Decided to fit my UK clocks today as the JAP ones have about had it and not accurate at all speed wise. But I cannot see any converter as such to change it back to a clean signal so with the new UK clocks fitted im still getting an incorrect reading. Pictures attached show what I'm dealing with, theres a thin yellow wire with green strip that had been taped up but appears just to be soldered back together nothing inline and a fatter green with yellow strip has a bullet type connector in line but nothing in it no resistor or anything, then thers random brown white and red cables going down behind the dash but can't see where they go to.

 

I'm not sure which is the speedo signal to trace back

 

Sorry for the big pictures but it makes it clearer.

 

 

Crikey mate looks like someone has been busy in there! I thought the green and yellow one with the bullet connector was the speed signal as this is the one you can disconnect to make the bonger stop going off at 70? although I am happy to be corrected.

right further investigation seem that the wires lead to a little box, brown white and black from the left hand connector and a red one from the right hand connector( this one just taps off the green one rather than replaces) I'm thinking if I undo the tape on the left hand side connector and reconnector the wires that lead off to the converter all should be good as original?

sorted in the end just a case of connecting the original wires back and pulling the dodgy looking box out.

Nice one mate is the dodgy box the black one in the background? If yes its the bonger.

No mate the wires went down to a small silver box with a circuit board in it that was stuck under the heater pipe under the steering column, had to strip some more to get to it. It had obviously gone wrong somewhere and also my jap spec speedo was very intermittant probably a dry joint that can be fixed no doubt. Just nice to know what speed i'm going now :hyper: seems pretty accurate too when compared to GPS speed reading on my sat nav.

Pleased for you mate. Little things like that annoy the crap out of me. Really awesome when you fix them.
