Broke my 2H tach sensor wires. Anyone know the part number? I can’t find it on toyodiy. Anyone got a spare? Anyone successfully re attached the wires? Thanks

Pretty sure its: 83180-60040
Had the same problem. Replacement part is $$$ so I carefully removed the resin around the wires in the sender unit and soldered on new wires, then used hot glue to waterproof it again. Been running fine for 3 years now. Cheers
Here's an Aussie vendor selling the sender unit: Genuine Toyota LandCruiser HJ75 HJ61 RPM Revolution Detector Sensor Sender | eBay - https://www.ebay.com.au/itm/195361851548
This one 100 AUD cheaper but still $$: Toyota LandCruiser HJ75 HJ61 RPM Revolution Detector Sensor Sender Genuine | eBay - https://www.ebay.com.au/itm/155508860002
I have always wondered if it would not be possible to use a generic sender unit using the same Hall-effect principle. They all have 2 wires, essentially sending out a pulse for every revolution, no? The only thing to watch out for is the distance to the fly wheel, but you can get them with adjustable depth. Something like this
It might be pulses, but it also might be the case that the OEM sensor isn't sending pulses like we're used to in modern tech, but is a variable reluctance unit plugged into an analog circuit of the tach. Meaning the change in current/voltage on the sensor is proportional to the tach's arrow climb.
I'm just planning on installing a tach in my 62 with 2h and currently only researching for options of how to replace this sensor with something much less expensive, keeping the stoch tach itself.
If I figure it out I'll try not forgetting to post about it, gonna take long though since I don't even have a stock tach yet.
P.S.: guys from Russia have had some success in installing a tach from 24V KAMAZ trucks, but these things pick up the rev reading from one pole on an alternator so they did have to get access to one of the terminals on a diode rectifier bridge. It's kind of a cheap-o rout back there for those who wouldn't spend 300$ on something that's just a frkn coil buried in epoxy.

i should have one
Thanks, but I live in South Caucasus (shipping gonna be expensive) and already found and ordered one for about 80 bucks. Turbo version, with a hopefully working sensor.
In a couple of months after I finally get it I'll try the following:
– posting an electronic schematic of the tach itself, probably on github since forums have a nasty habit of not keeping old media
– measure the thread pitch and diameter on the sensor (didn't manage to find this info online anywhere)
– see if it's gonna work with the "universal" chinese diesel flywheel sensors. Imagine if these things have the same thread, lol
Cruiserparts.net has them. That is where I got mine
