The High Beam Indicator Module:

So you bought the Koito Headlight Upgrade Kit - "the best $60 you can spend on your FJ40/60" - but now the indicator for the high beams doesn't work. Annoying! Here's the fix. This has been designed to work seamlessly with Toyota's stock wiring system for 1981-1987 FJ60s. Schematics were perused, engineers were consulted (thanks Ross!), many calculations made, and many tests run. Plug it into the empty stock headlight connector on the driver's side of the truck. That's it. It works.

Safety features have been built into the HBIM:

1. Almost no perceptible heat generated (this is not a load resistor; that is not what was needed to solve this problem).

2. Time-delay 5A fuse built in. This thing will blow before the headlight fuse on your truck. If it blows please inspect your truck's wiring first, then purchase another HBIM.

3. Reverse current and flyback/voltage spike protection.

4. 0.41A theoretical current draw. Early units testing at 0.36-0.39A actual and <1A on/off current spikes. Very low power consumption.

5. Potting compound dampens vibrations, protects sensitive electronic components inside, is oil resistant, and is safe for -40C to 93C temperatures.

6. All components safe for -40C to 105C.

7. Incandescent and LED bulbs rated 5W or less will work.

8. For use in 12V systems only.

Further testing is needed but this should work for 1979-1983 FJ40s and possibly earlier, and it may be able to be adapted for use in the FJ62 with certain wiring harness situations. No guarantees on those so buy at your own risk and report back with your results. Updates to follow as I find local trucks to test.

*Please note, Cruiser Trash Parts assumes no responsibility for the 30-40+ year old wiring in your truck or any consequences resulting from corroded, mis-wired, or non-stock wiring causing damage when using the HBIM. With an emphasis on safety, the HBIM has been designed to fail at a very low threshold with a time delay 5A fuse that will activate before any damage can occur through it's specific circuit. The operating current is well under 5A so it will have no problems functioning in a system with decent wiring. If your truck burns down I can guarantee it was not this that caused it.
