Anyone Done A Deck In a Mack Truck?

tomorrow I have to install a deck into a brand new Mack Truck...I was just wondering if anyone has done this yet and if they have any diagrams as far as wiring colors?

thanx...

it is a panasonic stock hu...

I guess only the dealership would have a book which detailed the wire numbers as to where they all go and what they control...

any other info would be appreciated...the truck arrives in about 4 or 5 hours...

thanx for the input guys!

I drove for about a year and a 1/2. I installed a kenwood deck two amps and two twelves in my frieghtliner. I also installed a pioneer set up in a peter built. I thought it was easier to install in the trucks. keeping the stock radio in place, I just marked the acc,ground and constant 12+ before starting. I grounded the head unit to the frame just behind the radio. used a tester to check for any other hot wires before connecting the speakers. Make sure you connect the speaker wires correctly, if you don't connect  R+ from the h/u to R+ to speaker R- from h/u to R- to speaker you will get very agravating engine whine. If the mack you're driving has a volume control by the bunk by pass it, cut the input wires going into the volume control and connect them to the rear speakers. that volume cotrol gave me a lot of problems. i don't know if it was common ground or hat but the rear speakers wouldn't work while this was hooked up. because all of your batteries sit right under the bunk i had no problem running amp wires to the batteries. there are circular cut outs already there so i pushed the wires through. in a nut shell it worked out well for me, my box fit under my bunk so nothing in the floor.
