Ill do that Oska thanks.
Now I have one other issue. When I the other engine came with its loom, it has a second small fuse box which says its for fans. Presumably its for the thermo fans, but there is no where to connect it up too as the thermo fans are connected to the the original electrical wiring. (as in the engine loom is sperate to the cars electrical system. Do the thermo fans work on the engines loom or the cars electrical loom. if it works on the engines loom presumeably I will have to some how connect them in. The electrical loom has 4 wires the engine loom has 2 wires.
