I have never really messed with wiring or transmissions. I have a 2006 tundra that has a broken 15 pin connector. It connects the ECU to the transmission. Both ends of the plug/harness needs to be replaced. On the ECU side of the harness, there is a broken pin inside the female end of the electrical connector. So it needs to either be de-pinned and fished out or new wires spliced in. Or replace the whole harness. On the male side of the connector it goes in to the transmission itself and connects to a series of solenoids. The whole wiring harness in the inside of the trans needs to be replaced.
I know of a shop that can do the transmission side of the repair for about 400$ I am looking for help on the ECU side of the harness. Has anyone on here messed with wiring or has knowledge on how to rebuild a 15pin connector?

Willing to pay money for your time.

 

The shop doing the trans couldnt do it?

 

they want to replace the whole harness from the ecu to the trans. I feel like thats extreme and they were talking about in the ballpark of a 1000$ or more. I think a simple splice or de-pin of the connector is an easier and more cost effective solution.

 

Old truck? Recently new?

Gunna keep it a while?

 

It's a 2006. I bought it only a few months ago, but I got it from salt lake city which explains the corrosion. I planned to keep it long term. I just did the timing belt on it so I plan to at least keep it 100k.

 

Here is a pic of the aforementioned plug.

 

would be cheap/easy to just jump the cable around the plug. Ghetto, but cheap/easy

 

No one has any experience or recommendations huh

 

Shops are hesistant to mess with old wiring harnesses because trying to make one repair can lead to other failures. I'd look specifically for an auto electrical guy - someone who ISN'T a toyota-specific shop - or, find an all-make Japanese repair shop and try your luck there.

Don't have any reccommendations for specific shops, unfortunately.

 

Thanks for the response Sybir. I went ahead and was able to fix the female side of the harness. I disconnected everything electrical from the rear of the trans to the engine bay and fed the harness up in to the engine bay where I was able to work on the plug and splice new wires in. The truck is now at Mr. Transmission in Roseville for the internal harness replacement and a full trans fluid flush. Hoping to have it back tomorrow.

 

Good luck, bud! I used to be super-scared of wiring and fixing connectors - getting a good set of depinning tools makes single-wire or small jobs super easy and way less intimidating.
