Electronics International SR-8A - Manual (Page 16)

Note 1: Any channel will accept any one of E.I.’s probes.
Note 2: For channels requiring Precision Connectors, you will remove the Slip-on Connectors and install the
yellow Precision Connector as described later in this installation procedure.
Note 3: The wire harnesses for a twin-engine aircraft will arrive with the red Slip-on Connectors removed.
The connectors are left off to facilitate installation. Slip-on Connectors are supplied in the accessory kit and
will be installed in a following step.
10. Route the Circular Connectors:
Do not continue with this step unless each Extension Cable has been marked as described in step 9.
Starting from under the instrument panel, route the Circular Connector up to the instrument mounting loca-
tion (see the Wiring Diagram at the back of this manual). Place the Circular Connectors 9 inches back from
the front panel. Tie wrap the harnesses in place approximately one foot back from the Circular Connector.
This will allow the harness to be flexible and accommodate varying lengths in instrument wires.
11. Route Each Extension Cable:
Starting from under the instrument panel, route each Extension Cable to its appropriate probe. If new
connectors 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 for later modifications. 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.
