How to wire a tach on 05 heritage softail

I took a tach off a 2003 standard softtail. The tach had 3 leads, black, red, and yellow. on the 03 softail the black lead went to black, the red to orange/white, and the yellow to pink. i am trying to put the tach on a 05 heritage softail and have the black to black, red to orange/white, but can't find a pink wire. with the black and red wire hooked up, the tach light works but i can't get the tach itself to work. which wire on the bike does the yellow tach lead go to?

Locate & route Black lead to ground / 2004-later softail: On the frame strap under the seat directly in front of the battery.

Locate & route the pink lead to Signal / For 2004 & later FXST/C/I The #3 cavity in the connector {39b} on the back of the speedometer. The socket terminal on the signal (pk) lead fits the #3 cavity.

Locate & route the Orange and white lead to power / Ummm.. it's saying for 2004 and later to adapt to the fuse block For earlier [ For 1996 to 2003 softail: locate the power lead (o/w) in the tail lamp pin connector {7a} under the seat behind the right rear corner of he battery.] "here you are looking to run it to a fused line, not directly to power/battery" I hope this helped.

Hi, David none of the above your bike did not come with a tach if you are trying to install a Harley combination speedo/tach accessory then there are installation instructions you can download along with most aftermarket tachs also for this scenario you will need your service/owners manual if you can not find the first and best tool you ever bought for your Harley, despair not, for a mere $5 you can download another one.

I am in the process of changing my turn signals.The turn signals that I have are 3 wires and the softtail only has 2 wires. The turn signals that I have to replace the existing ones have a black with white...

The turn signals you have bought are complete with running lights. This is mandatory in most American states. You only need to wire the Red and The Black leads to make the indicators work. (Unless you are in America).

Tech moved 5hp Jacuzzi submersible pump to new well and lost color code.(red,blk,yel) Can I measure resiastancde between wires from pump to determine color code to hook up to the controller?

Measure the resistance between the 3 leads:
Wire 1 to 2, wire 2 to 3, wire 3 to 1.
Find the highest reading. The lead not used in this highest reading is
the yellow lead.
Now use the yellow lead & measure to the other 2 wires.
The higher reading will be the red lead.
The lower reading will be the black lead.

All of a sudden there is no color just black and white on my 27pt6441

this sounds like there is a problem with the cables connected to the tv, Make sure they are all pushed in correctly and in the right place. For example if you have a yellow lead and it is in the red plug hole then this may cause a problem. Some tv's also don't need all of the leads plugged in (Red,Yellow, White)

Alternatively if you are using a scart lead, it will display black and white if it is not pushed in correctly.
