i would like to use B5 for map switching.

i press the AC switch several times, but on log DONT shows that AC is on,

what i'm doing wrong ? do i need to wire something ?

 

led#1 brake switch
led#2 ignition cut active
led#3 AC clutch
led#4 AC switch

 

This may be a dumb question but Does the fan speed have to be running?
Like normally the a.c. button won't light up unless the fan is turned on. Idk if it matters or not.

 

on 0:34 seconds you can see blower speed 3 and blue light on AC switch

 

if you have removed AC Im pretty sure you have to do a difficult work around... I looked into using ac switch but since I removed ac components mainly compressor you had to do a very tedious difficult wiring..

much easier to just find another input

 

i did not remove the AC ...

do you use neptuneRTP ?

 

No. I use ectune. But these inputs are the same across all platforms

 

and your ectune log shows when your AC is activate ?

 

No I don't have ac. So it can't complete the circuit. And send ground to b5 with that dash switch. However. It did before ac was removed.
