Hey all,

So I had started going through the wiring on my s14 (I did not personally do the swap on this one) years ago. It ran but was kinda hacked wiring wise, so I started with ripping out the old and brittle harness. I?d be lying if I said I didn?t forget all the details since then. It?s an S13 red top in an S14 zenki chassis.

Long story short, I want to make sure I get the right ECU for this car. From what I can tell the wiring at the ECU connector on the harness I put in (a second hand WS harness) matches a 62/63 pinout.

I know the wire colors won?t necessarily always match but pin location/function would be best indicator. I made a quick spreadsheet (I tried to snip/attach as a picture but not having any luck) does what I?m seeing seem right? I have empty locations for pins 5, 10/11/12, 24, 26, 28, 33, 42, 44, 45, 102, 105, 111, 114/115.

If you have a good way for me to confirm by, let me know and I?m up for checking it. Been far too long really want to get this thing running again!
