12volt switched wire under dash with easy access

[Squatinbull]

Hey guys, 

Im looking for any recs on a 12 volt switched wire to hook my 2low kit up to that is convenient under the dash. I was thinking of going with the upper cig lighter, but if there are any that are easier to get to id entertain the feedback. Thanks.

Here is the power point I created.

 

4 Terminal strip.

1. +12V Battery power
2. +12V Ignition Switched Power
3. Panel Lighting (Dimmer)
4. Ground

One fused wire comes from the battery (20 Amp Fused). Now once in the cab using a relay I've get trigger for the relay from a fuse. This way there is no load on the stock electrical and no way to cause damage. This relay gets power from terminal #1 and passes the power on  terminal #2 when triggered. Since I installed a aftermarket stereo I had the extra lead for the panel lights so I ran it to terminal #3. Terminal #4 is a direct lead from the battery ground. Nothing attaches to the stock other than a trigger from a keyed fuse. Completely isolated and protected.

I preciate the help. sounds like a good way to go. Another trip back to the parts store.. woohoo! Definitely gonna get some go figure looks from the lady friend. ha. Im doing this just after installing the '09 steering components and trac bar conversion kit.

Ok, now my question is how did you create the trigger from a keyed fuse? When it comes to electrical, im lost usually.

Looking at a relay...

 

85 is to body ground

86 is to the keyed ignition fuse of the cab fuse panel. Get a fuse tap for this.

 

30 is from the #1 terminal of the strip.

87a is back to the #2 terminal of the strip.

That's a really good idea. Where do you locate the block?

[Mopar1973Man]

Anywhere in the cab you wish. Mine is located behind the knee bolster.

Makes sense to tap in to each system once and not have multiple taps every time you add an accessory. This should be a first mod you do. An electrical investment into the future.

Here is where I put the relays for a mystery switch set up .
