Roof clearance lights and fender strobe mod

[Metal.Dave]

Wanting to add a strobe mod to the roof clearance lights. Where is the easiest location to tap into the + wire? 

1- Pillar (driver or passenger?) would be looking for a violet/gray wire correct?

2- Or near the control module, I am guessing it goes to the K9 BCM in the driver footwell area same as headlight BCM? If so what color wire on what color connector?

 

I know I will have to add in some type of double throw switch to disconnect the OEM wire and close the circuit on the strobe. 

 

 

 

 

Also want to tap the fender marker lights into the same strobe module, those are pretty easy to find and access at each fender, but instead of running multiple wires to each one- wondering where can I find the central + wire to tap into? From my understanding it looks like each fender marker is independently fused?

Thanks in advance!

Just get a Z Flash or SpeedTurtle:

 

Easy Flash Module 3.0 — Speed Turtle Engineering 

 

WITHOUT Lighting Control Module on truck -  Z-Flash BCM Vehicle Flasher for GM (Chevrolet/GMC) Vehicles

 

WITH LCM - Z-Flash LCM Vehicle Flasher for GM (Chevrolet/GMC) Vehicles

 

No cutting, tapping, splicing, overloading circuits, etc.  Just need to verify if your truck has the lighting control module present or not.  It won't flash the markers because those are supposed to be solid at all times for vehicle clearance rules.

I did see a flash module from some brand advertising on insta, from what I remember the price was around $500 so I gave it a fat pass. Its one of those things I might use a few times a year so not worth the price for me, but seems easy enough to tap into a few wires and make a DIY flasher while im at it doing the LED bar and aux lighting.
