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.

Tach signal wire

The tach wire will be a pink wire under the wire loom leading up to your speedo. It's usually tucked into the conduit. If you don't have it there, then you'll have to run one all the way to the ECM.

Alternator wire diagram

I'm afraid not. The alternators as well as the trucks are wired differently.
The black yellow wire on both models goes to the fuse box, but on the 2005 model with the extra wire, the gray orange and brown white wires goe to the engine computer which acts as the voltage regulator. The 2003 computer would not have provisions for those circuits.

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).
