Is there an easy wasy to run a direct line that only gets power with the ign. or acc. position of the key. Obviously I don't know anything about wiring, so if you answer please give a short explanation. Right now i've been just hard wiring into switched items on the fusebox.
Thanks,
Geoff

The + side of the coil uses a hot in acc. Im not sure if it would be okay to tap into that wire, or not...

Also, I think there is a wire on the starter solenoid that is hot in acc.

The easiest way to find stuff like that, is to buy a test light, try to figure it out for yourself.

Something Ive always done for my vehichles is, wire up a terminal block with ground, hot in acc, and constant hot. It saves time and complication further down the road when installing a stereo system, CB, or what ever else...

Hi there.

Kinda' depends on what you mean by "easy", and how much power you need.

The best way is like Jon described, by wiring up a block somewhere that has the leads, for future upgrades.

I think the best way to do this for the acc. position is to tap into the wires at the ignition, and run a wire to a relay switch. Then wire (with a nice thick 12 gage wire which will give you 20 Amps of current available in the block. If you want more, you'll need a thicker wire. Whatever it is, make sure the relay switch you buy is rated for it.

Anyway, you'll wire the hot lead from the battery with that thick wire, to the relay switch, then to the block you're putting in.

Probably wouldn't be a bad idea to put in an inline fuse somewhere on this wire, before the relay switch, just in case.

The way this thing works is, from now on, all you'll need to do is tap into the block you've added, for whatever thing you're installing.

The way a switch works is this (just in case you don't know already). When you turn the key, that sends a small amount of current (hence, only a small wire is necessary) to the relay. This causes the "switch" to move into position that will now make a connection FROM the battery wire (thick) TO the out wire (thick wire) to the block. When you turn off the key, the switch loses its small current, and then "opens" up the circuit for the large wire.

it's really not complicated to wire up, and any cheap wiring book will show you exactly how to do it, in case you're worried. But really, to put in a relay will only add a couple minutes to the install, and will give a clean, professional installation.

It should be fused for sure, but not just anywhere - within ~12" of the battery.
