hey all

today i was doing some small finishes on my car and i got caught on my speedo setup,

i changed the speedo gear and put in the electronic speed sensor to suit the dash,
now i dont know where to plug that sensor into. we checked everywhere and cant find it, i would of thought it would of been where it connects the box loom to engine loom but im guessing that cause their not orignally eletronic so i might have to wire it straight into the dash loom some how?

cheers fellas

You'll have to run some wires up from the speed sencer to behind the glove box. The sencer has 3 wires, 12v, earth and signal. Connect the 12v to the IGN wire.

On the same plug with watertemp/tacho etc on the mz21 body loom there should be a purple with white stripe wire and a black with yellow stripe wire. Connect the speedo signal wire to the purple/white wire. Then connect the black/yellow wire to the earth.
