Vehicle speed sensor buffer.
Posted: Tue Dec 03, 2013 11:09 am
Making up a new loom for my hotwire EFI system and I want to use the speed sensor input to pin 6 of the ECM. Reading up about this input I see that the generated voltage pulses from the sensor are sent to a buffer within the speedo.
I have a new speed sensor but not the speedo buffer, what is this buffer?
Can I make one up?
Presumably I cannot send the output directly to pin 6?
Can anyone offer any help/advice please.
Thanks.
Andy.
