Hi there (re: #11 of 13 Trailer Wiring Question by ordonez Mar 16, 2007).
I have a 2001 AWD Safari and installed my own Class III hitch, and installed my own 7-pin connector wiring. Before I answer your question, here's something else to consider.
The normal 7-pin connector and the wires that one adds themselves often "rust out" over time. Even if you load the area with TAR and keep it well protected from the elements, the wire contacts within the 7-Pin connector will eventually get shorts. For me, I visited my local RV Dealer. He sold me 15 feet to "factory molded" 7-pin connector with attached pig tail wiring. Its the same wiring they sometimes install in the back of some Pickups - for onboard campers. If you can, buy that factory molded / factory pressed pig tail wiring cabling - like I did. It's a little more expensive but near impossible the back of the 7-pin connections will rust out. Worked great for me.
To run the wiring from the van's JACK area to the outer rear bumper area, I used my air compressor and my air chissel. Using this tool, I created a hole approx 1" across. Here's the trick. Find an old "thick" garden hose approx 6 feet long and slide the 7-pin wiring pig-tail in this garden hose. Then, slide the garden hose protected wiring upwards - into the jack area. Apply a Plastic pull-tie at the top of the hole - around the garden hose. Apply a Plastic pull-tie at the bottom of the hole - around the garden hose. This stops the garden hose from sliding up/down in the hole. Using an applicator, apply tar around the top of the hole and around the bottom of the hole - from under the van. This tar stops any possible exhaust fumes coming back into the vehicle. Connect the wires, twist tie the rest of the wires, etc. All done. Some folks like using large rubber gromets but for me, I like using a large garden hose "wire sleeve" instead.
If you want, I'll take a few pictures and post them. Sometimes, a picture is worth 1,000 words. Especially when trying to explain something like this.
Hope this helps...

7-Way Adapter bought from uhaul. Is there anyone that has step by step instructions on how to install. I have a 1999 chevy astro van
Brown is Marker
DARK Green is right turn
Yellow is left turn
Large white is ground,
Should be all you need for a boat.
I checked the major trailer manufactures and no one makes an easy wiring connector for this van. Argh!
For my preivous van, I connected its 7 Pins "lights" wires to the van's rear light wires - located behind its spare tire area. These wires had to be spliced in - after confirming different wire colors with an pen light tester.
For my van's onboard brake controller, I had to install a double insulated 2 x 10 guage 12V wire under my van. One wire for its brake controller wire and its other wire for 12V "+" fused wire. For a visual of this double insulated 10 guard wire, surf: http://www.etrailer.com/p-10-2-1/Jacketed-2-Wire-10-Gauge-Brake-Wire---per-Foot.- html
Hope this helps - with your GM van....
