Hi guys! Well I bought a keyless entry kit for my TS today. It already has central locking, but I wanted keyless entry. The instructions that came for it are of absolutely no use for magnas! (well, 2nd gen ones anyway) :rant: . After much searching of this website, I wasnt able to find anything, so I had to work it out on my own. Here is how i did it.
There is a red wire with a white stripe on it that goes into the relay. This wire comes from the drivers side door latch. If this wire is connected to ground, the doors unlock. If it isnt connected to ground, the doors lock. (see attched pic). The jaycar unit has many wires: red and black go to power, purple is for flashing indicators/park lights (whateva u want really). The rest are set up with relays. There are 2 sets of wires which are connected so they conduct except for when a button is pushed, they dont for a second. One button does one set, the other does the other set. Seems logical. There is then another two sets, but vise versa. (dont normally conduct, but do for a second when a button is pressed).
At first, I thought wtf, as they way they described installing into a car which already has central locking, and uses a down, up and common wire.
I worked out that the relay connected to the green wire and the yellow/black wire is normally open, and closes for a second when the green button is pressed.
The relay connected to grey wire and the blue wire is normally closed, and opens when......
Now to the proper wiring.....
The central locking relay is kept in the drivers side kick panel. A screw and weird looking nut hold this down.
Where the red/white wire goes into the relay, i connected the green wire. I then conencted the yellow/black wire to ground. (it doesnt matter about which way the wires go, ie green to ground, y/b to relay). When I press the green button, the doors unlocked. Yay! Working out how to lock them was then the trouble......
I made a cut in the red/white wire, and attached the grey and blue wires in, so the wire now goes via a relay. This is the relay that is normally closed. (meaning that the doors can still be unlocked with the key). If the doors are unlocked, the relay is grounded. when the red button is pressed, that ground gets disconnected, and the doors lock. when the relay closes again, the doors stay locked. Hurrah! All wired up :D . Then the fun came of stuffing it all back in.....
Attached is a diagram of the wiring, before keyless entry and after keyless entry
