ECU plug wires

[99mx5]

Any diagrams for ECU plug wiring?

Im particularly interested in :
- TPS
- vehicle speed
- intake air temp

Ari,

The pinout is in the instructions section. Open the one for the 99. It shows the TPS at 3E. The IAT is at 2B. I am not sure the speed makes it's way back. I would think yes but the sender in the transmission comes in and goes direct to the small microcomputer in the dash. It then branches to the cruise control module. It could be 2D but I am not sure. If it is NOT 2D, it is not there at all.

Thanks Tom. I can plug in formulas to determine WHP and Tq in the innovate software and the speed will make the formula much more precise.

Hopefully the speed is an analog signal. It may be a digital signal?

Looks like you were right, W/B is pulsed VSS signal, fortunately the LM-2 can interpret pulsed signals.

Cool. I kind of thought it would not be analog. It is sent on to the cruise control and those controllers typically like to control to a digital signal as well.
