I have the "Restricted Performance" light on my 2006 XJR, and dealer says I need the SC Aux Water Pump.
After reading some posts, I can't tell which ones will plug directly in without needing any wiring?
Thanks

 

You might wanna tell us what you have read so someone can advise. I have changed both pumps, but I didn't try to find the Ford or Bosch equivalent.

Check the fuse F 31 under the hood. Key on should be 12 volts. Super charger pump runs all the time. Aux pump which is by the coolant tank is for the rear heater. As far as I can tell is on when needed.

 

Thanks, definitely referring to the super charger pump.
R/P comes on intermittently, usually after a little work out, so fuse is alright.
I've seen reference to Bosch and Johnson Control pumps so I'm hoping someone
can help with the Model # and which one just plugs right in.
Thanks
