Default Terminator x max install

Id first like to apologize if this is not a good thread for my question.

Hooking up the holley harness is easy. The problem is, what do i do with the giant stock harness coming from fuse/relay panel? Surely i dont just delete it.

How do i remove but still leave necessary connections? I cant find it on YouTube and its not in instruction manual. What am i missing

What's it going into?? You don't need anything for the engine anymore now that you've got the Holley. But again depends on what is going into

Everything to do with the engine in the stock harness can get pulled out then.

Oh boy. That's an octopus of wiring. I'd suggest getting a good wiring diagram and carefully go thru it to make 100% sure everything you're taking out can actually go. But yes everything related to your engine can get pulled out

The oem panel stays if you want the rest of the systems to work, such as the headlights, heat/ac, etc.
As mentioned, take out the engine related wiring, only.
Provisions for gauges will have to be made.
