OBD port not connecting

Recently I have run into a problem with my OBD port not connecting, ever since I have bought the truck the OBD port was touchy, I work at a dealership so I was there when they inspected it previously. Fast forward a couple months I took my truck to get the OTT tune, and the guy said he couldn’t do the tune because the OBD port is connecting then disconnecting and he wouldn’t want to risk frying the ECU. I took it to Toyota 2 days later to get the port looked at and they quoted me $5,000 for parts and labor to fix the issue, they said older OBD port connectors would not connect properly and newer style OBD port connectors would connect to my truck just fine. They told me I needed a brand new dash wiring harness. And of course I said no thanks because for me the tune is a must the only thing that is mandatory is my inspection once a year. So I left it and now when I need an inspection everyone got new inspection machines and they will not connect to my OBD port. So I just find it hard to believe there is nothing I can do besides getting a brand new wiring harness they told me at the dealer as well that if I were to buy a new connector they will refuse to install it bc it is very risky and I could lose data that is held in the wiring or something along those lines. Either way there has to be another option, does anyone have any ideas?

 

If I am understanding you correctly and the physical plastic connector under the dash is bad or the pins are damaged those can be replaced pretty cheap... Amazon for ~$15 ish

 

I have the actual RO in my truck I’ll have to grab it to get specificly what they said. From my understanding they told me I could splice in a new connector but it would be risky and they wouldn’t do it for me because of it, or replace the entire harness.

 

Might find better information in the 3rd gen forum this is the 1st gen forum
