I have been trying to program the RPM learn on my autopage 850lcd remote alarm/starter. I have discovered I tapped into the oil pressure gauge and not the tach feed. I have a 90 XJ 4.0L
I have gone right to the coil and I find that the wire listed at the tach (green wire) delivers 13+ volts while the vehicle is running. This is the same at the tach gauge end. I have checked the Factory service Manual to confirm I have the right wire.
My problem is the alarm install manual says I should be getting between 1-6V not the 13v+ I’m getting.
Do I need to hook the tach wire to something else?
