Spoiler disconnect
Hi all,
I decided to disconnect my spoiler yesterday, a simple mod on my 1991 C2 as it just involved unplugging the module under the passenger dash. I prefer the look and figured that it will mitigate a potential mechanism failure at some stage , I've already had to change the worm gear twice over the years!
Anybody else do this? I did notice she runs a little hotter but I do have the oil thermostat mod and so it never goes above 9 o'clock on the gauge. I rarely drive at over 120mph and so don't believe it will impact stability but interested to hear other people's views.
CheersTim

Have you thought about modifying your spoiler control unit?
I have changed one resistor and spoiler goes up at 62 mph, not cycling during city driving.
Very pleased with the modification and the cost.

^^ I also did the mod with my '90 that keeps the spoiler down until 62 mph and keeps it elevated until I lower it with the switch. The spoiler stays down around town and only goes up once if I go over 62. I just pulled one wire from the control unit and taped it off.

Are you saying that your mod did not need a resistor change?

That's correct. I think it only works on early cars where the spoiler module is under the passenger seat. I slid the seat forward and reached the module, opened it up and pulled one wire out of the module, taped off that wire and put it back together. About 15 minutes. In the early cars there's a second sensor that raises the wing at 62 MPH but it doesn't retract the wing when you stop. The wing stays down around town (unless you're driving pretty fast). Once it goes up it does not cycle up and down. It just stays up until you use the **** on the console to lower the wing.
Here are the steps I followed from a prior thread to modify the spoiler control. I have these steps in my Targa rebuild thread but I can't fine the original thread.
1. unplug the control unit wire harness (you don't even need to unscrew the control unit from the bracket) - 90 and 91 cars have this unit under the passenger seat so it might be a bit more difficult to reach it...
2. holding the plug from the wire harness, use a flat head screwdriver to pop off the back of the plug to see the wires
3. Slide out the #8 pin (green wire), and #12 pin (white/red) - they are labeled from the mating surface of the plug
4. Fold over those wires so you can close back up the plug - snap it back together
5. cover the wires with electrical tape, plug everything back in
You are all set! You will now have a spoiler that is activated ONLY by the dash/console switch - it will no longer come up at speed. This was done on my 92 964s - so I would assume it would work for any post-89 964, but I am not sure about it. Also, I believe the 92, 93, 94 all have the control unit above the passenger's feet, while the early 964's have the control unit below the passenger's butt.

Hi,
is this a mod that doesn't give the warning light?
Thanks!
