Take continuity between each Link and D2_4. Let's see if we can determine which Link is shorted to Ign Sw feed (I1). This is the only fuse link that is reading resistance. It was 2 green fuse links in one ring connector but I split them. This one splits to 3 solid red wires. Also, all other posts on the starter relay read resistance as well. It’s 18degrees our today.

Ωhm Posted January 19, 2020 Posted January 19, 2020 Good call on splitting the Links. Remove the fuses shown in the photo. I doubt you have power door locks. Do you still have continuity? Do you have foglamps?

Fog lights remain on when fuse is pulled(car running)
Bob89manche Posted January 20, 2020 Author Posted January 20, 2020 Solid red wire on the right side of this connector has continuity with fuse link bundle disconnected
High2by Posted January 20, 2020 Posted January 20, 2020 I think that wire feeds an under the hood light but not sure where it originates from.

I think my under hood light was ripped out at some point. Would be a blessing if it was still there. It seemed to have originated at the green fuse link that has been problematic. It is possible that this is incorrect as I had a helper with me at the time.
Ωhm Posted January 20, 2020 Posted January 20, 2020 A few months ago, maybe longer, someone asked about that connector. I looked up and down in the schematic and couldn't find it anywhere. Maybe someone knows, if so, can you put a connector number or explanation on it.
Ωhm Posted January 20, 2020 Posted January 20, 2020 Here's another view of Fusible Link H. Engine Lamp=Engine Compartment Lamp.
Ωhm Posted January 20, 2020 Posted January 20, 2020 Here's the only information I can find on the Fog Lamp Relay location. Schematic shows Front Lighting Harness.
Ωhm Posted January 20, 2020 Posted January 20, 2020 Trying to figure out way to determine which of the three (3) RED wires are the problem without cutting them. Remember I told you to stop cutting the wires, I might be eating (crow) my words now.

I had asked about it before and figured out that the solid red wire fed the under hood light but no idea what the red/white stripe wire was for. Sent from my iPhone using Tapatalk

Ωhm Posted January 22, 2020 Posted January 22, 2020 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.

Sent from my iPhone using Tapatalk Solid red wire from this connector goes into IGN coil. Red/white goes behind RH headlight through the loom. With this connector DC’d, no problem. With IGN coil unplugged, no problem. On the ICM, multi wire connector unplugged, no problem, singlular yellow wire connector unplugged, problem persists. Is it possible the short from yellow to red exista in the coil? I replaced this early on in the summer
Bob89manche Posted January 25, 2020 Author Posted January 25, 2020 Tested coil. It passes. After c102 is dc’d we still have continuity. Tore RH headlamp out, there is no relay back there. Seems Like all wires running behind the grill are all solid. No problems
Ωhm Posted January 25, 2020 Posted January 25, 2020 Do these color codes line up? C213_A=YEL C213_B=BLK C213_C=GRN W/TR -------------------------------- C214_B=YEL

Bob89manche Posted January 25, 2020 Author Posted January 25, 2020 This solid red wire is coming from suspect fuse link, running into the connector, and from the other side running straight into the ign coil. The plug in the middle of the pos and neg terminals that rest into the clips on the top side of the ICM.
Ωhm Posted January 25, 2020 Posted January 25, 2020 Photo of this (ICM) and RED wire, please. We need all eyes to see this.

Ωhm Posted January 25, 2020 Posted January 25, 2020 I wonder if that's the Engine Compartment Lamp connector. Regardless of what it is, get it out of there. Does problem still exist?

Dose problem still exist? Motherf***** . It’s 100% the lamp connector. No clue as to when it was plugged into the coil or by whom. I just took it as if it were supposed to be there. JC I feel like an idiot
Ωhm Posted January 25, 2020 Posted January 25, 2020 Go easy on yourself. When it comes to being an idiot, I often find myself over-qualified.
eaglescout526 Posted January 25, 2020 Posted January 25, 2020 HAHAHAHAHA. That was one of the first things I ever tested on my truck and wondered what it was for and I plugged it into the coil and it powered everything. That's funny. Glad it was that easy. But at least its not anything incredibly screwed up to where wiring has to be replaced.
