I'd replace it . You can also solder & heat shrink . Use lots of flux.

 

Here is another reason why I personally would not try to fix but replace. Its for a ECU. Some wiring is caring very sensitive voltage or resistant's signals. They can be like +/- 2ma at very low voltage ranging for a proper signal. Sometimes when you spice, cut solder/add wire it can throw off those very sensitive low voltage signals. With it being Steering....... I would Not want the Steering to go out of my control say going down the highway or with on coming traffic at say 70-80mph as a example.

Just me, but even at $100-$300, I would want to be sure my steering was repaired the right way. Not a patch job. Lighting wire with a constant 12v and ground, ok. Complex signaling steering not me.

 

This isn't rocket science skill level here. This is simply soldering in a wire of similar size (like 18-20ga) and boom, your done. A cold solder joint will not be ideal, for sure... but if you lineman's splice it first and then solder over top you're not in for a lot of worry. Like 909 said, lots of flux is your friend. Gob the wire in flux, heat it with your iron. Melt solder onto the wires by touching the iron to the wire and then solder to the iron and it'll flow right in there and cool how it needs to when you remove the iron.

Then again, I've got a lot of experience. Really, a couple butt connectors crimped nice and hard will get you to someone else that knows more about what they're doing. Just bring a 6-pack and a couple of cool stories and they can fix that for you and give you a safe and reliable connection.

Seriously, if you bring this to an experienced electrician this is a 15min job and isn't going to send you into a guard rail.

 

This? I am certain a experienced Professional Certified Auto Electric shop Tech who does things as they should be done, would Not even touch this trying to do a repair. When the proper way is to replace. They would not for lability reason being the 1st of many, many other reasons. Now it can be done yes. There is a right way and a wrong way always for things. But...... if one really has "experience"? They would just replace the connectors. That is what the Real "experienced" what do.

I care about myself and others riding in my car, to not want to lose the steering while driving. Knowing what your doing, and experience just don't go together with what really the proper correct repair of this. lol! Do whatever with a Lexus?





These cars are not 1972 Chevys. Not Rocket science but Technology.

I'm the automation engineer overseeing about 450mil worth of machinery in my area. I've had to recrimp connectors with a Leatherman because we didn't have the right dies on motors more expensive than a fleet of LFAs...

I'd solder that stupid wire in a heartbeat.

But hey, not my money. OP can do what he wants but he certainly doesn't need to waste his time and money here

 

If I told you I was a Network Fiber Engineer that repairs old boards soldering on my own it would matter not. I am, but that's not going to help the op. I looked a little to see where that clip tied into in the engine wiring, and he may not have a choice but to repair it. It may be tied into the main wire harness pretty deep. Getting a good Solder connection is sometimes not as easy as some think for someone who has never done it before. Its going to need to be very clean and done right to stay a good connected soldered wired joint.

He may be better off getting or using a easy wire connection kit like the 2 below that can be ordered from Amazon or picked up at many local stores. This would be the cheapest route even getting $5 el cheepo connectors and crimping them on a good connected tight crimp.


If that cut part is in the main Harness, another option is have the Insurance company pay the Tow to Lexus, let them give a high estimate, (complete wire harness replacement, + + + $$$$. Have them issue you the check, them find a cheaper shop to do the repair less your deductible. I found the below Image of it, but could not find the shop doc from Lexus at this time.
