Please fill out the following to ask a question. MAKE:International MODEL:40s YEAR:1995 MILES:??? ENGINE:durastar DT466 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?
