this is near the beging of the harness (where main connector is)



here what is the yellow wire for looks like next to conncetor for trailing coil? also i dont seem to find the other conncetor on the harness that goes to the trailing coil as well.



and not sure what these are?



i bought the haltech used obviously for my fct2. the prvious owner doest remeber some of the stuff since i bought it a few months ago and just now got around to installing it

 

according to the wireing diagram the yellow is either the CAS trigger or it could be the MAP wire , the green is CAS home or an auxilliary input

and the white 4 pin connector looks to be the CAS plug

you never know what hacks or splices someone has made to a harnnes... the last person could have spliced a differnt color wire in ... best way to make sure which wire is what is to do a continuity test using a muli meter and test the pinouts
