KS code, and no KS connector?

[Scionguy]

its a 1989 auto n/a i think its the secnod half of the year after the cross over or whatever lol. ya the one ime ive drivin it, it seems to very little get up and go, esp in low gear. i planned to just rewire it to the ecu to be safe, becuase i finally fixed all the vac. leaks (melted my "resonator" on intake cuz the header has no sheild, fixed that lol, and rock hard ijector seats.) guess ill just have to put the new sensor wire in then. in the rewire write up, im confused why is their a ground wire strap if that outer braided winding is hooked to anyhting on the ecu? or did i just miss somethin lol. thanks fo th help guys, im not a car idiot, (i know noone said that, just stating it) i just wasnt sure about this subject.
