Just got the wiring finished up for the CB antenna and Lights on my cargo basket. You can see the hole through the roof is hidden underneath the driver roof rail. The lights have a weatherproog connector that has a dummy end on the CB antenna cable to plug into when the Basket is off so the pins are not exposed. The CB wire has another dummy end in teh roof rail to attach to as well to protech its connections too. All in all, a pretty clean job. I did all the wiring except the hole in the roof. The local Isuzu dealer did that, so if it leaks, I go back to them. I love my local dealer.
Pics are in my gallery. I just wanted to share since I had not seen this appraoch taken before here. Cheers!
