First my sterio stopped working, dosn't power up or anything. Then when I put the ignition on the speedo ODO reading displays and the Trip counter resets, the A/c control unit also resets and turns on the A/c pump. No fuses that I can see have tripped and ive disconnected the battery for 3hours to reset the ECU. Before I did the reset the trip computer didnt clock up the miles but the ODO did, now they both seem to work ok untill you turn the ignition off, then the trip coumputer resets itself and the A/c comes on.
Im puzzled as to what could cause this problem to arrise, the cars fine to drive and everthing else works A.Ok. starting to get worried.
Ive removed the Sterio and noticed that my Hazzard warning light power feed comes off the same feed as the sterio. Is there anyway that this could've effected any of the cars other electrical systems??
Has anyone had anything similar happen to them ??! Any technoheads out there that could help diagnose a problem.....
So i'd get that sorted whilst your stereo is out! As for the problems I ain't to sure mate! 
Had a look and the extra wire to the sterio, its been spliced into the original feed for the Hazzards!! 
Althought its kinda involving my sterio!
