i have never posted on this forum before so im pretty sure im doing something wrong(hopefully i dont get flamed and trolled for it like i did on dezertrangers) but anyway, i have a 1990 toyota extra cab p/u i got from a friend of my dads for $800, and it has the manual roll up doors and all that. well i want electric roll up doors would my truck be wired for that(so would it work if i just go to the wrecking yard and pick up some doors?) my dad is big into offroad cars and fabrication and stuff, and he does everything himself so i got someone experienced who can help me through most of the stuff
i also got a few other questions if anyone wants to take the time to email me and help me out there thnx
