This has been a popular subject with a lot of wrong answers out there.  Installers were getting so mixed up that we just decided to put a truck together and install our gauges with a holley termantor X-Max to clear things up.

Turns out, this was relatively simple, now we can share all of this info with you to make you life easier.

The only difference between the Terminator and the Terminator X-Max is transmission control.  On the X-Max you will be picking up the speed signal from the X-Max itself, whereas on the Terminator the signal will come from the transmission sender itself or a GPS sender.

HOLLEY TERMINATOR INTEGRATION

The image above is a graphic representation of all installations regardless of vehicle or engine make, they all operate the same.

TACHOMETER:

Connect to the violet wire on gasoline tachometers. The Terminator has a tach signal wire (blue) that outputs an 8 cylinder signal.  Your NVU tachometer is pre-set in the proper configuration at 8 cylinders and the #5 DIP switch in the proper position as follows:

SPEEDOMETER:

You will be picking up the speed signal from a speed sender.  This can be one of 3 types:

• 2-wire OE:  One wire is ground, the other is signal.  It doesn't matter which one is which.  The signal must be dedicated to the speedometer and cannot be split.  Note on Tremec transmissions:  These output a very weak signal that may be difficult to read.  Don't worry, we have a great video on the subject HERE>>>.
• Cable replacement sender:  We have 2 styles, our 99001-04 GM/Chrysler style and 99006-04 Ford/tremec style.  These replace the cable from your mechanical speedometer pickup and work great.  these do not include a gear so you can re-use your existing gear or you may need to purchase one.

• GPS speed sender.  Don't want to mess around with all of that?  OK our ready-to run GPS speed sender part number 99010-04 is also a great option.

The final way to pick up your speed signal is if you are using a standalone transmission controller (automatic only).  Please contact your controller manufacturer for the following:

• Speed signal output wire/pin location
• Speed signal output (this is generally in pulses per mile)
• Speed signal type.  This is going to be a hall effect or AC Sinewave.

Once you have that information, all of the setup info is in our instruction big book.  Of course, if you need some help, we are more than happy too, but we will need those 3 pieces of information to give some solid advice.

WATER TEMPERATURE AND OIL PRESSURE:

All this needs is the senders.  You must use the NVU senders or the gauges will not operate properly.

Locations, thread sizes and such differ by engine type.  We have an excellent ARTICLE RIGHT HERE that shows sender installations on most popular engines.

VOLTS AND FUEL

VOLTS is internally monitored, and no additional wiring is required.

FUEL LEVEL is read from your fuel sender in the fuel tank.  Our Phoenix Platform gauges have fully programmable, dampened fuel gauges that can work on just about any tank/sender.  We have a comprehensive article on how to use, set-up and test fuel senders and gauges RIGHT HERE>>>>

TERMINATOR X-MAX INTEGRATION

This integration is exactly the same as the standard terminator, but now the speed signal will be coming from the X-Max itself.  While this isn't overly difficult, it does require setting up an output and changing some settings.  We have a really good video belos showing the process.  Check that out and in the event its too much for you, as long as your transmission is shifting properly, you can also just use an ADD-ON GPS sender.
