I have a 93 ranger that came with no power locks, so i bought some actuators and switches off ebay. I was looking at the door lock diagrams on here but there is more than one so im not sure which to use.

These are the switches i have (2)
https://www./itm/121270753189?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1497.l2649


and the basic 2 wire actuator, i was just wondering which diagram to follow. I have an Avital 5103 Alarm id like to wire in aswell, it has 2 wires that change polarity for the lock outputs.

The link for the switches messed up, but it has 1 Red wire, 2 Black wires, a Green and a Blue wire.

Go to the downloads section of this site. Search for Viper 5701. Download the install manual for the older style. On page 38 is a diagram for aftermarket actuators.
Two relays needed or a DEI 451M.
Piece of cake.

Another helpful download is Door Locks DF 1041


This from harryharris from a different post:

connect 87a on your relays to ground?
85 lock or unlock outputs
86 and 87 12V+ constant fused at 25 amps for 4 locks, 15 for two.
30s are lock outputs
87a ground

Thank you very much! i printed the page out so i can read it while doing it hah. It does not matter that the alarms door locks change polarity?

No use green as lock and blue as unlock, this will give you NEG (-) outputs.
As a safety precaution regarding the Avital's lock outputs which are known as flip-flop type diode those lock wires, 1N4004, with the bands towards the Avital.

You mean the anode on the avital side?

Band towards Avital means that the Avital lock wires will pass only NEG pulses.

I have this wired up, and it works with my alarm, and with ONE door switch hooked up, when i wire in the second switch and use it, it pops the fuse, i guess because the switch sends +12v to the ground, because the outputs on my switch are always grounded unless pressed, do i need to add another diode somewhere?

Take the switches, wire ground to the centre terminal then the outside terminals back to the 451,joining them to your Avital units blue and green, then to the 451 or two relays.
The motor wires from each will now go straight back to the 451.
Now look in the relay section, add actuators.

I dont quite understand, I have everything wired, my alarm locks and unlocks it, my drivers switch works, but ONLY when the passengers switch is disconnected. I have 2 relays installed this is what i followed

https://www.the12volt.com/12voltimages/5wap.gif

my problem is when i hook up the second switch and try to use EITHER switch, i pop a fuse, or if i dont, the locks barely move. I think since both the switch outputs rest on ground, and one has +12v when applied, the other switch output stays grounded, so the grounded wire sees the +12v and there lies the problem, i just dont know how to fix it or wire it another way.

The reason is that you have two switches which are wired in parallel.
Remember with these switches when not used the grounds are connected to both motor wires.
Thus when you actuate one, you're connecting your centre live to either the blue or green and the ground (black)stays in contact with the other colour, unfortunately the other switch still has the both motor wires connected to ground = dead short = fuse blow.
I know you don't understand it's quite hard and I'm not going to write a whole page on switching permanent motor magnets, suffice here are your options.
a)Revert to one switch.
b)If the switches have five contacts in a straight line,
1) Pull the motor wires away from the switches and wire them directly to either the 451 or 2 relays, whatever you used. In the relay section you will have a diagram showing how to wire "add actuators" use that as a reference.
2) Remove the 12V+ feeds from the centre of each switch and discard.
Now remove the two grounds from each switch discard one and connect the other to the centre terminal where your power supply was before.
3) On the outer terminals run a lead from one side to the green coming from the alarm the other side to the blue, i.e. the lock/unlock wires from the alarm before the 451 or relays.
So; each switch is now configured thus:
5 terminals, top to bottom (1)lock wire from alarm, (2)empty (3)ground
(4)empty (5) unlock wire from alarm.
This will now work for you.
