so i'm going through my wire harness, taking out things i don't need, and i'm going through the manual ( http://www.cochran-racing.com/FSM/s5/S5wiring.pdf ) and can't for the life of me figure out what the two yellow plugs that are about 1.5-2' upstream of the main ecu plugs go to. i have a green/black wire that runs to the middle of the engine with no plug on it, and i'm trying to figure out what the F it's for!

going through the manual, i thought it was x-23, but x-23 is located on the driver side according to the book. car/engine harness is from an s5 n/a. thanks

 

X-11 is yellow.

 

i think its x-10 and x-11, but im trying to figure out where those plugs go and what there for!

 

Can you see what the wire colors are for each plug?

 

X-11 is on page 28 and it connects to the harness coming off of the ECU which houses the injector wires. X-10 appears to be on page 32 and is a ground but the ground is used or not used depending on whether the car is Canadian or not?????????? That's what the diagram states.

 

the main thing im trying to figure out is what this single green with black wire is doing in the middle of my engine harness, chillin by itself with no plug. i bought the car "stock" but after tearing into it, it's not the original engine and the swapper didn't do a very good job.

x-10/11?


green wire in question - its at the very end of the engine harness, with injector plugs and a ground


where green wire goes into yellow plug


im trying to figure out what is the purpose of this wire.

 

The G/B wire is for the water temp switch for cars with the Additioal Fan System shown on page G-3 of the wiring diagrams. The series four also uses a G/B wire for the same purpose.

G/B on the EM side of the plug and mates with a G/R on the F side of the plug. Goes to the fan relay on the G/R wire.
