Horn resistance in CPU??
Anyone know off hand what it is? I ran my own setup, bypassing the CPU relay, but the horn sounds different. Im guessing that the original setup wasn't putting 12V to the horns, so I was just going to put a variable resistor in line with them.

Since the same power circuit is used for both the relay coil and the horn(s), taking the coil out of the equation will result in less of a voltage drop. Is the horn higher-pitched now?

Former Moderator. RIP Icemark.
Well there are no resistors so maybe you wired it funny, or missed one of the horns??
Normally you would bypass the CPU horn circuit with a relay wired like this:
85 to the horn switch wire coming from steering column
86, 87 to 12 volts
30 to the wire running out to the horns from the CPU.
