[Z06] I rigged up a F55 ride switch to control my NPP!

I have been trying to find a sticker or sign shop to make a small radiused sticker in matte black with white text that says EXHAUST to fit perfectly over the text that says selective ride, the one shop that said they could do it wanted fifty bucks for the little sticker!
I’m going to first try and cover up the selective ride text with part of a matte black radius’d circle. I am going to have a sticker shop make a die-cut ring then I will just cut out part of it to cover up the text. I will keep asking around about having one made with the text. I would pay $20 but not 50.
@MTPZ06, I actually had that exact one in my car when I bought it. I didn't like the aftermarket looking switch. I reused the wiring from that switch and had to add a simple automotive relay and used a CPU fan cable as it fits perfectly into the f55 switch.
Thanks for posting that, that's great for people that have the later 2008 and up f55 switch. The tombstone switch is a lot simpler as it only has 3 wires.
1. Purchase a F55 ride control switch from eBay or get one new from smcautoparts.com ($95 NOS) or cheaper on eBay, part number is 15237510
2. Purchase a 3 wire CPU fan splitter from eBay or your local electronics store.
3. Purchase a fuse extender harness
and a 10A ATP full size fuse.
4. Purchase a 5 pin automotive relay (needs to have a normally closed circuit, so a 4 pin relay won't work)
5. If you don't want to solder you will need butt splices and one ring terminal and you will need about 5' of thin stranded wire 16 to 18 gauge is fine.
Here is the wiring for the F55 Switch:
6. Push the CPU fan female connector onto the pins of the selective ride switch. It fits perfectly so it shouldn't need any excessive force. If it doesn't seem to fit, try flipping the connector over.
7. Pin number 1 needs to be wired to the gray/black wire of the traction control switch. You are tapping into the circuit that provides the lighting for the switch. If you don't want it lit then just skip this step.
8. Pin number 3 (we will come back to pin 2, skipping it for now) is wired to ground. Solder or crimp on about a foot of wire and put the ring terminal on the end and use the screw that bolts the lower side of the console to the torque tube tunnel. Alternatively you can use any bolt that is grounded.
9. Now to pin 2: Solder or crimp 4' of wire onto the wire coming off pin 2 and route the wire down the passenger side of the torque tube behind the carpeting and route it into the footwell so it reaches to the fuse box area and crimp on a female insulated spade connector onto the end of the wire.
10. Now it's time to wire up the relay. Cut one of the wires on the fuse extender, On the wire that attaches to fuse holder (not the spade connector), crimp or solder 2 x 6" pigtails and put an insulated female spade connector on the end of each wire. Now connect one of the wires to pin 85 of the relay. Connect the other wire to pin 87A. Now make a short 8" pigtail and on one end put a female insulated spade connector and on the other crimp or solder it to the other wire of the fuse extender. Finally connect the wire coming from the selective ride switch that you routed to the foot well in step 9 to pin 86 of the relay.
11, You are now ready to test the switch. Plug the fuse extender into the NPP fuse location in the fuse box. Make sure you have inserted a 10A fuse into the fuse extender holder (it uses a large size fuse not the smaller mini fuses). Turn the selective ride switch from Tour to Sport and back, the relay should be operating. Start the car and repeat. In tour mode the NPP will function as normal (valves closed until 3500 RPM), in Sport mode the valves will be open all the time regardless of RPM.
12. Re-assemble console and make sure wires are routed so they are not pinched when the console is re-installed.
You have to use a relay because the F55 ride switch sends a ground signal instead of a positive 12 volts and also in the tour mode the switch circuit is open and sport closed however the NPP needs to be wired in the reverse so that when the NPP circuit is hot the valves are closed (quiet or tour mode) and when the circuit is open the valves are open (loud or sport mode).
Cost me $12 for a sign/sticker shop to cut me the matte black Halo decal. I cut out part of it to cover up the selective ride text and the color is almost an exact match! I have extra if someone else wants to do this mod. Here is a pic of the finished switch. If you click on the picture it will enlarge it in higher quality.
I'd leave it alone. I think Tour (quiet) and Sport (loud) is pretty appropriate. Now back to the $50.00 custom sticker to cover it up. I don't know how much you get paid a hour for what you do but it takes seat time in front of a computer with a couple of trial and errors to get it right. That for a one off sticker is short money.

I think I will just leave it as is. I do like the simplicity and it would be very hard to match the exact text font, color and sizing to say exhaust.
