indicator flash on unlock solution

Look above the throttle pedal there's a black plastic box with multiple plugs of different colours. Called the GEM box. The simplest way is to find the unlock motor wire which is probably white or WHITE/ black. Open the driver's door then throw the latch on the door lock (back end of door). Use the locking push in the inner handle to make sure the locks work, i.e. lock and unlock and you are ready to go. Take a DMM* and set it to 20VDC. Place the black probe to a good ground (earth)and the red side to to one of those wires. when you push the handle or use the remote fob to unlock, one of those wires will read 12v+.  That's the one you want. Also on that box are a plain blue and a blue/red wire adjacent to each other. These are your indicator wires. Again use a DMM the same way to test. Once you've ascertained this, connect the  unlock motor wire to relay 86,  earth to 85, constant 12v+ (probably a ORANGE / colour) adjacent to the indicators, again test) to 30 and from 87 split via 2 x 2N5404 diodes, bands away from relay to your blue and blue red indicator wires.

You can make this more sophisticated with an ignition control relay such that it only works when ignition is off; take a feed from an ignition circuit (should be GREEN/ YELLOW in the ignition loom) to a second relay 86, ground to 85, then take the 87 wire from the first relay, bring it to 30 and out from 87a.

* You can do all this with a test light but it's not advisable because I know what I'm doing here, I wrote the play book for Clifford on this car and you might feed 12V to the wrong wire and blow the box. You could also conceivably do this without the first relay, just diodes but it's inadvisable long term.
