Greetings guys.
On my FZJ105, 2003, Base model.
I am just cleaning up my Oil pressure sensor and air con wiring lead which a mass of bodged up tape and non-toyota shielded cable.
On the bulkhead connector I have 3 wires - white for oil pressure sensor, what looks like yellow and black for air con but there a third wire which is white and black - where is this supposed to go?
Plugs for oil pressure sensor and air con only have one wire each so not sure what the third wire is for?
Thanks for your help!
Cheers Robin
