Turbo Drivers Connector/Harness

[David Ruiz]

LC200 2010

Everyone, I have a situation where the connector plug that comes from the main harness has been damaged. My buddy lives on the beach and during the rainy season, he has to drive through salty water to get home. The connector has been damaged by the salty water and needs to be replaced. From what I can tell, the entire harness has to be replaced but the dealer says that they are not able to get it anymore.

I was thinking that maybe if I was able to find just the plug from a car that has been crashed at a junkyard, I could replace the plug only, has anyone done that? Has anyone moved those drivers to a different location?

Thanks in advance.

Looks like you need to replace the terminals in the connector if there is saltwater damage (corrosion).
That means not only repining the terminals but also replacing them with good condition ones. The terminals/connector could be available from Toyota and then you replace corroded terminals in the connector unpin-cut-crimp-reppin. If you get a junk yard one the process after unpinning the terminal from the junk yard connector is unpin-cut-solder-reppin.

I have not repinned this connector but in general connectors can be repinned. Watch the videos on YouTube and get yourself the tools (they're cheap).
Theoretically most connectors can be relocated depending what they are plugged into. If it is a connector between harnesses, then just cut the connectors leaving enough pigtails to solder new wires to them, and extend the harness with new wires to the new place. You'll need to use soldering and/or crimping as needed depending on the curent we are talking about, and you'll have to waterproof those.

This is the general idea. The actual work depends on the actual details.

Awesome! This is great information. I have not repined factory connectors but it's probably similar to other aftermarket ones.

Again, thank you and I will let you know what I end up doing to get it fixed.

Not sure about this specific connector but on others, the OEM connectors are available and the split kits that cap with them are also available. If you need to repair/replace the pins you need the splice kits which are really just short lengths of wire factory pinned for the OEM connector. You cut back the harness wire to cut out the bad part and splice in the new wire with the new pin and then install the pins in the connector. When I went to go do this on a connector the splice kit wires were expensive like $8 or $10 each so for a six pin harness it added up plus you had a wire splice. It’s possible to find the pins that will work with the OEM harness, but you really have to search then you can make your own leads, but you have to have the tools to crimp the pins.

Alternatively, you can cut the OEM connector out and replace with the male and female sides of an aftermarket DT type connector. For the connector dealing with it appears there’s different gauge wires and you may have to turn that into more than one DT style connector. You will still have to have the crimping tool to crimp the pins onto the wire leads.

The tough part here will be if any of the wires are shielded, though I would think so for a turbo actuator.

Also for the record high quality crimps are better than solder in the long term.

But whatever is done you’ll want to take a serious deep dive on how to make all of this weather proof. If the salt water is getting through a factory Toyota weatherproof connector, it’ll get through most of what passes for acceptable harness repair work these days.
