Hi All,

Could someone give me some detail into the 3 main plugs that come off the engine electrical harness? I have 3 sets of plugs (AP1 engine) photos attached:

Gray
Dark blue
Light blue

I am most focused on the light blue plugs as that is the one that is not able to be plugged into my standalone EMS.
Thanks!

I think that light blue connector is called C101 and it normally sits just bellow the ecu.

ok. I think i didn't fully ask my question.... what does that power/measure on the engine? temp sensors? fuel pressure? etc

as in, if i dont have anything plugged into that.... what will i be missing out on?

You should probably get the electrical manual if you are thinking in those terms.
Here is a thread with the pinouts for that connector https://www.s2ki.com/forums/s2000-un...nouts-1068904/
