VR Speed Sensor Wiring

[MBS206]

The speedo won't work with headlights on...

I changed 12V+ acc pick up.
No help.
Earth is straight to the body, and I wired the signal wire into where you said.
The moment parkers or above comes on, the speedo dies. The dash just won't get signal, or won't deal with it anyway... :S

Anyhelp?

i would be changing you earth & 12+ again and checking the speedo purple/white connection. obviously there is a problem how you have wired it up and checking any connections that you have touched wiring it up, if you headlights worked ok before you wired up the speedo then the problem must be somewhere in the new wiring that you did.

so mate what u is saying pretty much if this sounds right is run the wire straight from the sender straight 2 the dash and bypass the ecu. sorry if l not understand what u mean l just dot the best when it comes 2 electrics.

yes it needs to bypass the ecu and be connected to the output side of the ECU to the speedo:yeah:

The headlights work GREAT!
It's the speedo that doesn't.

Driving along, in daylight, speedo working fine, turn the headlights on, and the speedo just goes back to zero! It's crazy!
I'm going to do some checking in my haynes manual, see what wires go near each other in regards to headlights and speedo...

By any chance, did you do anything with the "power" switch cables at all?

hay mate just wonderin about the reverse lights

I picked up a the "power" off my neutral start switch and reverse switch. ran it down to the reverse switch box, and ran the negative back up to the appropriate negative point on the neutral start switch.
That one was piss easy!
