help!

ok ill start with my car is a 1g mk3 supra with swapped 1j

my problem is three connectors I do not know where they go and I cant find my front knock sensor clip/wire
I am not sure if it was the hack job the guys done when I had my motor wired in and those clips are for nothing
I went through their work and all they done was taped the wire together
any ways if anyone could help me out I would really appreciate it!

the three clips are from the main harness from the ecu

First one looks like for abs.

Last one looks like oil pressure.

Second is could possible be o2.

I don't have abs on my car
ill check and see if the second goes to me oil pressure sensor
and the last one isn't 02 cause that's already hooked up
thanks hvyman

Get a meter and read each pin to the ECU plugs end to end and you will find out exactly what they are wired to, at least for one and two. The 3rd will go through the M1 plug if its for the oil pressure.
