Stop Tail Turn Wiring Question

[swhetsell]

I am in the process of replacing my stop/tail/turn lights, backup lights, and front marker/turn lights with LED bulbs. I intend of using these replacement bulbs as the standard function bulbs, but I need to place a after-market flasher unit inline to enable strobe functions on the bulbs. The after-market flasher has input for the stop/tail/turn signals from the vehicle to illuminate the bulbs as needed. I would like some help locating the best location to connect the vehicle wiring to the flasher. Each bulb for the marker lights must be isolated from the other three. I would be happy to try to clarify any questions about this setup. I have a 2005 explorer. Thanks in advance.

cant you just unplug stock flasher unit and plug in replacement ?

I've never replaced a flasher before. Where do i find the relays that are between the turn signal and brake switches and the actual bulbs?
