I want to know for sure which each wire is. I have an 85 Si with the round barrel connector (not the 87 where they are flat and all in a row). There are two wires vertical right next to each other then one horizontal on top.
Looking into the connector there is Pink on top and then Green and Yellow side by side. From what I can find I think there needs to be a 5V power, ground, and return signal. I believe the Pink is the ground, Yellow 5V, and Green return voltage of the position. Is that correct?
There is an attempt at a diagram below.
Pink
_
Yelllo IT I Green
Any help would be greatly appreciated.
Thank you,
