remote central locking

Wondering if you could help me on this.
your switch on the dash, was it a "negative" switch. and did you have to wire in extra ground wires to change the behaviour of the remote module. I have connected the lock, unlock wires to the lock/unlock on the switch (which both have constant power), but am stuffed from there. unfortunately I only got a basic wire diagram with the unit (from jaycar), but nothing about how to wire up if system is negatively switched. might have to take it back and get something different.
thanks
Justin

Sooooo after a lot of back and forward reading/looking between the Prado and NUMEROUS forum reads, I have managed to work out how to install my Jaycar bought keyless entry unit (LR8839) into my 90 Series Prado.

In short, the Jaycar unit can only output a Positive Pulse to the door locks.
However, the Prado requires a Negative Pulse to operate the door actuators (locks).

So in order to get the system to work, you need to purchase two relays (also bought from Jaycar - SY-4045).
Seeing as though it was a pain in the backside for me to work all this out i have made up a specific wiring diagram for all those out there who may need a little help installing a Positive Pulse keyless entry system into their Prado.

This will work with any system that outputs a positive pulse, but keep in mind the wire colours may be different.
Basically, what the relays are doing is converting the positive pulse to negative by grounding the door lock/unlock wire.

If i have helped at least one person out there, then it was worth making the diagram, because there is nothing worse than frustration over such a simple install.

Nice work jasnmel252. Nice clear well drawn up diagram.

Hey mate, just replied to your other post regarding this which makes that one irrelevant but for what it’s worth, you could’ve actually intercepted the drivers door actuator wiring in the kick panel and used the Jaycar module to drive that independently without the need to add additional relays. But you got it sorted so it’s all good!

I'm in desperate need of that diagram if at all possible.

Hi all
i have a mongoose mcl3000 going into an 08 Prado I have connected orange black and purple to ground and red to positive
At door panel I have blue/yellow which lights up on lock and blue/black which lights up on unlock(test light) I have connected green to blue/black and blue to blue yellow but all I get is clicking sound at module
anyone have any idea
