Having a little issue with the ..9 - Residual heat relay (yellow/ green) connection. Is there another name for this relay
even drawing a blank on auto data wiring diagram? Any idea on location please?

As my T6 did not have aircon from factory, i guess that i will need to fit the J708 and wire in the whole circuit. Would that be right, as i cannot find that relay on my vehicle?Relay carrier behind dash panel, right, right-hand drive (L0R)

Sorry i have just found the 646 relay, thank you!
Does your van have auxiliary/supplementary coolant heater (Webasto) - if so, then the relay is there, even without factory AC.
The "646" is just relay type - there are plenty of those. Is it in the exact location?
Oh thanks...no my van didn't have an auxiliary heater from new. The unit pictured it not on my vehicle.
This is my o/s fuse relay board
Would that mean that my van would need the residual heater relay installing into the fuse box?
Intriguing... actually even vans without auxiliary heaters have this J708 relay - found under "Residual heat and heater support whilst driving, no auxiliary heater (9M0)" however I just can't find wherefrom the relay gets the input without AC or aux.heater.
Do you have the "9M0" on the configuration label?
Can you see what colours the wires into your relay are?

Well, the reb/blue wire suggests it being the Residual heat relay. However, then also one of the black wires should have a blue stripe on it (going to Webasto!!).
You could remove the relay and measure resistance between relay socket pin 3A and ground if there is "circulation pump V55".
The aircon feed is the leftmost=grey/white in the picture - it would replace black/blue (coming from Webasto!). If this is correct picture for your van the rest of the wires are already there.
This picture is for a van with Webasto (*4=without AC, *2=Climatic AC)
