I started installing my boost controller today, and it has an input for throttle position. Looking at the schematics, there are 2 different throttle position sensors on the TAC module. One is pin 1 (dark green wire) and the other is pin 11 (purple wire), both on C1 (tan plug). Will either of these work? The controller can be set up to read 0-5v or 5-0v.

TIA

 

They both go from 0 to 5V, but they are not the same. Use the green wire.

 

It will be this afternoon before I can get back out there, but I'll try that.

What is the difference between the 2?

Now, is there a way to make it read English units. Right now it shows km/hr for speed, mmHg for vacuum, and kg/cm2 for boost.

Thanks

 

The 2nd sensor circuit will not provide a continuos signal. It is used as rationality check.
