Single 3bar map feeding three devices?

[lt1camaroman93]

I have three things that need a signal from a 3bar. Please tell me I don't have to run three separate sensors? Can I just power and ground it from one thing and use the signal wire back to all three of them?

It depends on how much juice they all pull. You should be fine but look to see if your output drops when you hook them all up with a volt meter. Depending on which 3 bar you should see about 1.5-1.6 at key on.

That's good advice. You would hope that the accessories' inputs would all be as high as the sun as far as impedance goes, but I wouldn't take it for granted.
