Unswitched heavy power under hood

[Coachgeo]

finishing up a swapped swap. (replacing swapped engine.. with same but newer engine). My glow plugs needs a full hot (that will be switched on by a relay). Unfused is fine.. I labeled a lot of stuff prior to pulling engine..... but tags all faded and I cant read it anymore. go figure.

Does one of the two front heavy wires mounted with screws in the PDC actually a full time Hot? I dont have a battery in there yet to test.. I would rather not go straight to battery but guess I could.

Could swear the Previous owner had this under one of the screws.... but not for sure. I do know it is the hot line though based on the MB pin outs on Glow Plug Relay.

If you are referring to this, it does connect directly to the battery. [The red wire shown is for the harness that powers my headlights directly from the battery.]

Perfect thanks.... PO's previous wiring was so janky but done in the right spots... Will add a ring to the wire and put it there. Thanks.
