i have a 94 z28 that i installed a 02 ss spoiler on it and ever since i hooked up the wires for the third brake light the abs light on my dash stays on. so that means the resistance isn't the same- so how can i fix this- i don't really know anything about this type of stuff. thanks Jeff

 

One way to fix it, is to take an automotive relay and wire the relay coil in parallel with the spoiler. The resistance of the coil will satisfy the ABS computer. A simple resistor seems to overheat and that is why the relay coil is used instead.
Note that you are not using the relay as a relay is normally used, just using the coil for the resistance.

If you do a search, you may find more info. This has been discussed many times.

Here is a thread that had some explanation:
