Ok, thanks. Will go and see Gryphon Engineering here in Cairns. Was hoping I could work this out myself, but I am hitting a brick wall and need some guidance for this bit.

Also, have you got the Transmission Fluid temp sender installed? I don't have one yet, but am considering it.

The coolers are huge! 300mm x 300mm and there are two of them. Took a whole lot of mucking around to fit up.
