What we got, IGN SW (I1) YEL shorted to B+ Hot at all times Fuse Links. Separated Fuse Links and found one with continuity between the two (2) circuits. But this Fuse Link (GRN) has three (3) RED's coming off it and we believe it to be Fuse_Link_H (FL_H). FL_H feeds Engine Compartment Lamp (Engine Harness), Fog Lamp Relay (Engine Harness and Front Lighting Harness)and a busbar on the Fuse Box (Engine Harness and IP Harness).
See if you can inspect RED wire for Engine Compartment Lamp for short to YEL. If you can trace the whole thing and prove it good, no need to cut it.
Disconnect Front Light Harness (C102). Check if you still have continuity between D2_4 and suspect FL_H.
If continuity still exist, can you trace and inspect RED/YEL from suspect FL_H to C102 for RED/YEL short, otherwise, we can eliminate the IP Harness to help determine next steps.
