How to install a S&S speedometer calibrator to a six speed Harley Davidson.

Hi all.

In this post I will walk you through the steps need to install the S&S speedometer calibrator to the six speed Harley speedometer system.
Currently, there is no calibrator available for the Harley six speed. this is because Harley changed the speed senor for the six speed transmission. It works the same, a three wire hall effects generator, but instead of having a three wire lead to a harness plug, the new sensor has the harness plug into the senor itself.
The five speed unit used a unique triangle male/female three prog plug, the newer one uses a Delphi/GM style one.

I talked with the engineers at S&S as to if these older unit would work on my 2007 six speed. They said it would work just fine but I would need to cut into the harness and wire in the older style plug in for it to work.
I ordered all the parts needed for this from my local Harley dealer, and they are readily available.
You will need to order the both plug shells, then plug pins and the lock clips.

Along with these parts you will need three feet of red, white and black 14 gauge wire, 6 crimp connectors, heat shrink, wire loom, electrical tape, wire ties and the proper crimping pliers.

Ok, lets get started.
I am using my 2007 Electra glide, but all these systems work the same, your bike may vary in routing, but it is the same sensor.
1) Remove the covers, bags and seat.


2) Remove the battery.

3) Next identify the speed sensor wires, it's under the starter, and you can see it by looking down the drive belt.

4) Trace the wires up to the loom.

5) Now carefully split the sheathing to get to the wires. DO NOT REMOVE IT, split it enough to work on, but tyou will need to reinstall it later.
Once you fine the four three wires (They are white w/green, Red w/white and Black w/green) In my case, the wiring schematic showed that the white w/green splits and one goes to the speedometer, and one to the ECM. They both start at the same place and have the same signal, treat them as they are, the same wire.
Now is the time we cut the harness ties loose so we can work.

6) Now that we have the harness loosed, and we have traced the wires to the loom, we need to gain access, carefully split the covering to get to the wires. DO NOT REMOVE THIS COVER it wiull need to be resecured later on.

7) On my bike, the white w/green wire is the signal wire (Black w/green is senor ground and the red w/white is the 5 volt power wire) is split just after it leaves the sensor, one wire goes to the ECM and other goes to the speedometer. You will need to put these two wire together to run them through the calibrator, it's OK, there are the same wire with the same signal, just treat them as one wire.
Now is the time to cut into the harness.


8) Strip the wire ends and then we will turn our attention to building the new harness's.
You will need to use this wiring for the plug ends.
yes, it's crude, it is made to be that way so Harley doesn't sue me for copyright.

You will need one of these crimping pliers, I got this one at a NAPA store, if you do not have one, you will need to get one, it's the only way you can get the connector pins to fit in after you attach the wires.


9) Assemble the plugs like this.



Measure the length to where you are going to mount the calibrator. I found a good spot for mine on the left outside of the battery box just above the fuse box. I then cut the wires to length, and using the electrical tape, taped them together and covered them with the wire loom covering and installed them.
The Female connector goes towards the sensor, and the male goes towards the speedometer.

9) Now run the wires over to were you plan to install the calibrator, careful to avoid sharp corners and edges, then use wire ties to re cover the wire harness, and put all wires and covers back into the stock locations. Be sure to replace all the wire ties you cut off at the beginning, they were put there for a reason, and they need to be there still. make sure they is room for the battery to go back in place without pulling on any of the wiring. It's a tight fit in here, but if you plan it out right, it will fit just fine.

10) Now lets go on to the mounting of the calibrator unit. If you are going to use the spot I am, clean off any dirt or oil and with some double sided tape( I used emblem mounting tape from 3M.) connect the wires and attach the unit to the bike.


Use the calibrating information provided by S&S to pre-set the unit.
Leave the side cover off so you can adjust it on your test ride.
Now replace the battery and put the bike back together (Leaving the left side cover off for adjusting) andf get ready to ride.


Once you get it running, you will want to take it onto a freeway or area you can go 60MPH.
Use a stopwatch and the mile markers, hold you speed at 60MPH and as you pass the mile marker, start the stop watch. I suggest you go at least 10 miles, Ideally, You should read 10 minutes at the 10 mile marker. (60MPH is one mile a minute). Adjust as needed and start again.
Then you can use the Odometer check, again with the mile markers, as you pass one, reset one of your trip meters. Again, go at least 10 miles, Ideally, it should read 10 miles after 10 mile post.

When I checked mile, I calculated a speed error of -7. I covered the 10 miles @60MPH in 10:19.0 seconds. and the return trip, I showed 10.1 miles @ the tenth mile post.
That is a 1% error to the meter reading fast. Since ther S&S unit does 2% changes per unit, I will leave it be, better to read faster then you are really going, even if it's 1MPH, and it is a heck of a lot closer then it was before.
the gearing change I did (An Andrews 30 tooth drive pulley) is just about prefect for this bike, in the area I ride in and now my speedometer read correct.

One last thing you need to know. It's about the 6 speed light, It will no longer work after you install the calibrator.

Why?

The 6 speed light is controlled by the speedometer (TSSM) and there is no sensor telling it the bike is in 6th gear. It is a program inside the TSSM that compares the RPM to the speed signal, when it matches the programed parameters, it turns the light on.
Since the speed sensor signal has been changed, it no longer will match, so the TSSM thinks the bike is in 5th, not 6th.

As far as I know, to fix that you would need to change the TSSM program, and if you do that, it will void any and all warranties on the bike as it will be called tampering.

Have the bike run right and give you the correct speed reading, or have a useless silly light.

I chose the one to help me avoid speeding tickets.

I hope you have found this useful.
