Hemi swap wiring

Cheers for the information, yea main reason i ask is there is a hemi for sale near me with the terminator x. Looked appealing as you use cable throttle and pretty simple plug and play, as ill be using 904 anyway. Cruise would be easy to set up as could retro fit a late 90s Holden one that are push pull style unit that simply hook up to throttle. Not that ill need it.
Not sure what the best engine loom would be to buy as see lot of mixed reviews. Terminator x good for 650 hp and only shooting for 550

I forgot about the option to run a cable style TB with the Terminator. Can’t do that with the OEM computer. A cable style TB would be easier with the 904 as it needs a kick down setup of some type unless you run a full manual VB. But not impossible with the drive by wire TB either.

When you say “best engine loom” do you mean the harness or the covering over the harness?
