Alternator question (new)
There is a plug on the back of my alternator (stock S4 alt). It plugs into the alternator housing and its a 2 wire plug attaching to the main wire harness. What does this do?
Thanks
Thanks

Ok, since nobody answered, I looked it up in the wiring diagrams in the FSM. It looks like that little plug connects the alternator to the alternator warning relay in the ECU.
If anyone has evidence to dispute this, please speak up.

Thanks NZ. So I can unplug this, install the haltech harness, and the alternator will function properly without that little plug right?

You've got a s4? The only thing you'll need to take care of is the Alternator Wires - you'll need to cut them out of your S4 Harness and rerun them. It's pretty intuitive once you get the Harness split open. In the S5, the charging Harness, as it's called, is integrated into the Front Engine Harness (driver's side harness).

Why are you messing with the plug for?  I believe that plug goes into the power harness which is separate from the engine harness?

that plug is very important for proper operation of the charging system.
For more info on alternators,
check:

that's a Triumph page but all alternators work the same.
