Pinout for rear speed sensor (ABS) on 7M/1JZ/etc.. Toyotas

Hmm?

This is what I have.

[ABS ECU] -> [B3 Female] -> [B3 Male Pigtail] ...................... [Speed Sensor Male Pigtail] -> [Speed Sensor Female] -> [Speed Sensor]

So as I see it you lost / removed the following section of wiring when you did the engine conversion (as it was part of the 7MGE wiring loom) and you're trying to put it back in...

[B3 Male Pigtail] ......<engine wiring loom>........ [Speed Sensor Male Pigtail]

Correct?

I'm guessing you don't have the old engine loom to simply test to find out which pin on the 'B3' plug needs to go to which pin on the speed sensor plug? That would be the best and easiest way

Correct the loom is completely cut up and disassembled. I'm using a stock Aristo harness, extended, and spliced my body plugs onto it. Trying to add this sensor to the loom because the Aristo doesnt accommodate it (going to run new wires)

Thanks!

So you can't measure / trace the wires from the 'B3' plug to the ABS speed sensor plug on the old 7M loom?

If not why?

I found these in my travels...

From the 1990 TSRM. I think that perhaps the drawn ECT connection on the diagrams from the ABS ecu to the speed sensor is incorrect...

The pinout of the plug must be the male end as female are numbered from left to right, 1->x



It looks like you're right with you're pinout, but I think your number of the plug might have been wrong...

Pin #1) Signal (PSEN)
Pin #2) Power (RR+)
Pin #3) Ground (RR-)
