Welcome, not too many from Tassie on here,
Spliced wire could have been a Haltech or something which is pretty rare as most people on here have an Ap or dyno tuning done here. What maps are currently on there I don't think there is a way of knowing.
For motor mounts have a look a Edge one of our sponsors ,JBR motor mounts are the most popular here or CPE.
With all your mods I recommend you get a Cobb app there will be a heap flooding the forum soon that way you can read your cars vitals and load a tune or start Etuning.
