It's been a while, but I thought there was only 1 wire fused for customer access.
You have to get down on the floorboard and follow the wires coming up from the OBDII plug to find it. It's taped to the harness, tucked up under the dash and has some heat shrink on the end of the wire. Sorry, I don't remember the colors.

thanks for the reply 
i didn't think it was going to be a hard ? for the auto electrical gurus witch i am not. would i be able to use an open fuse powered by accessory with a in line fuse holder ?? wanted it to be wired in the correct fashion.

If you use the customer wire, all you need to do is make sure there is a fuse in the customer access slot in the fuse panel and you're good. No need for a second inline fuse since the wire is fused already.

#27 is a 10A customer access fuse and #29 is for the instrument cluster charge and air bag warning lights.
Do you have ESOF, heated seats, or power seat/adjustable pedals? If not, those 3 circuits are fused for 30 amps each and all 3 should be hot with the key in the run position only. Circuits 15, 17, and 18 in the box under the hood.

Before you go hooking up things to the customer wire...make sure that whatever you hook up, doesn't draw so much power that it melts the factory supplied wire. Be sure that it is thick enough to handle whatever it gets connected to.
