03 accord Rear defrost wire location?

I am in need of a convenient wire location on the rear defrost line of an 03 Accord!!! if anyone has seen an 03 accord dash there just isnt an easy way to get to the back of this unit!! so i was hoping for an easier way???

Ok it doesnt need to be convenient!! I just need a wire that when added either power or ground it switches the rear defrost on!!! I have check several wires and have been unsuccessful!! There has to be someone out there that has done this!

What are you trying to do? Are you trying to activate rear defrost with a remote start unit?

yes i am tryin to get the rear defrost to come on during remote start, and originally i wanted to make it easy and not have to remove the whole radion unit!! Too late, i already took that out, i found the wire yellow/black in the green plug on the back of the HVAC unit that shows 12v when off and 0 volt when the rear defrost button is pressed!!! but i cant seem to get that wire to work with me in a relay!! I have tried to send a ground to the wire to turn it on and even a power!! both were unsuccesful in turning on the rear defrost!!! so im torn!

There are 2 places to get the defroster trigger wire. The easiest is under the dash in the harness coming from behind  the fuse box. Its BLACK / YELLOW, it's a REAL heavy guage wire, it needs a latched POS(+) pulse...... The other location is under the hood. @ the defroster relay. The other way requires soldering onto a pin on the relay under the hood.

I will try to find the wire first but other wise i will try the two relay part!!! but will this still allow me to manually turn on the rear defrost by just pushing the button??

I think the defroster wiring in the 03 model may be the same as the 06. This is for an 06 EX(without auto climate control) or LX. While lying on your back under the drivers side dash, look at the very top area under the dash for a 20 pin brown connector. At pin #6 there is a small yellow/black wire that goes to the rear defogger. This wire can be activated by a timed (-) output from your rs. I have my wifes Accord wired like this and it works fine. Check all wiring with a DMM.

YEs i found the heavy guage wire that come out from behind the fuse box, i tested it and yes it is infact the rear defrost wire, however it wouldnt allow me to switch it!! I used bbtaco's suggestion and it worked great!!! so thanks everyone for the suggestions!!
