in place on your S harness. Maybe your car is just a freak of nature?prelude styl said:Well, my previous Prelude, a 92 S, didn't have the same ECU clips as an P13 ECU. Maybe mine was different, I dunno. I'm not arguing, I'm just saying, that's how mine was.
