bit of a random one I bought some dials off a guy on the facebook forum they've turned up all good condition there the ones that sit in the three pod holder on the dash. The oil pressure one has a loom Coming out the back with three wires leading to a connector now the only thing I can see for oil pressure is just under the alternator but it only has one connector ive got a classic 94 wrx they came off a facelift classic. Sorry for the read any help or pics would be great.

You need a t piece adaptor, you remove the original sender pop the adaptor in and then put new and original one in the adaptor

Thanks for that but was just wondering if I was correct in thinking that the sensor only has one connector even on te facelift models.
