Install oil temperature gauge following the instructions in the bracket kit.

Fit perimeter groove in rubber isolation gasket (7) to inside edge of bracket, and tab of isolation gasket to square cutout in bracket.

Rotate oil temperature gauge (8) to align the face legend horizontal to the rider and push in the gauge. The locating tab on gauge will align with locating notch in gasket.

See Figure 17. Route wire harness conduit (10) along frame backbone and up through upper triple clamp to bracket. 2007-later Road King models: Route signal leads back towards front of vehicle and down left frame downtube. Secure with cable straps. Any excess wire harness should be coiled and secured under fuel tank with cable straps.

Locate the ground terminal and route the black ground lead to the ground location for the model motorcycle. Refer to Service Manual for instructions. 2004-later Softail: See Figure 7. On the frame strap (1) under the seat directly in front of the battery. 2000-2003 Softail: Top of the frame under the seat toward the front. 2004-later Dyna: See Figure 8. At either of the rear ground studs (1,2) under the fuse block. 2000-2003 Dyna: On top of the frame under the seat toward the tank. 2004-later FLHR/I: See Figure 9. Under seat directly in front of battery (1). 2000-2003 FLHR/I: In the well underneath the seat under the circuit breaker. 2000-2003 XL: The wire harness ground screws can be in several locations including under the seat at the junction of the frame backbone and the extensions for the shock mounts, on the left side of the frame under the tank, or on the left side of frame near the swing arm. 2004-later XL: On the backside of the primary case at the rear of the engine.

Route the orange/white power lead lead underneath and down a rear frame rail to the power location for the year and model. 2004-later Softails: The fuse block under the seat behind the battery will be fitted with an adapter to the fuse socket labeled P&A IGN to provide a main harness power lead. 2000-2003 Softails: Locate the orange/white power lead in the tail lamp harness pin connector (7A) under the seat behind the right rear corner of the battery. 2004-later Dyna: The fuse block inside the left side cover will be fitted with an adapter to the fuse socket labeled OPEN to provide a main harness power lead. 1999-2003 Dyna: Locate the orange/white power lead in the tail lamp harness pin connector (7A) under the seat. 2004-later FLHR: The fuse block will be fitted with an adapter to the fuse socket labeled P&A IGN to provide a main harness orange/white power lead. 1999-2003 FLHR: A main harness orange/white power lead inside the right side cover near the top. 2004-later XL: Behind the left side cover, locate the orange/white power lead from the main harness to the diagnostic pin connector (91A). 2000-2003 XL: See Figure 10. A main harness orange/white power lead (1) inside the side cover or under the seat to power the gauge.

Route oil temperature signal leads and connector down along frame downtube to oil temperature sending unit.

Verify the position and length of the wire harness and the wire leads to the sending unit, the power source and to the ground.

Bundle the oil temperature harness to the main wiring harness and any additional gauge harness along frame backbone by using cable straps (12) to support wires so they do not chafe or contact hot or moving points.

Slide the segment of high temperature tubing (16) over the connector and mate the sealed connector on the end of the oil temperature lead to the sending unit. Dyna and 2006-earlier Touring: With the new kit installed, the right side oil line cover will not fit and can be left off the motorcycle.

When the correct length of ground wire has been established, cut the harness ground wire as necessary.

Strip 3/8 in. of insulation from end of ground wire.

1999-2003 Dyna: See Figure 17. Crimp 5/16 in. ring terminal (2) to ground wire. All other Dyna models: See Figure 17. Crimp 1/4 in. ring terminal (3) to ground wire.

Remove ground wire fastener and add ring terminal to stud.

Install ground fastener and tighten to the torque specification found in the Service Manual.

When the correct length of orange/white power lead from the gauge to the main harness or fuse block adapter lead has been established, cut the lead as necessary.

Strip 3/8 in. of insulation from ends of the orange/white leads (including if required, the fuse block adapter lead).

See Figure 13. Identify splice configuration required (1, 2, or 3).

See Figure 17. Insert the leads and crimp the metal insert of the butt splice (1).

Using the Ultra-Torch or other suitable radiant heating device, heat the crimped splice from the center of the crimp out to each end until the sealant exudes out both ends of the connector (3) and the tubing assumes a smooth cylindrical appearance.

With the wire harness along frame and to the gauge, bounce motorcycle to look for pinch points between suspension components and gauge wires.

Cable wrap the gauge harness wires together at the back of the gauge housings.

To look for pinch points in the steering, turn front forks lock to lock.

Verify absence of pinch points or clearance from heat sources along wiring harness.

To test oil temperature gauge, turn ignition to ON. Gauge should illuminate and read ambient temperature or remain pegged at the lowest graduation.

Start engine. With engine running, oil temperature should rise as engine warms and should read approximately 230° F at operating temperature.
