Just purchased an overhead DVD unit from Ebay...would like to mount it just behind overhead console right over the dome light for the grandson in the back. Anyone else do this? It appears there is plenty of room to do it but was wondering about the wireing...it has built in dome light that I will just connect to the old dome wires...what I am wondering is...do I have to fish new power wires thru the console or headliner or are thier power wires already up there? Should mention I have 2001 Silverado w/4 dr & 5.3l
