Do not continue with this step unless each Extension Cable has been marked as previously described.
Starting from under the instrument panel, route the 16-pin circular connector wire harness up to the instru-
ment mounting location. (See the wiring diagram at the back of this manual). Place the circular connector
about 9 inches back from the panel. Tie wrap the harness in place approximately 1 foot back from the
circular connector. This will allow the harness to be flexible and accommodate varying lengths in instrument
wires. Be sure these wires do not obstruct the freedom of travel of any controls.

Starting from under the instrument panel, route each Extension Cable to its appropriate probe. If new con-
nectors are to be installed on the ends of the cables, you may want to pull any excess cable length through the
fire wall and cut it off at this time. However, it is recommended you leave some extra wire length under the
instrument panel in case you choose to move the UBG to a different location at a later date. Varying cable
lengths will not affect the accuracy of this instrument. The Extension Cables and Probe Wires are
made of type K thermocouple wire that must not be substituted or extended with regular copper wire. Also, it
is important these wires not be kinked (i.e., do not bend the wires on a radius less than 1 inch).
Attach the appropriate connectors to the ends of each of the Extension Cables as described below:
Red Slip-on Connectors
A. Strip the over braid back 3 1/2". Be careful not to nick the wires.
B. Shrink a piece of 1" heat shrink over the cut portion of the over braid.
C. Split the two wires back 3". Be careful not to nick the wires.
D. Strip each wire and double the wires over. These wires must be doubled over.
E. Place a male connector on the red wire and a female connector on the yellow wire. Double crimp these
connectors. A good crimp is very important. Poor crimps will cause jumpy readings and are the biggest
source of problems.
Double the
wires.
Double Crimp Keep the tab straight.
