06 srt10 tach signal wire?

[getbit06srt]

I found plenty of threads for 04-05 tach signal wire, but not on the 06. My stock tach is starting to act up so I'm putting in a mopar 5" tach. I think the top plug at pcm, pinout 18 might be tach signal but need to confirm, please help

Also, Clean off all dielectric grease on the back pc board. a pain, but it worked on mine.
Or,
get a new tach !
