Recently picked up a well-loved 2000 LX470 to take my family a bit farther afield here in Northwestern Ontario.


It’s been great so far for getting in and out of the backcountry.

The previous owner installed custom rear drawers, a dual-battery setup, and a 2” lift/AHC delete.

I’ve since added an Ironman bumper, winch, and 285/75R17 Toyo Open Countries.

I’ve got two questions for the Mud brain trust:

1. Front torsion bars with Ironman bumper + winch

Pretty sure the torsion bars are stock, but I’m not 100% certain. The truck still has what looks like a normal amount of rake, but I haven’t measured hub-to-fender yet. The front end does feel soft with more brake dive than I expected — though it is an older, heavy truck, so I’m not sure what’s “normal” anymore.
Question:

With the added bumper/winch weight, should I plan to crank the existing bars or just replace them?
And what’s the easiest way to confirm whether my torsion bars are OEM or aftermarket?

2. DRL / high-beam tap for bi-LED retrofit

Up here it’s dark this time of year, so I’m doing a Morimoto M-LED retrofit on a fresh set of headlights.

Canadian-spec LX470s run the DRLs off the high beams at reduced voltage (around 6V), and when the actual high beams kick in they get the full 12V.
The issue:
If I simply grab a high-beam splitter for the trigger, the 6V DRL feed will still fire the bi-LED solenoid. I want to keep DRLs (both for safety and because they’re required here), but I don’t want them triggering the actuator.
Question:
Where exactly is the cleanest place to tap a true 12V-only high-beam signal so the DRLs don’t backfeed into the bi-LED trigger?

Similarly I’m probably going to add some driving lights to the bumper, I’ll want a tap location for the relay so they fire with my high beams. (With an over ride switch in the cab of course)


Appreciate any guidance — trying to get this truck properly dialed to not let me down on some winter adventures.
