Can anyone point my in the direction of one of these. The drivers pre cat male connector on the wiring harness is pretty badly corroded and I am having trouble finding a new replacement connector.


many thanks

 

I expect your best opportunity is to find one from a truck that's being parted out, with bonus points for a parts truck where the engine has been removed giving easy access to cut the connector from the harness with a long pigtail. My first thought is to try Will Tillery.

 

If I recall correctly, and I very well may not, but I seem to remember fronts and rears have inverse connectors. If that's true you could take the plug off of an old o2 sensor and graft it back into the harness.

 

Here is the cheapest and easiest product I found to replace a damaged O2s connector, works for either front or rear sensors. They are an identical match to our D2's, and makes it easy to extend the wiring.

 

This is your huckleberry. I used these when patching mine back together.

 

I saw that on Amazon and hesitated because I wanted to find the actual connector. Looks like the Amazon part is the way to go, just ordered.

 

I'd forgotten about those. But if the old connector is corroded you'll still be cutting and splicing, right? at least you'll end up with a lot longer harness-side cable. Be sure to zip tie the longer cabling away from the exhaust manifold.

 

Would be cutting but not splicing. Trimming the ends of the wires and assembling a new connector at the terminal end. Doing this would be my first choice if new connectors were out there.
