Howdy...

I could use an assist on SJB repairs. On a 2005 FX4, the largest, upper connector (with the locking handle) has an intermittent connection to the dome light / supervision circuit.

Sometimes the dome light works, and then it doesn't. This is bad because the aftermarket alarm depends on that circuit. I can press on, or jiggle the harness connector and toggle the fault.

So, I would like to replace the connector, or at least disassemble it. I understand there's special tools for this, and I haven't been able to source the connector yet.

Ordered the Lisle pin tool... standing by...

I found these 2 diagrams for the 2005 SJB-body computer

Shows 4 connectors, I haven't pull one apart so can't tell you if this will be useful :)

Also included Interior light wiring, not sure if your alarm is using Door Ajar circuit, or Dome Light circuit

Many thanks, Ron. Which manual(s) are those from? I bought recently a Ford shop DVD from eBay didn't find diagrams like those.

They are from a College database, not sure of the original source
