How to use SSEEdit to replicate a patch similar to the Step Patch - CR - CACO.esp

[CCnoNed]

Hello!

I was hoping someone could explain how I could replicate this here patch between hearthfireextended.esp and Step Patch - CR - CACO.esp:
 

CACO converts horker tusks from miscellaneous items into ingredients, and the Step Guide includes a patch for hearthfire extended that allows that mod to use the CACO horker tusk resources rather than the default miscellaneous ones.

I need to recreate this for an armor patch that, i admit, is not part of the Step Guide. I modded my game using the Step Guide but have since added mods to my game and patched them accordingly. 

It's the exact same scenario, but with armor. (image below with more poorly drawn rectangle)

So how can i change the Item ID to "CACO_HorkerTuskIngr "Horker Tusk" [INGR:01CCA131]" without getting the "load order FileID9010 can not be mapped to FileID for file 'insert_your_patch_here'" error message?

How can i import, or call on a resource from another mod? In this case from this armor mod over to the CACO ingredient for Horker Tusk.

 

This community rocks! I appreciate any help

First, sort with LOOT.

Then load just the Step CACO patch and your mod ... the Step CACO patch will load its masters, including CACO, which is needed for the lookup.

Then you must "Copy as override into" (either right click the HE col heading in right pane or under HE in left pane ... or you could source it from the Step patch, too).

Select a new plugin (this is your patch).

Make sure your custom patch has no other references that override the Step Patch (or forward the item(s) from the Step patch into yours before making the change).

You must have CACO loaded to use the reference (double click on the value to bring up the picklist)

Woop woop!

Loading my mod with the step CACO patch worked like a charm! I was then able to see the CACO resources from the drop down, save it, and enable it in MO2.

Thank you for the thorough walk through!
