Lightbulb HELP!! DC5 swap, O2 wiring

Anyone knows how to wire the DC5 O2s into the 7thgen. I have a LX with a DC5 motor, and I tried wiring this **** but to no luck. So far its running with no O2's but isn’t drivable because the ecu is throwing in so much fuel because the O2 aren’t wired. I have seen some stuff on here before about wiring the c101 harness (Already did that wiring) but it doesn’t say were to hook up the O2 to? Please Help.

The problem is wiring in the A/F sensor relay or as hondata calls it the O2 heater relay. Where is it? i have the O2 wired to the c101 but it still throws a primary O2 MIL.
