i found something hehe. ok well there are the 3 connectors on the ECU, you have the small one , medium and big, the big is on the far right and the small is on the far left

Your speed sensor cable is on the far right "large" cable color: PINK
And rpm cable is on the medium sized connector : Blue.

here is the link for further use, i may be wrong on the RPM. if its not that then its the yellow or red one

this one tells you the name for everthing and how it works
