N12 Turbo Forums

hey guys,
Just wondering if the 2 wires coming off the gearbox are the speed sensor wires?? and if they are, am i able to put a digital speedometer on them??

If you are referring to the two wire switch on the passenger side, it is the reversing switch.
The N12 E15 has no speed sensor. You can screw a speed sensor into the speedo drive. It looks like it should take a generic digital sensor. I know a 7MGTE one should fit.

interesting to know, may try this to get my digi dash to work

there is a reed switch in the speedo cluster that generates a speed signal

As madn12 states, in the back of the speedo and a direct connection to the ECU!!

Please

Its a switch, it switches at 5mph to tell the ECU the car is moving.

Damo

its not a switch that switches on at 5, it pulses i think its 4 pulses per revolution it still works the same digital speedo the more pulses the more speed

If that is the case I am more than happy to be corrected, but I have never seen it called anything other than an on off, non pulsing switch.

thanks for the info guys, have an old magna here thats not being used any more, so might have a look at the speed sensor on there
