Hotwire Schematic

My copy of the Hotwire schematic is rather difficult to read so I've re-drawn it.

It's a CAD file, so if anyone would like a copy in DXF (or a PDF) PM me with email address and I'll send it.

Thanks Dave - I'll just grab the JPG for reference.

Chris.

Chris.

Obviously if anyone spots any errors let me know.

It might be handy as a DXF if anyone wants to modify it to a different version, etc.

Has anyone got a copy of the earlier Hotwire schematic? Extensive Googling only seems to give the one I've given above.

Thanks Eliot. I did wonder if there was one without lambda sensors - or are they simply omitted on early UK vehicles?

None of the UK hotwires had lambda sensors IIRC.
Probably just the North America tunes via the tune resistor ?

I've found one for a UK Disco without lambda sensors.

One gotcha is it seems to omit the series resistor between coil and ECU.
