Can I rewire speed sensor harness myself?

It's Slow
My passenger front wheel bearing on my 2000 GP seems to be throwing a code and the bearing was just replaced. The ABS light stays on all the time. I checked out the wiring to that hub and it appears one of the two wires are all corroded inside, I'm assuming the wire is broke where the control arm meets the subframe (common spot for the wire to break from my understanding).

So do I need to buy a new harness or can I simply run new wires of my own? They don't seem to be anything special.
 


Well I tried that and it didn't help, so I'm assuming my ebcm is bad. Oh well, I don't want to drop a small fortune to get my abs working.
 


On 2000+ Bonnevilles someone located a bad spot in their harness I think by ohming the wiring. It was literally corrosion at a connector that spread quite a way down the wires.

If you have that silly extension harness piece ... maybe consider trying a different one or running fresh wire to the ABS connector.

Yes actually my connectors are corroded at both ends, from the speed sensor to the body connector. I scraped inside them and sprayed them with electrical cleaner then ran the new wires between the two.

Autozone has new harnesses, but the picture they show does not include the body side connector, and of course the guy doesn't know if it comes with it. I'm going to have them order it and I'll have a look at it before I buy it.

This is the picture they show:

The code was for the passenger front being an issue, I do not remember the code.
 
Ok, so now I just need to know if that new speed sensor harness comes with both connectors or just the one in the picture.
 


But my connector has corrosion in it on one of the prongs and in that wire, so I need a new connector.
 
Corrosion inside both connectors of the wheel speed sensor harness, the wiring directly from the hub is fine.

Yes that linked wiring has the connector that goes to the hub, but I'm saying- it doesn't have the connector on the other side, going to the body- and my current connector is corroded so I can't use it.
 


Well that's what I did- I cut the 2 plugs off the existing harness and ran new wires between them. I have a feeling the connectors and the little bit of existing wire that's left from the old harness in the connectors still have enough corrosion in them to where current won't flow thru them.

So I'm saying I need new connectors also.
 
you soldering this? if not you should be.

strip the wires back till you have clean copper wire, new looking, not dull or brown, solder to that. use shrink wrap tubes to seal it up good too.

when i did my maf pig tail, i had 3 inches or less of wire till i was into the main harness.

if let go for a long time dry wire can travel a long way up the insulation.
 
Yes I am soldering and using shrink wrap.

That's my issue. The original wire that I cut that's left on the connectors is corroded inside, all of it, including the connector.

I really should have taken pictures. :th_shakinghead2:
 
i know what it looks like,( i was crapping myself as i got closer and closer to the main harness) just re do it, but strip it back till you hit clean wire. then it will be golden.
