Thread: Re-wire 12vdc accessory socket

Well my Canadian friend... the way to do it would be to pop your console lid up and add a relay in there. Cut the orange wire going to the socket and connect it to pins 30 and 87. The add an ignition power to either pin 85 or 86 and put a constant ground to the other (85 or 86). This will only allow power to flow through the relay when the ignition is on.

Here's a little thing on relays.

And here I was going to just tap into the fuse box somehow. Glad I asked before arcing myself to the car. Would I need to add an inline fuse as there will be a heater attached? What would be the least evasive way to get ign pwr to terminal 86. Does my diagram come close?? Thanks again.

All these items in the car are already fused and that should be sufficient. Keep in mind the rating of that cig lighter is probably 10amp or 15amp at the most. Ignition power can be found in a lot of places. I think the large pink wire off the ignition switch (by base of column), radio, brown wire at HVAC and a few other places.
