As for installing it just simple change of parts. The flasher is found in your driver side of the dash. If the flasher been there a while then it might be difficult to remove. Just take your time and work the flasher it will come out. Pull the stock flasher out and plug in the new flasher. The replacement flasher can is slightly larger for the 12V dash. It will barely fit. Make sure to get the electronic flasher can.
As for the taillights you need a T25 screwdriver. There are 2 screws holding each taillight in place. The outside edge is a set of pins into the body. Need to be firm but careful and pull the light straight out. Top bulbs are your tail lights simply twist the socket and it should come out. Simply change the bulbs out. Leave the bulb out of the taillight for testing.
Front marker lights for stock marker there is a Phillips screw holding the light in place on the bottom. Then just pull forward. Twist the socket and remove. Now change out the bulb. Again leave the bulb out for testing.
Aftermarket headlight you might have a unit like my own which the marker light is part of the headlight. This you'll need to remove the 3 10mm bolts and pull the headlight forward to gain access to the marker lights. After that, it is just like the stock marker light. Twist the socket to remove and change the bulb out. On stock headlights its a Phillips screw on the bottom then the marker light can be removed.
Now testing you want to simply turn on the parking lamps and see if the front marker lights are both white and the rear taillights are dim red. Now you can hit the hazards and check and see if the front marker lights turn amber and the rear taillight flash bright red. If any of the bulbs are backward pull them out and turn then 180 and resocket the bulb. This should fix this problem.
As for the bulbs listed above, I'm using a switchback bulb in the front marker lights. This bulb will be white light on parking lamps and when a turn signal or hazards turn on the bulb automatically switches from white to amber. A member brought up laws might be in effect for white marker lamps in front. Might want to check with local laws on this.
