Whats the relay for located in the main engine bay junction box?
Any body know a source for good T25 wiring diagrams? Are Haynes any good?

Thanks

Glow plug relay if it is a Diesel?

I presumed mine was originally a petrol but I could be wrong as it was converted to Ford v6 back in Germany many years ago.
Does a genuine petrol van not have any relays in that junction box?

It is for the inlet manifold pre-heater (under the carb)

Thanks for that, so its probably not used any more and certainly wont be required for my Subaru conversion.

Does anybody know what feeds i should have coming into the engine junction box and what should be returning forward. Only engine functions i mean , not lights etc.

My wiring has been butchered and im trying to identify everything
