#4 of 17 Transmission Cooler by gmaster Sep 02, 2006 (11:47 am)
Anyone know if the 2007 Avalanche comes with a transmission cooler. I looked under the hood of one and it looks like it has the connections from the radiator to the tranny area, but did not get a close look. It comes with a hitch and most vehicle sold with a towing package do have the cooler. Anyone know for sure or do you have to have one installed. Also, what about a break controller?

#11 of 17 Trailer Wiring Question by ordonez Mar 16, 2007 (7:57 am)
Hello all. I have a 2004 chevy astro. Does anybody know how to run the trailer wiring from the inside jack housing to the outside and under the van? Going to install the car end trailer plug right beside the hitch but not sure how to bring the wires from inside to the ouside. Thanks.

Replying to: ordonez (Mar 16, 2007 7:57 am) I have the 7 pin connector with trailer brakes which stay inside the van until I tow the trailer. Then I open the right back door and run the wire between the 2 doors and shut the door over the wire (it does not damage the wires been doing it for 4 years now). This keeps the wire harness and connector out of the elements the 90% of the time it is not used. I don't worry about the weather corroding the connectors.

Replying to: ordonez (Mar 16, 2007 7:57 am) .   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...   .
