Could somebody please id the plug in my pic please - the left hand one. Ive gone through my wiring diagrams and i cant find the stupid thing. Its on a 1990 Celsior , there are 4 wires going to it; black, blue/yellow,black/orange and white/blue
I only have a two wire plug in that location on my LS400.
The white/blue and the black/orange wires go to the coil above the A/C compressor if that helps.
The other two wires in your plug could possibly go to the crank sensor.
