Driver fender well harness relocation gone bad
So after fixing my last issue with the oil pan, I found my low oil light on, turns out to be that pesky fender well harness. I've relocated this thing three times already, so I decide to dive in and chop the harness in two and run it in the engine bay. I labeled both ends as I cut them with numbers 1-58. After soldering and heat shrinking them I finally got to start the car, and nothing happens. No clickono nothing, not even my auto steering wheel telescope works. So I found two solder connections that were questionable and I butt connected them because I was out of solder. Alas my steering wheel goes to the correct spot, however the car does not start still. Tested continuity in all the wires I added from the start of the new section to the end and all are good. This time when I try and start it, not even my steering wheel comes down. Does anyone have any idea what I should look for tho fix this? I tries to pull the harness out from the car at the driver kick panel but for the life of me could not get it out.

you mucked a wire or few up, nothing else. We can't tell you where to look because your symptoms are far to generic and you haven't eliminated anything yet. If you found 2 bad connections you probably have more.
Also looking for toasted fuses/fusible links isn't a bad idea.

So I guess the Lexus engineers and the assembly guys at the plant routed that harness in the proper place then? Sounds like you need a new harness or good used one, and to route it where it is supposed to be????

you should consider keeping the harness in the fender instead of lengthening it into the engine bay next time.
While the fenders were off I decided it was the perfect time to tuck my wires. I managed to just unplug the harness on both sides and pull it up and through. Previously I would have just drill some holes and zip tie the harness up, but this time I made some small little tabs and tacked them in place.
I like this more then having the wires run on top of the strut towers in the engine bay

I tried doing this first a few weeks ago but my harness would not go high enough...the side closest the firewall kept getting chewed by the tire right before it went into the inner fender

Wiring diagrams are system specific, not what harness they run through. Lexus has diagrams of the harness locations and systems that may be attached to a particular harness, but figuring it all out would be a difficult task, to put it mildly.

Alright so for the past few hours I've been redoing the harness. I got all new wire as I was previously using the harness from another ls400 to extend my harness. I soldered and heat shrieked all 58 wires again. Now, the steering wheel works and every other feature seems to work.. Except for the car starting. I started searching for immobilizer issues as I believe that's what I have here. There's no power going to the starter fuse at the interior fuse panel, regardless of key position but I THINK I can hear the starter spinning, just not engaging. So does this sound like an immobilizer trick? I've tried locking and unlocking the doors 4 times, leaving the key in acc for 6 minutes, trying different key position combos with the battery disconnected/connected. Are there any other ways to reset the immobilizer?
