A buddy of mine have found a very good source for the connectors.

For the digidash you will need the female 090 MT connectors.
partnumbers:
12pin: #12P090-MT Female; 18pin: #18P090-MT Female; 20pin: #20P090-MT Female

I have bought a set and they fit perfectly.

I have a question regarding the external speed signal generator that the speedo cable connects to.
Can this be directly connected to the standard ECU or does the digital dash modify the signal before sending to the ECU
I need to feed a speed signal to a standard ECU to keep the auto trans ecu happy but there won't be a standard dash to supply the signal. The digi dash external speed signal generator looked like a promising solution

Unfortunately, the digital dash does mess with the signal some before it goes to the ECU. I believe it is something like a divide by 5 setup or something along those lines. The external speed sensor puts out 20 pulses per revolution but if I remember correctly, the stock speed sensor is something like 4 pulses per revolution.

Sorry, I haven't been around here in awhile. Yes there is. I go through the procedures on post #57. I am working on another LHD digidash, but without owning a Supra anymore, it is kind of difficult to experiment around like I did on the genesis project.

If anybody else does this or has a digi-dash that they are converting over to mph let me know, I have 3D printed speedo wheels from AutoExtrude that convert the actual input and make the speedometer accurate

Hey everyone, I'm back for a bit. Yeah, it's been years, but anyway, I haven't really done any more work after the first successful swap. I will try and answer whatever questions you all have. I saved the pictures and such to one of my drives a few laptops ago, so I will need to dig it out and such. The most valuable part of the whole swap was the translated JDM digidash wiring diagram. Everything else you can kind of figure out as you go along. What would be a huge help (something that didn't really exist much 8 years ago) would be a 3D printer big enough to print out a LHD gauge cluster shell. If someone made that and a swappable wiring harness, that would make the swap much easier.
