Installing Cables
Two cables are supplied with the GPX Pro. Cable A and Cable B each have 6 wires.
1. Remove the 4 screws holding the back cover on the GPX Pro.
2. Flip the cover up as in the picture below. Be extremely careful when removing the back cover
as the Li-Ion battery is attached to the back cover.
3. Plug in the A cable for onboard vehicle battery power and DAQ inputs 1, 2, and 5 (digital RPM).
If you are using data channels 3 or 4, you will also need the B cable.
4. Route the cables as shown in the picture below. Cable B specifically has to route to miss the
mounting post circled.
5. Looking from the back -- cable A goes in the far right grommet hole, and cable B in the middle
one. The third grommet holes is used for the optional external antenna.
6. Make sure the grommets are oriented correctly, and near their final location
7. Flip the back cover over and fit the grommets to their holes.
8. Install the screws, being careful not to over-tighten them.e

Wiring with Scotchlok Connectors
Included with your GPX Pro is a set of Scotchlok connectors that can be pressed onto your wires
with no stripping or soldering required. Supplied initially are 6 of these connectors in order to
begin wiring your vehicle to collect data. More Scotchloks and color-coded wiring can be
purchased in our DAQ Wire Kits at www.xtracing.com. All wire used with Scotchlok connectors
must be 22-16 AWG. We have found that most vehicles use wiring within this range. Make sure
that the metal tab in each Scotchlok is pressed down firmly over both wires before you close the
Scotchlok. There should be no bowing of the cap when you try to close it. If your cap appears
bowed, then your Scotchlok is not fully engaged and your GPX may not record your data.
