If your efi is similar to an EA the clutch switch and gear switch are used to cancel fuel shut off and lean cruise modes when either out of gear or when the clutch pedal is depressed.
The switches are wired in parrallel
Tells the EST box whether its in neutral and when clutch is disengaged so that motor runs accordingly. I think the clutch switch is related to emissions so that ECU knows when revs are going to drop, but I can't remember what. Maybe retards timing to reduce emissions?
Originally posted by (\/)ADXF Where abouts does the gear switch go on a Borgy Single-rail?
Should be terminals on box. Can't remember (and I only put new clutch in a couple of months ago and had to do it then) where, but I think it's around selector lever housing. Don't know if pre-EST boxes had the terminals, but obviously might not have.
Is there a return spring on clutch pedal? That should stop pedal going forward.
Here's a tip if you're working on an XF. The firewall is too weak for the clutch cable and it will flex and probably pull a section of firewall through in time. Mine went at under ?150,000. If it's a weld job it's expensive and it can easily be avoided. Get a clutch cable spigot from an XD/XE ($1 from Pick a Part if they charge you at all) and fix to the firewall the same as it's fixed to XD/XE. You could strengthen the area with a steel plate first if you want belt and braces security.
