4-Wire o2 Install
Just picked up a obd0-obd1 conversion harness but i didn't get any instructions with it. So i've traced the colors to the pins and they are as follows.
Blue-A6- o2 Heater Element
Green-A17-IAB Solenoid
Black-A23-Power Ground <1v
Red-A25-Ign To main Relay
Black-B2-GND To CYP and TDC
Red-B1-Battery 12v+
Black-A26-Ground
Orange-D3-Knock Sensor
Yellow-D4 Service check connector
Grey-D6-Vtec Pressure switch
White-D14- o2 Sensor Signal
I've looked at RYwire's install page and figured out that A6 goes to one of the black wires(on o2), and D14 to the white wire(on o2)
. The other black goes to 12V switch should tihs be a25? The description for a25 is "IGP2 to main relay and to ground Yel/blk, Battery positive from Main relay, Battery Voltage with Key On Engine Off"
and the green wire to ground(i'll hook that to a26)
Does this look right? It seems to me like there are more leads then there need to be on this harness and i know some are made to plug and play with a Vafc or some ----, so i don't wanna fry anything.
