Pick a color wire for the sending unit wire and connect it to the gauge using a ring connector.
Attach the other end of the same color wire to the Mustang Brown plug #8 (Oil pressure feed).
Oil Temperature Gauge
There are many ways to mount the oil temperature sending unit. Use a “T” junction and put it inline
somewhere in either of the hoses that run to the remote oil filter. Use an adapter to thread into the oil
filter relocater on the block. The harder way is to drain the oil from the engine. Remove the oil level
sender with a 1” wrench from the driver side of the oil pan. Drill out the sending unit with a
5
/
16
” drill.
Tap the remaining piece with a ⅜” x 18 NPT pipe tap just enough for the short end of the adapter to
attach. Wrap the adapter with Teflon tape and attach the adapter (short section pointed in) to the tapped
piece with the ¾” wrench. Attach the adapter and piece to the oil pan. Run the 8’ blue wire from the
gauge through the dash and firewall and attach to the adapter to ensure proper operation. DON’T
FORGET TO REFILL THE ENGINE WITH OIL. Note: a machine/tool shop can do the above drill
and tap for about $25 is you don’t have the tools. Attach the long blue wire to the sender and run it
through the hole under the 2” x 2” crossmember on the inside drivers’ wall. Run the wire to the signal
input on the gauge. Attach ignition power and ground wires to the blocks and the backside of the gauge.
Remove one of the plugs in the back of the driver head using a
5
/
16
” hex key.
Attach the oil temperature sending unit.
Run a new wire from the gauge to the sending unit.
Tachometer
Twist the Tach ground wire and the Tach light ground wires together, insert them into the same side of
the Blue butt connector and crimp.
Attach the black wire to the other end of the Blue butt connector.
Connect the positive wires using a red connector.
Pick a color wire for the sending unit wire and connect it to the gauge using a red connector.
Attach the other end of the same color wire to the Mustang gray plug pin #11 (SW to Ign. Coil (-).
Volt Gauge
Attach the ground ring connector and positive wire using a ring connector to the gauge.
Speedometer
Twist the Speedo ground wire and the Speedo light ground wires together, insert them into the same side
of the Blue connector and crimp.
Attach the black wire to the other end of the Blue butt connector.
Connect the positive wires using a red connector.
Use one of the wires that was run over to the computer and connect the wire to the wire in pin #3,
(Vehicle Speed Sensor, +) using a TAP connector.
Connect the other end of the wire to the Speedometer.
Fuel Level Gauge
Attach the ground ring connector and positive wire using a ring connector to the gauge.
