Power wheel wtd, or help to make info req.

[Stu.Pink]

Hi,
I have a phase4 ecu, with no power wheel so is running low boost mode, I havethe 3pin connector wire from an old phase3 kit that goes from the power board to outside the ecu with the big black connector (red/black/brown wires), so assuming that is the same I do not need that bit, but does anyone have a spare wheel they don't want?

Alternatively, can anyone tell me what resistance I need over which pins so that I can simply wire it up for full power constantly?

Thanks.

It's a voltage divider in 5 steps between 0 and 5V. You have a ground, a +5v supply and the signal to the powerwheel. Maybe someone can measure the voltages, but when signalwire is connected to the 5V you should have full power setting.

Thanks!! That is good enough for me.
So If i use a multimeter set to DC-V and measure against ground, I should find two 0v (the earth and the signal) and one at 5v.
If i then use the multimeter on ohms to check the resistance to earth of the two at 0v one should read 0ohms as it is ground and hopefully the other will be slightly higher?
So if i connect the 5v directly to the one that is a bit over 0ohms, and leave the other ground disconnected I will have full power?

I won't try this for a couple of days, in case anyone has anything to add.

Many thanks.

That should be right indeed.
