Easiest way to start truck without key?

all engine control units are under hood easy to access. so to protect cab electrical system is useless. I can easily rise hood, find kl15 (ignition wire) on ECM wiring put a pin in it and connect with B+ wire (on starter for example), jumps starter and engine runs.

Ok, with volvo if you start engine and cab electrics is off engine idles only till you put 12V on VECU fuse. With MBE engine.... it runs at 1200 rpm w/o FR, but.... 15 pin on EECM (MR) is usually connected with FR power supply wire, so engine runs....

That's why I concider hidden cab relays useless. But brutal steering wheel bar works. to remove it thif has to cut steering wheel and it can be so fast and everyone can see it and call police. Thiefs do not like to brake windows, do something noise and long. simple car alarm helps too.

Some drivers here add hidden air valves to block park brake air lines on trailer ore trucktor, they use fuel tank locks and other stuff like it, but IMO GPS tracker is better. Over half of company trucks here got GPS trakers for better managmet and once stolen truck was found under hay LOL))))

 

i have air knob locks. Yes you could break it off, but if you do your gonna break the knobs to. It not about making your truck impossible to steel, it about making it harder then the guy next to you. Also, i dont leave my truck in sketchy areas. It also had GPS tracking with battery back up. Pulling the fuse wont turn it off. You would have to pull apart the whole dash to find it.

 

or just get a ugly truck like mine, no one would wanna steel it

 

thank you, yes the freight liner in my sig is my truck. but pretty sure a thief would pass right by my old no frills freight liner without a second look, unless of course i was hauling a high dollar load, but considering i haul dirt where often the freight bill on a load cost more than the load itself.

i do try to keep it looking the best i can but no show stopper for sure, iv got about 3/4th of each fuel tank polished sense my sig tank was taken...lol

 

Don't bet on it.
Sometimes they steal the cheapest,ugliest ones first if there is a demand for them (or their parts)

 

i do like my older truck, i do most all my own repairs. and it hauls the loads down the road for the same rates as the guys with the large cars and get good fuel millage to boot. that being said my truck looks best from the driver seat with a load in the mirrors and a check in the mailbox.
