harness question

[KSee777]

I'm putting in a A/F gauge in my 89 240. Does anyone know what color is the O2 sensor input wire is at the ECU?

u can tap right into it in the engine bay, u got ka or sr?

[KSee777]

KA24e.... yes I COULD tap in the engine bay, but why run that much wire when I can just run it across the dash.

yea i've had a an af gauge sittin around but dont want another wire goin into my engine bay. i alwasy forget to look in my FSM for the wire into the ecu. maybe ill get around to it today. the wire would probably melt too since the o2 sensor is on the other side of my downpipe

According to the 1989 Factory Service Manual the O2 signal wire is a solid white wire that connects to pin 19 at the ecu. hope this helps

out of my 95 FSM: for anyone with a KA24DE its the white wire in pin 46. i hooked up mine yesterday after having it for a couple months. this is for a KADE please dont get confused with the E. looking at the harness plug from where the wires are its in the second coluum from the right first white wire from the bottom
