Here's the link to that Mod.
If I remember correctly, it is the right side relay, I don't remember which pin I bent though. I want to say it was the pin furthest from front, but check the link just in case.
For other people wanting to do this Mod:
The relay for this on older TJ's is behind the glove box, and is under the hood for newer TJ's.
Did you ever get those Red LED's installed, Giancarlo?
