I just installed an after market headunit in athe 2000 Mazda Mpv with a wire harness adapter. No brainer it plugged right onto stock harness it is labled so that you know what wires go where. Stereo works great but I now have no dash lights. The turn signals, low fule lights work but no lights on my speedo or tach. I have checked all wiring and fuses under the hood and under the dash. Any suggestions will help thanks!
