93 honda civic cx
98 gsr b18c1 -
obd1 p72ecu ( just bought )

I know the pin-outs to knock sensor - Wondering where to run these wires to ?
and how do i connnect the IAB wires to the motor ? or ..

knock sensor - Goes into D3 plug, and apparently to a common ground. Do i cut the wires off the knock sensor behind the intake mani and run them into the ECU in the d3 and ground?

IAB - Goes into A17 i believe and EVAP into A20 ? but where do they lead to in the motor? Im not to sure how to run these wires and what to switch around...

Pictures will work best - reading ffsquad to h-tech forums. Need answers. Thanks.

Repin A20 to A17. The knock sensor is a single wire, run it to D3 at the ECU. Btw, if you're in Canada you'll have a firewall mounted MAP sensor on that CX, unplug the connector and plug it into the throttlebody mounted MAP sensor on the engine.

On the back of the knock sensor I take that wire n follow it to my ecu and plug it into d3 or do I cut n splice and wire one wire to d3?

IIRC that wire ends up at the shock tower plugs, cut it somewhere, splice more wire onto it and and pin it into D3

So just follow the wire from the knock to the shock tower, splice a wire but leave it still connecting to the shock tower, and wire another wire to d3

Just run it straight from the knock sensor connector to pin location D3
