I tapped into the power drop on my lumina. Not sure if the bonneville has one or not. I would do the seats or Cigarette lighter myself as i don't use those that often.

Any wire that you are tapping to power, use a 10 amp fuse on each.

I got the power for each relay under the seat at the power seat wire. I think it'* like 10 gauge..maybe 5. Also go ground there.

That should leave you with only 1 wire to the switches that you need ignition power for. I already had run one...

Thank-you Geoff. I hope to try this out in the couple of days.

Thank-you Bill
I bought the fuse holders the other day- and I couldn't remember if it was 10 or 15 amp. What should I tap off for the run only circuit?

It'* basically your choice. I forget which one I used..but found an used ignition circuit and used that.

This will be attempted on tuesday. All I need now is some 14 guage wire. Talked to the Randman...

not ot hijack But i just got Caddy heated seats out of a STS

I've done two sets now and it'* really just as easy as it seems. You have tested the pads to make sure they all work before putting them into the seats right?

Under each seat you hook up power and ground for the relay.
Then supply the switches with power and ground.

Switches hook to relays, relays hook to seat pads.

I know what that feels like.....how much did they charge you?
Now I know what to do- just have to find the time...wendnesday I think....
pics for sure!
