Question about 1990 Toyota Corolla
While trying to be mcguyver and install an aftermarket radio in the car ive cut the original harness for the car and cant figure out the color codes for the radio...also my interior lights(dash/dome/etc) will no longer come on.
Did u know that they make a harness for your car that plugs into your factory harness and then adapts to your aftermarket radio? for the lights, you have blown the interior light fuse, it may be the same fuse as the cigar lighter.Below is your radio wire colors and what they do.

You have blown your Horn/hazard fuse in the under hood fuse box.
do you have any technical experience, do you know how to use a meter or test light?
here is the wiring for your car.. remember to insulate all wires and check the horn/hazard fuse and the radio fuse, also the Dome fuse..Check all fuses JUST to be sure!
