Does anyone have the instructions for the hella horns? I just need to know what wire goes where, according to the relay diagram. I had them installed in my max, but I threw the instructions away, and now I want to put them in the 240. If anyone knows, I'd appreciate it. Thanks in advance.

If I recall correctly the relay is a four pole and the ones marked 85 and 86 are your switch, and the other two, 30 and 87 are your power in and out. If you are running a negative trigger switch, hook up the trigger to 85, hook up constant power from the battery to both 86, and 87. hook up 30 to the positive side of the air pump, and ground the negative side to the chassis.
