Eg b18c wiring

Hi Guys,

have a b18c obd2a in a eg obd1(i think ? someone confirm?)

to have the wiring done i could use

OBD1 & OBD2 VTEC Subharness
Rywire ecu jumper obd2a to obd1

No cutting or anything - plug and play everything

Is this correct?

Depending on your EG as to how many wires you will have to join up. It will mostly be plug and play however you will have to run 3 or so wires.

it was a gli eg non vtec obviously.

are you talking about the knock sensor wiring that would need to be joined up?

With a GLI you have to wire




VTS VTEC Spool
PO2H Primary Oxygen Sensor Heater
KS Knock Sensor
PSPW Power Steering Pressure Switch (JDM only. You don't have to wire it.)
IAB B18C2, B18C3 Engines only (not Type R)


Usually wire from the ECU to the 3 connectors at the LHS Shock tower.

So-
OBD1 & OBD2 VTEC Subharness
Will do
Vtec spool?, Vtec oil pressure knock - what is KS knock sensor?

PO2h Oxygen sensor - have to manually do it (3-4 wires total depending on the plug right?)

PSPW - dont have

IAB not needed.
