Do you need another relay to wire the factory horn to an astrostart 2100 in a 1996 suzuki esteem and if not how do you wire it

Connect the P2 light green directly to the blue/black at the column, on your car!

A relay should not be needed. if it is .... wire like so.

87 to ground

86 12volts fused

85 the P2 light green

30 to the blue/black on your car.

87a not used
