Need some wiring harness help

Ok hive...especially all you wiring harness gurus or at least someone with a service manual.

I am trying to hook up my radar detector as this truck goes way too fast. I mounted it on left most section of the dash near the riser. I ran the cable down to under the dash and was looking for someplace to tie it in. I noticed about a dozen wires that are dead-ended and taped up to the wiring harness that passes through the firewall between the e-brake and the steering column (see pic). Don't have a clue what these are for. I want a "hot when engine on" wire so the radar detector shuts down with the truck.

Can someone tell me what these wires are for, are they fused, and is there one I can use without messing anything up? Color code?

Thanks.

I wired my Valentine 1 to a fuse that powered up with key on.

Time to get a multimeter, easy to test each wire to determine voltage, when it is hot, etc...

Looks like you need the in dash switch option..

Good luck

When i do mine, I run it to a fuse box and use a little clip that protrudes out from a "keyed" fuse and i am done with it. They cost about $.10 at most automotive stores. 10 minute job.

Askyour electrical supply for "fuse taps". Pick the radio or other such curcuit. Other alternative is upfitter switxh 3 or 4, lower amp curcuit. I use 4 switch for ipod chargeing, going to power 3 to run sat radio.

Why bother?...Once you get 'lit up', the LEO has your speed, with laser anyway...

Because my Passport pays for itself a least once a week. Driving without it is like driving naked. Not too much laser around here but it has saved me countless times from that too.

I don't speed most of the time but I do like to know where the popo is. Its the 5 over tickets that I hate the most.
