on the 1st gens, it is right under the steering wheel......i turned on the turn signal with the car off, and felt around different relays until I felt the relay in my hand clicking.

Description

The BCM monitors inputs from the combination switch to determine when to activate the turn signals. The BCM outputs voltage direction to the left and right turn signals during turn signal operation or both during hazard warning operation. The BCM sends a turn signal indicator request to the combination meter via the CAN communication lines.

The BCM performs the fast flasher operation (fail-safe) if any bulb or harness of the turn signal lamp circuit is open.

Okay my question is can I put a flasher in my car like is there a flasher relay somewhere? To stop hyperflash

Your answer is:

The BCM monitors inputs from the combination switch to determine when to activate the turn signals. The BCM outputs voltage direction to the left and right turn signals during turn signal operation or both during hazard warning operation. The BCM sends a turn signal indicator request to the combination meter via the CAN communication lines.

Do you know what the BCM and CAN are?

No I don't I just need a simple answer yes or no I have aftermarket lights and hyperflash is an issue

Welcome to the new world of high tech automotive electronics. The simple answer is NO; there's no flasher like in the older generations of vehicles. Like Trock tried to explain to you, the steering column stalk switches send a signal to the BCM which in turn notifies the IPDM to supply power to the exterior lights. The IPDM is a complex sealed module. What you need to fix requires a fix from some aftermarket kit.
