Awesome, guys. Really appreciate the research that went into this.
Quick question: what do you recommend using to seal the junction between the speed sensor and the gear box? Is that RTV I see in some of the pictures?
I have mine and am planning to install tomorrow before heading to SAS in Ouray, CO this weekend!

Just a note, speed sensor has survived 3 years and over 20K miles. New photo shows minor oil seepage, red RTV silicone looks OK.
Can anyone please confirm this works on a 1991 - HDJ81?
anyone has the cable that joins this sensor jack to the main factory harness? mines missing.. seems that's why cruise
control never worked lol
or is it that the wire that is attached to the speedo sensor plugs directly into harness? i just found it draped over transfer case and not plugged into anything

Here's a link to another thread with photos FWIW

Please identify this Speed Sensor
I'm stumped trying to identify the speed sensor on my FJ80. This one is broken and I need to replace it but can't find an easy replacement now that Downey is gone. I need suggestions on where to find/make a replacement. It would go a long way if I could identify this one... Here are the...

nevermind, i found the jack ontop the tranny and plugged it back in. now to check if cruise control works
I have never used my cruise control 7 yrs of ownership. I am pretty sure it isn't working to begin with nor interested in fixing ..yes, it's an aussie company, those pictures are from my 91 fj80. my cruise works perfect!
Hello sirs, I hope your cruise controls are all working well still and you never had to think about this again... however if you happen to spot this thread, I would appreciate some help with identifying what I would be plugging the sensor into. First the ground work:
1990 HDJ80R 1HDT Auto VX (Aus). I've in years past done all the cruise control diagnostics and determined it had no speed input (no change in flashing lights between sub 30km/h and above).
Motor and servos were tested working on a bench.
Seems that at some point the speedo cable was replaced with one that doesn't have the sensor at all... a thing I only recently became properly aware of.
As all of you would have done, I checked for the part number and find it discontinued, then stumble on this gem of a replacement option, YESS!!
Like a few others though, I'm struggling to find where I'm going to plug it into.
I can locate the 'transmission wire' as I believe it's known, and can see that at some point that was modified, and high up on top of tranny I found a loose triangular plug, which I think has a blank making it 3 wires despite being 4 pin connector.
Seems like everyone's plug location is different in this thread, but wondering if anyone can give me at least a semi confident 'yea that would be it'.
Then the challenge will be reaching up there to snip off the plug and either splice or installer new plug... really isn't much room to get up that high :\
Photos:
1. Speedo cable output with a converter to account for 35" wheels
2. 'Transmission Wire' most easily viewable and closest to the speedo output. Can see the broken wire and the splice-around.
3&4. 2 views of the loose plug I see tucked away further up on the tranny. On the complete opposite side to where the speedo output is - hence not sure if this is what I'm after or just some random loose thing that is perhaps made redundant by some modified transmission wire harness.
Bonus points: If anyone can tell me what that triangle connector is, I can just plug a new male connector on to it and run as much extension as I need... It looks like it's probably this?: 3 Pin Toyota Crank Angle Sensor - https://www.efihardware.com/products/3085/3-pin-toyota-crank-angle-sensor so I would need the matching male
Thank you!

cruise control trouble
While driving to work this morning I set the cruise and was putting along fine. I then hit a bump on the freeway (large bump), and the cruise just shut off and wouldn't come back on. Any ideas? 92 FJ80
