    On the Mitsubishi Pajero 4 with a 3.2 L diesel engine is suitable. Turns on automatically when the engine runs over the voltage on the on-board network. But sometimes it turns on randomly, you approach the car, and the projection burns. Can put the battery.

    Товар прибыл в течении недели, доставил курьер.
    Описание соответствует, качество не плохое еще и за цену ниже 1К.
    включает в себя комбинацию скорости, вольтметра, температуры ОЖ, тахометр четко реагирует (1 деление = 250 об/мин).
    Подключается прям изи – воткнул в OBD разъем и погнали…)))

    Delivery to Tashkent took 55 days, everything was tracked, the projectors are reliably packed in a box and then each in a brand box with a cover. Previously took similar with less functionality and all of them are of good quality, these are also suitable for many of our Chevrolet machines and not only, Everything works correctly and shows, a friend set himself a similar one to spark and said he very much helped out, because. It shows the temperature of water (which is not on the sparks and cobalt and so on), it had a temperature of as much as 116 degrees and the engine almost boil, and it well if not for a similar projector, maybe he would have the engine would have died, I think I’ll order more and put myself this on cobalt, After all, it is more fancy than similar, the seller and I definitely recommend it!
