i bought Metra brand mounting bracket. and Metra brand wiring harness. ...i just got the cheap ones caz i dont care about the chimes... but i ran into a problem after wiring the harness up. i used a check light [dunno its proper name, lol] to see if i had power. it did have battery power. but nothing on ignition!!!!!! WTF?!?!?! ...everything is connected good, and the right way. i checked thousnads of times after i found out it wasnt working! so i guess my question is, WHUTS WRONG WITH IT??? ....as for right now the ignotion wire on the harness is sliced into the ignotion of the fan on my AC/heat. i dunno if this is good or not either. umm, its not fused ATM so when i turn the fan on the radio turns off. but at the end of the week when i have more time i will fuse it so everything works correctl. oh! i have another question. ....if i fuse it. [only if there is no answer to the first question, that can be done super easily!] DO I USE THE FUSE SIZE OF MY RADIO TO FUSE IT? OR DO I USE THE SIZE FUZE OF MY AC/HEAT????

thanks!

You need to read the sticky at the top of the page.... covers all that and more.

2000 + do not have switched accessory turn on in the radio harness. Grab it at the ignition wire under the dash and inline fuse within 6 inches.
