Hi, im trying to fit an after market clock (from daihatsu cuore) into my pajero junior, and having great difficulties. Its a 4 pin connection acc+, ill, e- and b+. Ive connected it up to my stereo but nothing happens until i switch the stereo off then then clock comes on briefly. What is going on

You dont have it wired right

Just guessing:

B+ should go to +12Vdc that is always on (keepalive, battery).
Acc+ should be connected to +12Vdc when you want the clock display to be on.
Ill should be connected to a voltage somewhere between 0V and 12Vdc to control the brightness of the display. This usually comes from the car's dimmer bus.
E- should go to 0V (gnd).

How do you have it wired?

How do you have it wired?

To his stereo????

The stereo has an amp output which is live when the stereo is on... I suspect you have one of your wires going to that!!!

Thanks for the replys guys.
I have all the connections spliced into the stereo connection, i thought it would be the easiest way of connecting it but obviously i was wrong. I apologise for being a complete noob where electronics are concerned.

OK... Mitsubishi radio wires....

12v acc ( ignition ) is blue
12v Battery is Red with a black stripe
Illumination isn't connected....
Ground is via the chassis of the radio.... The connector hasn't a ground wire..

So put illumination to the blue wire... Connect the ground to the side of the radio ( some have a 4mm thread at the rear..)
