Can someone tell me where the wire or wire harness in question can be located. My ABS light is on and I have already replaced the rear diff. sensor. I would like to check out the possibility of a this wire corrosion issue. - Thanks

 

you can check under the air filter tube . there should be your abs module. check for corrosion in/ on or around the wire plug. mine was the 4gauge red wire to that module. or you could just have a bad module

 

Thanks, will check it in the morning...

 

Well, I found the wire and sure enough it had a bulge about 1 inch from the ABS unit. Cut into it and got nothing out but green dust. I cleaned both ends back to good copper, tinned them and soldered them together. ABS light is now out (for now).
