Hi All,

I am trying to help my dad find the tach wire in his 2006 f-250 Super Duty. He installed a bulldog security alarm and everything works except the remote start which needs connection to the TACH wire. On there website it says:

On DIESEL Engines the TACH wire is a LIGHT GREEN/WHITE wire in a 5-Pin Harness held up with WHITE tape located behind the Parking Brake Release.

We have searched like crazy, but can't find this wire. Anyone know where this might be? Any help would greatly be appreciated.

Thank you,
-Allen

 

Clean Tach Out (CTO) wire is under the dash in the customer access bundle of wires. You may need to remove the PDJB to see them.

Here is a link with pictures and more detailed explanation.

Thank you for the quick response and link. Could you tell me what PDJB stands for?

 

Power Distribution Junction Box. Just remove the four screws and pull it forward.

 

The technical name for the "Fuse box"

 

Do you know what color the wire is? Thank you! Let me see if I can find it.

 

Light Green with a white stripe. Did you read the document i posted the link for???

 

OOps Sorry I just read the top post and didn't notice the bottom. Let me try to tomorrow and see if I can find it. Thank you so much for your help!
