I checked out this thread--> https://honda-tech.com/zerothread?id=945557 and still cannot find my answer. What plug is supposed to be on the end of this wire? Also, is there an equivalent plug on an obd-1 b-series harness. Another question that I have is there was a one pin connector, and the wire broke. Where does the single pin connector plug into?

 

Oh, is this plug for the coil wires(which obviously I will not need on my b16 swap)?

 

the single wire plug I am talking about is this one on top next to the 2 wires not in a plug:
Is this for the reverse lights?

 

im pretty sure the reverse lights are the ones that dont have plugs. the single plug is coolant temp. the very top single wire is o2 sensor. one underneath that goes plugged in the head.

 

good to know. i wont need that one for the o2s because I am running obd-1.

 

another question: what is the 2 pin thing on the back of the block for? The one pin is knock sensor....

 

bump...is the 2 pin the fan switch or the oil pressure switch?
