i have a 91 s13 se model and im trying to install a alpine headunit...but the radio harness doesnt seem to have power...i already checked the audio fuse on the driver side kick pannel and i replaced it because it was blown...but still no power....has anybody had this problem?

Aftermarket head units use two power sources, constant +12v and Ignition-switched +12v... have you tested for either with a multimeter to see which is missing? Also, it could be that you've got power and just don't have a ground - make sure that the 'black' wire coming off your conversion harness is grounded, if it has one with a ring terminal/etc on it.

There's more fuses under the hood you know. Why not check them all?

+1 for checking them all...it's always something crazy.

Stupid question. Did you connect the ground wire of the test light to chassis ground?

If you're so smart then why don't you open a FSM and start tracing out the schematics? Start at the battery and check all wires and fuses for continuity?
