I removed the TA in less than 20 minutes. I went home at lunch and pulled it out so I could cut into it and verify the bad wires. I wanted to get one on order the same day. I had the new one two days later and installed it in another 20 minutes. No kidding - it is really that simple.
Don't forget to order the gasket that goes between the TA and the intake manifold. It's only 2 bucks.
Experience is something you don't get until just after you need it.
