Ive bought a vdo programmable speedometer and I can't get it to read either an induction signal or a 2 wire hall effect. Ive tried running the hall effect though a gm relay 09.185.826 as someone has said thats what I need but still no luck. Anyone had any issues like this before? The person ive spoke to thats got it working through the relay has 2 inputs into his speedo pins 7 & 8 but there's only 1 output from the relay so I'm lost.

What engine and what ignition system setup?
Engine is an m52tu but its in my tube chassis pickup. Its running BMW suspension all round. Its running the standard ignition. I believe originally the abs sensors are fed into the abs unit which turns it into a canbus signal for the dash.
Many BMW ABS sensors are active sensors, you will need some external conditioning to make it compatible with your speedo.

I was told that the gm relay was a wave conditioner and would turn it to a pulse signal but it didnt seem to work do they have to be wired the right way round?
