Hi. On the weekend I was working on the harnesses under the dash and I didn't thought I could short out anything, but apparently I did, and all the diodes and micro-chips are gone in the head unit of the alarm.... I want to see if I can get some new car alarm (2way with shock sensor) for reasonable price- currently I had Ungo MS2000, so old crap.... BUT if the price will be greater than $150 I will spend one evening repairing that old ... just let me know if there is anything available in that price range. (I will install it myself) Thanks, Luke.
