My 84 has little shock sensors on the door jams. Would they have been part of an alarm system?

 

Shock sensors? Or are you talking about the little plastic dome light switch that is spring loaded and shuts off the dome light?

84 Pickups never had an alarm option, so if there were any sort of sensors in there for an alarm, they would be aftermarket.

 

I am thinking aftermarket alarm system.

 

Do you have a magnet or something on the door as well? Looks aftermarket to me.

 

That is aftermarket for sure.

Toyota never used flathead anything in any of their trucks, nor did they put any sensors by the latch strike plate.

 

i'd be interested in seeing a better pic. i've never installed or seen a shock sensor in a door jam and have never seen one like that.

 

its a glass break sensor for and alarm system. If the truck had a pagealert alarm system they used those, hated mine everytime a big truck drove by or shopping cart bump the bumper the alarm went off
