///M Roadster Foglight Installation

Pros: Increased visibility, looks
Cons: none?
Cost: Less than $200 installed

As we all know, ///M Roadsters do NOT come with factory foglights as either standard or optional equipment. In order to obtain them, we must look to aftermarket suppliers. The decision as to whether or not I needed them was made for me by virtue of the fact that I live on Cape Cod, which just may be the Fog Capital of the Eastern Seaboard. After seeing Walter’s at the Escape to the Cape Drive this year, I know I would be purchasing a similar model. Walter had chosen PIAA 1400’s in Amber. I opted for the same lights but picked the clear lens version, as they are a bit brighter. I purchased them for $149.95 from 4 Wheel Parts Wholesalers (800-421-1050) as they had the best price.

When they arrived, the only question in my mind was where to mount them. Walter mounted his in the engine intake and they look quite good there. I, however, being the Contrarian that I am, decided to mount them in the outer (brake cooling) intakes. Please note that these lights are very small and should not seriously impede the airflow to the disc brakes.

Wiring these lights was easy, I mean REALLY easy. It should take about 1.5 hours for most anyone.

Step #1 – The switch wires and switch:

The first step is to unravel the wiring harness provided with the foglights. I decided to mount the relay (included) and the fuse holder (also included) in the factory fuse box. This would keep the electronics centrally located and dry. Cut the 2 wires that run to the switch plug about 24 inches from the switch plug itself.

Snake the cut wires through the large grommet already in the firewall on the driver’s side.

Unscrew the fuse holder (remove 2 front screws and loosen 2 read screws) so that you may lift it up.

This will allow some additional access to feed the wires up and through the factory hole in the bottom of the fuse holder.

Once that is done, attach a female spade connector to the input side of the switch wire and (using a fuse tap) connect to the switched side of fuse #44 (note: this photo shows the wire tapped into fuse #33 which is not switched). Attaching the wire to this location will allow the foglights to be turned on whenever the ignition is on. Some locations may require that they be wired in such a way that they may only be turned on when the low beams are on. If this is this case in your area, then you may want to tie this wire into your low beam power wire.

The switch itself was mounted to the knockout panel to the left of the steering wheel where the factory switch is located. I simply trimmed the back of the switch to allow the wire to run straight off the back and I drilled a small hole in the knockout panel. The switch was attached with 2 sided tape. Finally, ground the switch to one of the 4 brass bolts under the driver’s side of the dash (I think they are 7 mm).

Step #2 – The rest of the wiring:

Remember that the entire wiring harness is complete when you buy the kit so the only connections that have to be made are power, ground and any wires you cut during the installation itself.

Re-attached the switch wires that you cut. Run all the ground leads down through the fuse holder and out the front (via the rubber grommet there). Route them towards the factory ground point on the front left fenderwall. They may all be grounded here.

Run the wires for the lights out the same rubber grommet and down towards the front grill. The wires may be hidden in the factory wire-loom. This picture shows the foglight wires hidden inside the factory wire-loom and the ground wires grounded at the factory ground point. At this point, the last wire to connect will be the power wire. It can be connected to the hot side of the fuse box (passenger’s side) below the fuses. You will see a nut than can be unscrewed and the power lead attached. I couldn’t get a good shot of this but you will see what I mean. This is an adequate source of power as the foglight kit has it’s own in-line fuse. Once connected, you may screw the 4 screws back in place that hold the fuse box down.

At this point, all you need to do is wire-tie the relay, in-line fuse and extra wiring neatly together and put the top back on the fuse box.

Step #3 – Mounting the foglights:

Run the foglight wires so that they are just to the driver’s side of their respective brake air intakes. Then, carefully cut a small slice in the plastic (about 8” inside the intake) and pull the wire through. The foglights are attached using 2 sided tape and screws (optional). The 2 sided tape is really strong and should be enough to hold them in place. Plug the foglights into the wiring harness and turn them on. If you installed them correctly, they should work. Turn them off again so they don’t get too hot to handle. Unscrew the mounting plates but don’t remove them. Stick the 2 sided tape to the mounting plate and hold the light in the brake intake duct. With the lights (low beams too) on and shining at a wall, aim the foglights where you want them.

Only concern yourself with the left-to-right angle at this time. When they are pointing where you want them, stick them to the roof of the intake. At this point, you have just mounted the mounting plates. Remove the foglights only and ensure that the mounting plates are firmly attached. If you wish, you may at this time use the screws included with the kit. Re-attach the foglight to the mounting plate and adjust the up-and-down angle before tightening completely. Repeat for the other side and it should look like this.

Step #4 – Enjoy!

They greatly increase your visibility off to the sides of the road as well as in the fog without blinding oncoming traffic. I’m quite pleased with the results – for safety as well as aesthetic reasons.
