Been there. on the oil pressure sensor. according to Cody at Caterham USA and a dealer-built Zetec SVT i've seen, an adaptor goes into the hole behind the filter. it adapts to the braided hose. the other end of the hose goes into a brass 'tee' (sort of looks like the 'tee' connector i used in the rear brake line). the 'tee' gets anchored on a threaded rod on the frame upper right just below the charcoal canister. the pressure sensor takes up one of the unused 'tee' connections. a plug is put into the other. Simple huh. Some time you can hear about my 'too short' battery cables. by the by, as i recall, it was difficult to get it all to seal - not leak in the first place and also glad you asked about it - mine needs to be tightened a bit more.
My throttle cable came with the engine as i recall. I can send a photo of the connection if you need it.
my W.T. Gauge went into a hole in my thermostat housing? at the rear of the block, driver's side. The thing with the cut wires is a mystery to me.
