Yes. But check the part number on it first, it may actually be the same part anyway. If you have to change the harness a lot then it is not worth it, you could do more harm than good. You will need the charging circuit diagram from both models to do it properly.

SOURCE: oil drain plug

It is located on the right side just under the oil tank ; if you follow the rudder hose that exits the rear right side of your oil tank it leads to the bottom of the frame under this is the oil plug. This hose has a plug clamped to the end of it or stuck into a prug that is welded to the frame.
After this unclamp and pull the plug to make sure that you have the dipstick out before pulling it loose.

Please do rate the solution as "FixYa" if found useful and revert for further assistance.
Thanks Rylee

Down and dirty way - take it to the dealer and have them install a new tire....

The hard way: place bike on bike jack and remove rear wheel by removing the axle nut and drifting the axle out of the wheel. Derail the belt/chain and drop the wheel out of the brake caliper. Remove valve stem to deflate the tire. Get a set of tire spoons and a 12 pack of COLD brew cause working with tire spoons is no FUN! Pry the bead loose with one spoon and the work your way around the wheel prying the tire beed to the outside of the wheel. Repeat this process for the back side of the tire (in the same direction as the first side so the tire will come off the wheel. Reverse and repeat to install new tire.

By now you will be loading your wheel into the truck and heading to the HD shop. It just really isn't worth the hastle to save the $25 or so to have this job done.

Align wheel with new tire on it with the brake caliper so that you have one shoe on each side of the rotor (you may have to actually remove the caliper if your pads are thick. Install your belt drive/chain drive and then lift the wheel to insert the axle through the swing arm, the chain tensioner and wheel. Reverse
on the other side. Place axle nut on axle and torque to about 80lbs.

Good to go.

To change the switch, first unplug the wires at the switch. Screw the old switch out and install the new switch into the tee connector. Do not depress either brake lever while the switch is out. Tighten the switch and reconnect the wires.

Usually you don't have to bleed any air out of the brake system but check the rear brakes for proper operaion. If the rear brake pedal goes too far down, bleed the brakes at the rear caliper. Make sure you don't run the rear brake master cylinder dry while bleeding the rear brake. Use only the approved type of brake fluid, do not mix the different types of fluid. Make sure the rear brakes are working properly before riding the bike.

How to replace voltage regular on 2007 softail Harley.

VOLTAGE REGULATOR Removal/Installation
Disconnect the negative battery cable
Remove the rear fender inner panel raising the back wheel off the ground, remove the 2 bolts securing it at the bottom, push it up to release it as it clips over a locating tab
Disconnect the voltage regulator lead from the silver post on the main circuit breaker.
Prior to removing the voltage regulator wires, note the routing of the wires through the frame. Note the location of cable straps and tie wraps. The wires must be rerouted in the same path.
After disconnecting any straps, leave them in place on the frame as a reference for installation of the wiring.
Disconnect the voltage regulator electrical connector from the alternator stator.
On 2001-on models, Remove the two bolts securing the voltage regulator to the mounting bracket.
Remove the screw and disconnect the ground strap from the mounting bracket. Unhook the wire retainer from the mounting bracket.
Remove the voltage regulator and related wiring from the frame.
Install by reversing these removal steps. Note the following:

Have a 99 heritage softail. Why does my right signal light start blinking ,on its own.

Hi Bill_mtz, probally because it wants too. No seriously you have either a faulty TS button/switch or a worn wire between the switch and the TS module or a corrupted connection at the wiring harness connector to the TS module or the module itself could be going south.

My passing lamps and headlights keep burning out and now this morning my headlight and passing lamps are out all together. Does anyone know what is causing this on my 2005 Heritage Softail Classic? I...

Hi Tony, obviously there is a problem in your light circuit. For your lights to keep burning out you have either to much voltage/amperage getting to them or a loose or broken ground in that front light circuit. I would first do a charging system test at the battery, voltage at 3000 RPM'S should be 14.3 to 14.7 volts anything higher replace the voltage regulator and make sure it has a tight clean ground. Other than that you will have to check all your wiring and connections from the ignition switch to the passing lamp switch and the high/low beam switch for worn or chaffed wires and corroded, broken or loose pins.

I have a 2006 harley softail fxstbi nighttrain. I relpaced the stator and the voltage regulater. After doing so the stator plug came undone mixing up the wiring order in the stator plug where it connects...

I'm sorry but I don't have a wiring diagram for that model bike. If the plug only has two wires in it, it makes no difference which goes where because the output of the alternator is an AC current and as such, has no polarity. This is the input to the regulator which rectifies the current into a DC current and then regulates it to between 14.5 and 15.0 volts. The larger diameter wire coming from the voltage regulator goes to the positive side of the battery either directly or indirectly through a circuit breaker or the positive battery cable.

Good Luck

I cant find a wire schematic for a harley davidson harness. the part # is 70482-07

The wiring schematic is part of the factory service manual. Harley-Davidson is very protective of their copyrighted material. You'll have to purchase a manual or find someone that has a manual to get the schematic.

Good luck

Connecting wire from regulator

The large wire from the voltage regulator goes to the Positive side of the battery. As an alternative, you can also connect it to the starter where the large cable comes from the battery positive terminal to the starter. I think that's where most Softail models have the regulator wire connected.

If you connect it to the starter, all this does it make it a bit easier to connect since the battery is inside the horseshoe type oil tank. Basically, you are using the battery cable as an extension cord to the battery to keep from having to fish the wire up to the battery.
