i dont know if im posting this in the right section so im prepared to get flamed but anyway, i have a 1990 toyota extra cab truck and i have a few questions about the it (the doors specifically)
i want to have power windows and locks; so do i need to get a kit to have this installed, or can i just get some doors from a model that came with those and put them on and wire em up? so i guess im asking if a 1990toyota extra cab pickup has the wiring already for this (in a way)
also, how do i fix a sagging door? i cant seem to find a legit looking replacement door hinge, does anyone have a link to that or advice on how to do it? thank you

 

junkyard, grab hinges and doors and wire them you maybe prewired you will find it if you are

 

well you can get a kit or swap the guts from a equipped truck/4runner I am not sure if your truck will have the plugs available so you might need all the wiring from the donor vehicle such as relays and fuse locations if you want to keep it as stock looking as possible. I bought a kit from e-bay for the door locks for about 75 for 4 actuators so i could have electric locks and alarm system. took 15 min per door and 1 hr for the alarm setup.

 

Get junkyard door hinges, there are only two different hinges, top/bottom, the top of one side will fit the bottom of the other.

The truck won't be pre-wired. You need to grab as much factory wiring as you can (tight when it routes into the truck) and make sure you grab the gray relay box. That's the brains of the system..
