DESCRIBE ISSUE....

Need to safety one of these hydro line trucks. I have to safety two of these line trucks but one has no flashers, no hazards, no brake lights. Running lights ok, but 8 burnt, but at least I know series circuit is good.

I am assuming they are all on the same relay or module but I have no wiring schematics for heavy trucks and google sucks as all I fond are for RV or flat bed. Does anyone have a stock wiring of this or have experience with this flasher/hazard/brake light system?

Can any one help me out?

Of note, when I put on flasher for each side, solid high volt for each side, when I put hazards on, solid high volt for both sides. So flash relay not working, but current is going to bulbs, hence circuit path is good if not nothing would light up at all. Where is the flasher relay located?

There is a whole bunch of crap located around all that section and nothing is identified. So I want to go from scratch and just redo it like from Oem. That way I know when I stamp my tech # and safety this rig it won't come bite me in the arse.
