Connector Teminal Repair

[fj40toycruiser]

For details on why I need this take a look at my other thread. 93 80.

Anyone Ever See the A/C System Amplifier?

I need to replace some terminal that somehow have broken. Specifically the female spring like portion that pinches the male pin has been damaged. I am not sure if there is some type of magic fix that would work without replacing the terminal. Or I need to know how to identify, source, and replace the terminal's in question.

Can you get a pic of the end? If so I can look it up in the Toyota Wire Harness Repair manual. Then you could order a pigtail from Toyota that you could splice in.

All of the individual pins and most of the connector bodies are available from Toyota to do it "right". There is a PDF document floating around that has all of the part numbers and repair procedures.. you'd need to get a non-insulated small terminal crimper and to ID the type of pin in use, but with that you could basically make it as-factory.

Another option is to get the pigtail cut from a parted out truck and solder or splice in the needed wires.

Yeah pm me if you want the pdf to look it up yourself.

Hope this helps..

Good writeup on how to do the search.

Not trying to ruffle feathers. If I wanted to replace a connector I would order any sort of connector set that would be installed on an Isuzu Trooper, mid-90's and up, and just put it to use. The connectors Isuzu chose to install are the best I've seen. Absolutely airtight. Two or three rubber flanges on one plug to block out intrusion of anything. When I replaced all the sensors on my 93 back in 2011 I found 100% of the contacts to be unadulterated. Pristine. I was shocked.

No voltage-blocking dielectric grease required.

Religious adherence to Toyota's approach to connectivity will do you no good. Toyota rules overall, but FAILS in connectivity. Isuzu got this stuff right all while designing crap engines and transmissions.

 

[Allen9480]

Speaking of crap Isuzu engines: Isuzu once released a TD on how to deal with sticking hydraulic lifters. Isuzu's answer was to go to Autozone, buy a bottle of CD-2 and pour it into the oil. See what happens.

I haven't had any issues with the sealed connectors in the engine bay but I've got a bunch of corrosion on the connectors that are in my footwell. Probably should've been sealed but aren't.

Exactly. As I said, Isuzu did connectivity right, bumper to bumper.

Any pics of the types of connectors they use?

I have no pics. Nonetheless, just take any Toyota connector and add two to three layers of silicone flanges on one plug. Once the two plugs are conjoined nothing can enter. Nothing but electricity.

When I was replacing the sensors I felt like I was opening a time capsule.

 

[Allen9480]

I'm reluctant to steamclean my 94's engine bay based upon the nightmarish issues I've read about in Mud. This is because of the weak or non-existent connector sealing. I will NEVER use dielectric grease to accommodate poor connector design.

My 82 Porsche 928 loved a nice bath here and there. No failures. No corrosion.

Cool. Tell us about your connectivity. How do you do it?

There's constantly someone sharing a pic of contacts greener than the Statue Of Liberty in here.

 

[fj40toycruiser]

The problem with replacing the connector and even the contact terminals is the location. This is behind the radio with about 1.5" of wire that moves deep into that cavity. Crimping is out of the question as I can barely get the pick & small needle nose pliers in there to remove the terminal from the connector housing. If I can replace the pin I will have to use pliers as the "crimp-er" which I am not very fond of the idea.

These guys should have what you want, I bought a few ends from them.
