ABS Module/Harness Wire Diagram

Hey there, wondering if anyone can point me in the direction of the schematic for the abs module wiring harness for 2015 Tacoma 4.0 4x4 TRD Sport DCLB.

Over a period of time I have had intermittent ABS/Traction control lights coming on the dash. Sometimes they would disappear for months on end and eventually come back. I had a buddy with a high end scanner pull the codes which were C1407 and C1408, which are codes for both left and right rear wheel speed sensors. Presently the lights have been coming on/off more frequently, so I figure I should get to the bottom of it. Before just running out and buying wheel speed sensors, I'd like to perform a continuity test to make sure it isn't the harness.... or even worse the abs module (900$). I found a schematic for the harness and wheel speed sensors on this site, but the harness on my truck looks different than the one posted...for reference, here is the harness that plugs into the abs module located under the hood on passenger side of truck. Thanks in advance.


For reference, this is the schematic I found, but as you can see by the 1st picture, my harness is different.

 

Most likely the sub harness for an intermittent issue. It moves a bit every time you move the wheel or the suspension cycles. Continuity test may give misleading results because of that.

 

I agree which is part of the reason I have put off resolving the issue for so long. I am hoping since it comes on and stays on more frequently that I could catch it. Would like to build a little confidence in isolating the issue before throwing money at it.
Appreciate the reply.

 

I got this from this site. Unable to locate the source. Credits to the original uploader.

 

I agree with this, alot of people have them break/corrode at the S22 connector where the 4 speed sensor wires meet up with the body harness.

Thank you, this appears to be exactly what I was looking for....appreciate it big time.
Hope to follow up soon with a resolution.
