Backup lights

I am interested in wireing my headlamps and my backup lights to the same aux channel of my keyless entry system. If anybody knows where the backup lights wiring is located, I would appreciate any assistance. Also, is the best way to do this with two seperate relays? Thanks! 

Not a pro, but heres what I'd do. 2 seperate relays. I would look in the trunk and note the color of the bu lamp wire then look for it in the door sills, if I cant find it I'd just run a new wire to the trunk. If the bu lamp fuse is by itself (doesn't supply anything else) you could tap into it there.

should be light green at ing switch
