What *I* would do, is unplug the o² sensor, and create an extension cable ie. buy a plug, socket and a length of 5 core (or whatever) cable. That's what I'm thinking of now. Any ideas where to find the connectors (as in in-store)? you can buy the o2 plugs from toyota (i made a thread somewhere with a link to the toyota wiring manual) and source the crimps on jaycar
