B&M 80212 TRANS TEMPERATURE GAUGE - Manual (Page 2)

the coupler and TIGHTEN VERY LIGHTLY!
STEP 4. Run a length of wire from the temperature gauge
to the sender unit using the wire supplied with the kit. Bare
1/4" of the end of the wire supplied at the sender unit.
Install an eyelet terminal supplied with the kit on the end
of the wire and crimp it tightly. Install the terminal onto
the sender unit stud. Install nut on to the stud and tighten
securely. Be sure the connector/wire does not touch the
body of the sender. Secure the wire in position so it cannot
touch any hot engine components. Be sure that the base
of the sending unit is properly grounded. A sending unit
installed in a rubber cooling line is not properly grounded.
Improper grounding will cause a false reading. Install an-
other eyelet terminal at the gauge end of the temperature
wire. Remove the nut and lock washer from the negative
("-") stud on the temperature gauge (see Figure 3). Install
the terminal onto the stud and install lock washer and nut.
Tighten nut snugly. DO NOT OVER-TIGHTEN AS THIS
COULD DISTORT BRACKET OR DAMAGE GAUGE.
STEP 5. Run a length of wire from the temperature gauge
to the ignition switch or fuse block using the wire supplied
with the kit. Bare 1/4" of the end of the wire at the tem-
perature gauge. Install an eyelet terminal on the end of the
wire and crimp it tightly. Remove the nut and lock washer
from the positive ("+") stud on the temperature gauge (see
Figure 3). Install the terminal onto the stud and re-install
lock washer and nut.
Tighten nut snugly. DO NOT OVER-TIGHTEN AS THIS
COULD DISTORT BRACKET OR DAMAGE GAUGE.
Connect other end of wire to an accessory or ignition
circuit that is "hot" when the ignition key is on. DO NOT
ALLOW "HOT" WIRE TO TOUCH THE "-" STUD ON
THE TEMPERATURE GAUGE.
STEP 6. Run a ground wire from the "GND" stud to
chassis ground (frame or body). See figure 3. DO NOT
OVER-TIGHTEN AS THIS COULD DISTORT BRACKET
OR DAMAGE GAUGE.
STEP 7. Run a length of wire from the temperature gauge
to the dashboard instrument light wires or terminal board.
Bare 1/4" of the end of wire at the temperature gauge.
Install the female spade connector furnished and crimp
tightly. Slip connector onto gauge spade terminal (see
Figure 3). Secure all wires up out of the way from heat or
any moving parts to prevent damage.
STEP 8. Re-connect battery cable. Turn ignition key on.
Gauge will read oil temperature. Start engine and check
T-fitting for leaks. As transmission oil temperature warms
up, the gauge will indicate properly. Turn on lights to check
operation of illumination bulb.
