Hi
I have a 1JZ-GTE with oem electronics, and a transmission from a chevy colorado (Aisin MA-5, AR5, whatever you want to call it) which has a 2 wire vehicle speed sensor.
I was planning to get an adjustable electric speedometer, something like this:
http://www.amazon.com/Auto-Meter-3989-Programmable-Speedometer/dp/B00062Z6UG
However, I know the vehicle speed is usually transmitted electronically from the gauge cluster to the ECU, and that the ECU expects a speed input...
What are the chances I can hook the GM rear speed sensor up to that pin on the ECU?
Does it accept a "standard" signal of some number of pulses per mile, or would I need some kind of conversion circuitry?
Does the ECU require a speed signal to work right? What would be the effect of leaving it off?
If the sensor is the wrong number of pulses per mile compared to what the ECU expects, could that create a problem with early speed cut, or anything else along those lines?
Thanks for your help.
