I would think the speed signal wire will be in the same pin out on the multi plug as any other GTT as i don't think the tommy kaira would have a special harness. All you will need is a CK-UN-09 speed control unit wiring diagram from import solutions to find which the pin out is at the back of the speedo head

Locate the lefthand, brown 20 pin plug and on the left hand row, 2nd from bottom, Orange wire that should be the speed sensor wire

www.importsolutions.co.uk give them a call ask for Steve he should be able to fax you a copy. I take it your speedo has been converted to read in MPH? if so it could be the speed conversion unit that's at fault as it sits in-line on the speed sensor wire and changes the signal to read in MPH

First thing i would do is remove the speed conversion chip (should look like a small black box with 4 wires 1+ 1- and 2 in-line with the speed signal) and return to standard and if the speedo starts to work again then it's your conversion chip

I also have one of these.

Any idea if it can be fitted?

And will the digital speedo work if you simply hook it up to the existing speedo wire in the car?

Finally, do the shift up and max torque lights work properly?
