Hi Ihave problem whit tach learning. It's a chevy full size 1990 diesel. I don't have any tach so I have connected the wire to +12 v.

When I start the car and press the valet switch to to learn the signal it's not light in the LED

Thanks Ken

You are not going to be able to learn tach on a DC 12V signal. Tach is a fluctuating AC signal that increases as the vehicles RPMs increase.
Use the Tach wire as indicated below or change the unit to use voltage sensing.

You might also want to progarm your remote start to wait before start to allow for your glow plug to have affect.
