On a one wire alternator, the one wire is your 12V (nominal). So anywhere that wire goes should be 12V.

More than one resistor
You will need one resistor per analog input. The location of the resistor shouldn't be that important.
The way you've drawn your circuit, all of the analog inputs will be shorted together.

Alternator Warning Lamp
So what you need is a pullup resistor on the W/R wire. It is my understanding that the alternator needs current flowing into the L terminal to get going. You will want a resistor equivalent to the the lamp resistance. Be careful of the wattage rating of the resistor. The 7.5A fuse (#25) implies a bi...

More information needed
I'm not exactly sure of the wiring changes you made. Did you just connect the alternator to the Dash 2, is the alternator still connected to the light and is the light still connected through the fuse to a 12V source?

Pull Up Resistor
Assuming that there isn't anything else to the tachometer output. All you need is a pull up resistor to either 5V or 12V. The value depends on the tachometer output capability and the input current requirements of the dash 2. Unfortunately I don't know either of these.

Confused?
Well I read both of the previous posts and I have to agree with both Dan and Midlana. My number is only correct if you are looking at the coil or the HT lead to the center of the distributor and I'm wrong if you are looking at a single spark plug lead. So I then went to my vehicle settings in analys...

A little more information
There are three potential issues. First as Support mentioned above, the minimum pulse width. You have calculated 0.86 mS. According to the knowledge base, you only need 0.25mS. So this should be okay. The other issue is how these sensors work. As you move the sensor closer/farther from the bolt head...

Two Pulses per Revolution
A Ford 1600 crossflow is a 4 stroke, 4 cylinder engine. So four ignition events (one per cylinder) in two revolutions (which is 4 strokes), which means 2 ignition pulses per revolution.

Another possibility?
Is it possible to use a user variable to control the shift lights?
If so you should be able to create a math channel that will activate the lights when either water temp is high or the oil pressure is low.

Redundant
Installing both a gas pedal position sensor and a throttle position sensor seems redundant. Under normal operation as you move the gas pedal the throttle should move a proportional amount. The only time they will move differently is if there is a problem with the throttle cable.

12V Regulators
Micrel makes a MIC29151-12WT. It is a 12V linear regulator that supports 0.35V of dropout (Vin to Vout) and 1.5A of output current in to TO-220 package. I've never used this part, so I have no first hand experience with it. I have used other LDO (0.5V) regulators extensively with no issues in non-au...

Which way is Plus/Minus
The DL1 by default expects forward acceleration to be in the direction from the DL1 front panel to the DL1 back panel. It can be configured to work the opposite way. The installation orientation setting is part of the configuration for the DL1.

Installation
Using the "schematic" on the top right of that PDF, you would replace the load with a 1K ohm 1/4 watt pull-up resistor and connect the black wire to a digital/frequency input on the DL2

Dash 1?
Do you really want to mount your dash in the center console as opposed to somewhere you can easily see it while driving? Or do you mean a DL-1? A DL-1 will definitely fit there.

Choice
Not knowing the circuit it is going in, makes an intelligent decision impossible. So if 1W was what you wanted but can't find, then you should go to 2W and have some margin. Perhaps you can give us more information to help you make a better decision.
