holden v6 speedo wiring.

[Ryan85nz]

Hey everyone

I have a cf bedford van with a holden v6 auto in it. think its out of a vp or vn commodore. I have put in a aftermarket autogauge speedo in and cant seem to get it to go. the lights and everything work on it.
From the gearbox sender I have a purple and white wire which I have wired up to the speedo sensor wire. A pnk and blue wire which I have wired up to a ac power. and a black and white which I have wired up to earth on one of the gearbox sump wire.
When i start the van the speedo goes to a 100kphper hour then back to 0but when im driving it dosnt go off zero.
can anyone help?

cheers
Ryan

hi rhino- I think you need the purple wire that goes from the ECU to the speedo head, not the purple wire from the gearbox transducer to the ECU??
