Engine Compartment Fuse Box R6
 

So in RAVE this R6 relay is listed as being for the glow plugs on a TD5. Does anyone know if this R6 relay is used for the SAI pump on the V8 discos?

Look on the lid of the fuse block and see what it shows.

Unfortunately that relay indicates you have to look in the manual. Which incorrectly (or incompletely) provides the information that it is for glow plugs. Based on wire colors in the ETM, I'm pretty sure that it's is for SAI. Can anyone out there with SAI confirm that they have a relay in this location?

My truck has SAI and an R6 relay. Page 239 in the workshop manual has a diagram indicating that R6 is the SAI Pump Relay.

Hope that helps.

Awesome! Thanks, I totally missed that diagram. I guess I need to order a couple of relays now. I borrowed that one for my heated windshield. I guess I should put it back. :D

You need to use the heated windshield in Arkansas in July? :p

Nope. Don't even really need it in January. Just thought if I didn't need glow plugs I would borrow the relay. I need to get a relay for my new fog lamps too, now that I've installed my new bumper.
