Btw if anyone can figure out what pin 2 on the 10 pin connector (white purple) is can you please msg me so i can update it.

i hate that there is no edit button...all pinouts are ecu side, not engine side.

Good info here so I'll contribute.

"White / Purple" on the 10 pin harness (C213/C102) on my harness is just White, and it appears in the Helms as white as well. It goes to D14 O2 sensor on all but the wideband VX's. (92-95 Civic Helms 11-14)

Found a mistake. White/blue is marked as VBU (voltage back up) pin D01 but it's actually TDC B14. The voltage back-up is indeed white/blue, but it doesn't go through C213. That wouldn't make sense anyway. It goes from the under hood fuse box to D01. (Helms 11-17)


I'm putting a VX engine into a CRX Si using the original VX engine harness and creating wire harness adapters at the strut tower plugs. I'm using an OBD0 to OBD1 jumper harness to run the VX ECU.

If I find any other discrepancies, I'll post them up.

*see edit Alright, I don't know what the deal with the 14 pin harness (C212/C103) is, but it's only about half correct. Maybe it's from an OBD2 Integra, I don't know. Maybe he tried to match up the colors to the ECU pinout he posted below. Many of the wire colors are different and several of the connections or wrong.

Here's what I have (Helms 11-14, 11-15). I don't have the plug in front of me, so it's in order that they appear in the Helms. Again, this is specifically for the 92-95 Civic:

ORN/BLK O2 A6
YEL/GRN MAP D19
WHT MAP D17
GRN/BLU (GRN/WHT) MAP D21
RED/GRN (YEL/GRN) IGNITOR A21 and A22
RED/WHT TW D13
RED/YEL TA D15
YEL/WHT TAS D20
LT GRN (RED/BLU) TAS D11
GRN/WHT TAS D22
PNK (BLU) or (WHT/YEL) ALT A16
ORN/WHT (GRN/YEL) VTEC A4
ORN/BLU (BLU/BLK) VTEC PRESSURE D6


*edit Looked over his work and it does appear that he simply attempted to match the wire colors up to the ECU pinout wire colors. In some cases, there are multiple wires with the same color, and it appears he stopped at the first match he found. It's remarkable that he got so many right. I'm very glad that I verified this info before relying on it.

You're welcome, internet!
