You do have to remove the bumper.. which in itself is a job n half. They used a ton of fasteners. Also a good thing to remember is this assembly is designed to be assembled, not the other way around, so its a bit tedious to do it right without breaking anything. The side markers are pretty interesting. There's diy's on here if you search. There's one that displays a way to get the bumper off without removing the marker lights.. that worked quite well. Once the bumper was off I used a small pick to slowly and carefully wedge the metal clips for the marker lights from behind and they pop right out. Going back in is a matter of just putting bulb in, lining them up and pushing them in. No broken metal tabs makes for a good re-install.
The Relay style install was pretty easy but I did set up the harness and relay on a previous car. Relays are pretty easy to wire up and only require 4 connections. One for trigger (factory horn wire) one to ground the relay itself, one is power from the battery and the other is the lead that will power the horns. Deeper descriptions of relaying wiring can be found on
www.the12volt.com .
Granted, it wasn't NEEDED for the FRS but since I already had it ready to go and it allowed me to not cut any wiring (leaving ability to go back to factory later if need be) I chose to go this route. I also used a relay socket from parts express (
www.partsexpress.com ) that makes it easier to wire and if the relay needs replacement later its as simple as removing the old and plugging in a new.
Time wise, took me about a hour n half of actual work taking my sweet old time. Most of that was removing the bumper, the rest was making sure everything was neat and bundled correctly (loose wires make fires). Mounting was pretty simple.. I used the factory high tone horn bracket and grounded to the horns to their mounting point similar to the install detailed above. Here are some pics.
No wires showing, I made sure to run the power wire in tight with the factory harness and keep it under the factory terminal cover.
lol.. that's funny, cuz I'd much rather sound like a poser than have some asshat drive into me while not paying attention.
Weigh it.. poser with intact shiny car, or cool guy at body shop getting chevy stamp removed... I'd take the former vs latter all day every day.
