I was looking at my Profec B and noticed that there was something that looked like an earphone jack and it was labeled "Option." It's supposed to be for the remote switch reciever. Has anyone attempted to make their own with out using a remote system and maybe a switch and wire running to the jack?

 

i found this a while ago. its not that good of a write up but its something:

Wow that's exactly what I wanted to do. Use the horn swtich to control the boost select. I took my air horns off when I removed the intercooler so I have no horns anyhow. Thanks for your help

Anyone have any experience with this?

 

One idea I had....make a toggle switch between horns and boost controller. Have it set so that normally your horns work...but when you flip the switch they control your profec. Best of both worlds.

I'll probably try this this summer.

 

Any idea why he has 2 wires comming off the Horn signal wire?

 

Oh I see, I'm an idiot I see the 2nd wire now.
