rx300 door locks

hi, that car had a lock "sense" wire that must be interupted inorder to work properly. You must go into the driver door , and find the wires at the switch: gray- lock detection,  pink-lock,  and pink/blue for unlock.

You'll need a relay and 2 diodes,  wire as follows:

First,  cut the gray wire at the switch, connect the switch side to 87a, and the other side to 30.

86 goes to 12 volts, 85 goes to your negative unlock wire output from the alarm, and also connect this to the pink lock wire on the lock switch.\

Now take your 2 diodes and twist anode sides(stripe side) together and connect to your negative unlock output from the alarm, this leaves you with two diode ends left. Connect one end to the pink/blue unlock and the other end connects to 30 of your relay.

good luck, hope this helps.
