Can someone help me edit this?

So I'm trying to edit the control scheme for a tank turret. So by default, WASD controls the turret in terms of rotation and gun elevation (W/S for Up/Down) IN A SEPARATE SEAT. The first script is the script "Control" in the gunner seat. The rest follow as: "Control2" and "Pickup" which are all in the gunner's seat. Which script do I edit so instead of "WASD" for turret controls its "UHJK" (U:Elevation UP H: Turret turn left J: Elevation DOWN K: Turret turn right)

while true do
wait()
if script.Parent.Steer == 1 then
script.Parent.Swiv:play()
script.Parent.Parent.WER.Value.C0 = script.Parent.Parent.WER.Value.C0 * CFrame.fromEulerAnglesXYZ(0,0.01,0)
elseif script.Parent.Steer == -1 then
script.Parent.Swiv:play()
script.Parent.Parent.WER.Value.C0 = script.Parent.Parent.WER.Value.C0 * CFrame.fromEulerAnglesXYZ(0,-0.01,0)
elseif script.Parent.Steer == 0 and script.Parent.Throttle == 0 then
script.Parent.Swiv:pause()
end
end

"Control2"

angle = 0

while true do
wait()
if script.Parent.Throttle == 1 and angle < 20 then
script.Parent.Swiv:play()
angle = angle + 1
script.Parent.Parent.WER2.Value.C0 = script.Parent.Parent.WER2.Value.C0 * CFrame.fromEulerAnglesXYZ(-0.01,0,0)
elseif script.Parent.Throttle == -1 and angle > -15 then
script.Parent.Swiv:play()
angle = angle - 1
script.Parent.Parent.WER2.Value.C0 = script.Parent.Parent.WER2.Value.C0 * CFrame.fromEulerAnglesXYZ(0.01,0,0)
end
end

"Pickup"

script.Parent.ChildAdded:connect(function(w)
print("ChildAdded")
if w.className=="Weld" then
print("IsAWeld")
if w.Name=="SeatWeld" then
print("IsASeatWeld")
if w.Part1.Parent:findFirstChild("Humanoid")~=nil then
print("IsAHumanoid")
pl=game.Players:GetPlayerFromCharacter(w.Part1.Parent)
if pl~=nil then
print("IsAPlayer")
if pl.PlayerGui:findFirstChild("VehicleGui")~=nil then
print("found vehicle gui - deleting")
pl.PlayerGui:findFirstChild("VehicleGui").Parent=nil
print("deleted")
else
print("no gui found - adding")
newgui=script.Parent.VehicleGui:clone()
newgui.Parent=pl.PlayerGui
newgui.Vehicle.Value=script.Parent.Parent
print("added")
end
end
end
end
end
end)

script.Parent.ChildRemoved:connect(function(w)
print("ChildRemoved")
if w.className=="Weld" then
print("IsAWeld")
if w.Name=="SeatWeld" then
print("IsASeatWeld")
if w.Part1.Parent:findFirstChild("Humanoid")~=nil then
print("IsAHumanoid")
pl=game.Players:GetPlayerFromCharacter(w.Part1.Parent)
if pl~=nil then
print("IsAPlayer")
if pl.PlayerGui:findFirstChild("VehicleGui")~=nil then
print("found vehicle gui - deleting")
pl.PlayerGui:findFirstChild("VehicleGui").Parent=nil
print("deleted")
else
print("no gui found - wierd...")

end
end
