Default 03 LS430 - Disintegrated Electrical Connector

Hello,

After pulling the intake manifold I found a disintegrated electrical connector. The middle section is still there, but the shell around the plug has fragmented. Basically there is nothing to hold it in except the rubber part of the plug center.

Does anyone have the part number for this item? Can this plug be repaired? This is on the underside of the manifold and I don't want to have to do this job again.

Thanks.

Found the part number. The harness comes with the VSV valve assembly - 25860-50121.

I found the part numbers for all the electrical connectors in our cars somewhere when I had to replace a few under the hood after doing some work. I also found a document that gives information on taking the connectors apart so they can be replaced. I thought I save it somewhere but i cant find it. You can order most of the connectors from lexus or even find on ebay. A lot of the connectors are used in multiple spots. The plugs actually have their part number stamped on them. If you have the tools and know how you can safely pull the pins and plug them right back into the new connectors.

Thanks for the info. I was wondering where I could order the connector from and which one to order. This will help a lot. However I decided to order a new VSV valve, which comes with the harness. I heard that this valve can fail with age and I had to pull the entire intake manifold off to access it. Also I don't trust my repinning skills right now. I'll try and practice on an easy-to-access-connector.
