I I have an MTH SD70Ace. The TSU 1000 appears to easier to install rather than a Tsunami TSU-AT1000
The both appear to have number boards/ditch lights etc so is the TSU an easier install?
The TSU-1000 is the correct one to use.
I did a couple of them a year and a half ago and they work great.

Here's a thread I started in 2010 shortly after they came out. I posted pics throught the thread with things I found along the way. Note that this was a conversion from the Protosound 3.0 and not the DCC ready version. The DCC ready version will already have the correct polarity on the light boards.

Many thanks for taking the time to repy, I assume that all the ditch lights and number boards will work

Yes they should be fine. Just make sure the loco you have already has dropping resistors in place. IF you don't know then simply put them in until you figure it out.
