Replying to: zadriel (Sep 27, 2008 1:35 pm) I can't seem to find my previous post / reply. Thus, here's the same info about installing a Class III hitch and its wiring for onboard Brake Controller. For video - to install the Class III hitch: http://www.sutree.com/game.aspx?s=38711 For factory 4 pin Wire connector on RDV vehicle, puchase: http://www.autoaccessconnect.com/re2020trwiki.html Note: Factory V92 plug under the rear right bumper area. Simply remove its blue plug and "plug in" the new V92 trailer wiring adaptor cable. Surf above URL for a picture. If wondering, I connected the "brown - running / clearance" and "white - ground" wires from this bundle to my customized rear ID bar (3 lights). For a trailer with onboard electric brakes, puchase a 7-pin connector and mount this connector under the vehicle's rear bumper. Many need to buy its galvanized steel mounting plate as well. For a picture of this 7-pin connector, surf: http://www.etrailer.com/p-30310.htm Note: Double check the "connector" on your existing trailer (that has its own onboard brakes). It may have a 6 pin connector or a 7-pin connector with round holes. Thus, a slightly different rear connector may have to be bought. For now, let's assume your trailer needs a 7-pin connector with blade contacts (that's shown in the above URL). Using the 4 pin leads from your factory V92 "pig tail" and installed 7-pin connector (mounted under rear bumper area), connect the available wires together. Use a scratch pad and 12V tester to ensure each wire (and ground) is properly connected. For picture of what wire into 7-pin plug, surf: http://www.etrailer.com/Merchant2/graphics/00000001/faq/wiring_7_pole_500.jpg The next steps should be done by a 12V auto specialist. For me (on my other vehicle - which is our tow vehicle with Brake Controller), I "pulled in" the 10 guage wiring but got my auto mechanic to connect their ends. Using 2 x 10 guage 12V wiring (one blue and one red - for example), connect to your 7-pin connector and pull these wires to the front of your vehicle. For my other vehicle, I pulled / fastened these wires on the outside (under the vehicle). If you like removing interior panels and such, run these thick 10 guage wires on the inside. If wondering, 1 wire (for example, RED wire) goes from the vehicle's "accessory" fuse to your 7-pin connector - pin #4. When your vehicle's ignition key is ON, this pin #4 is live. If wondering, pin #4 is often used to "trickle charge" a 12V battery inside the attached trailer (assuming the attached trailer has on onboard 12V battery). When the vehicle's key if OFF, there's NO current down this #4 wire. The other 10 guage wire (re: blue wire) that was installed goes from 7-pin connector Pin #2 (electric brakes) to the vehicle's onboard brake controller. For pin assignments within 7 pin connector, surf: http://www.tropictrailer.com/images/wiring/image013.jpg For more brake controller wiring details, surf 1/3 page down: http://www.etrailer.com/faq_brakecontroller.aspx Fully test all signals, running / clearance lights, brake controller pin #2 and 12V live pin #4. If necessary, do replace the vehicle's factory default load "flasher unit" with a HD (Heavy Duty) Flasher unit as well. Thus, stopping your flasher from flashing too fast (when towing a trailer). One of those "try it and see how fast it flashes for you" things. Note: After wiring is fully tested, use "plastic cable loom" to protect the rear wires and use galvanized strapping to secure the wire loom bundle. External silicone the back of the 7-pin connector as well. Thus, keeping crud and rust out of this critical connector. Also... Mount the 7-pin connector on the vehicle's rear bumper. Do NOT drill holes within the installed trailer hitch. Extra holes weaken a hitch. BTW: To connect a standard 4-pin trailer to your newly installed 7-pin connector (say a small utility trailer without brakes), simply install a 7-4 pin connector. For a picture, surf: http://www.northerntool.com/webapp/wcs/stores/servlet/product_6970_200336745_200- 336745 Hope this helps... . |

Replying to: zadriel (Sep 27, 2008 1:35 pm) The V92 plug (for trailer wiring harness) is located under the "left" rear bumper area. For more pictures of how I installed the ID bar, its V92 location, plastic loom and PL Premium (for water protection) coating, surf contents of: http://s178.photobucket.com/albums/w251/Spike99-Pictures/RDV%20Rear%20Lights/ Note: To enlarge each thumbnail picture, simply click on it. Hope this correction and more pictures helps as well.... . |

Replying to: spike99 (Sep 28, 2008 7:16 am) Perhaps you could tell us more clearly if you used the following... DRIVERSIDE or PASSENGERSIDE. I've looked at the photos and they appear to be passengerside rear bumper area if the tire placement and laying under the car are taken into account. However, looking under MY rendezvous I see a pigtail just hanging loose under the DRIVER side back of the wheel well area. The other part of this continues up into the back and I assume eventually the rear driverside light. Please help us to konw what we are looking at in the photos... were they driver or passenger side shots? I also am unable to tell exactly what you did with the four wire plug that you purchased. Let me restate it, I'm looking ofr a simple way to plug in and have lights to a four pin camper plug. I'd rather just connect one plug if thats possible. |

Replying to: spike99 (Sep 28, 2008 7:16 am) The V92 outlet is under the rear bumper area - driver's side. To connect a utility trailer that does NOT have its own onboard electric brakes, simply install a Class III hitch (as shown in the video). Then, buy the V92 to 4-pin Flat connector (which is approx 2.5 ft long). Connect the V92 plug into the vehicle's V92 outlet. Plug the other end of the wire (which is a 4 flat end) to your utility trailer. If you pull a tent trailer or utility trailer that has its own onboard electric brakes, then install a 7-pin connector instead. Install a Brake Controller in your RDV. And if your trailer has onboard battery (like tent trailers), then install a 12V "live" wire as well. If only pulling a light weight utility trailer that has Surge Brakes or NO onboard electric brakes, simply purchase the V92 to 4-pin wire. ---------- For video - to install the Class III hitch: http://www.sutree.com/game.aspx?s=38711 For factory V92 to 4 pin Wire connector on RDV vehicle, puchase: http://www.autoaccessconnect.com/re2020trwiki.html Note: Factory V92 plug under the rear right bumper area. Simply remove its blue plug and "plug in" the new V92 trailer wiring adaptor cable. Surf above URL for a picture. If wondering, I connected the "brown - running / clearance" and "white - ground" wires from this bundle to my customized rear ID bar (3 lights). Forgot to mention... I do NOT tow anything with my RDV. My mechanic tells me that my 2003 RDV FWD isn't made for towing. Yes. I have a Class II trailer hitch for my RDV (which is hanging in my shed) but did NOT install it. For towing (even light weight utility trailers), I use my other vehicle - which is made for towing. My RDV's V92 to 4-pin 2.5 long wire harness was modified to connect into my vehicle's custom ID "light bar" instead. For this, I simply cut its 4-pin flat connector off and spliced its brown (running lights) and white (ground) wire into its ID light bar. Its green and yellow wire in this wire harness 2.5 long bundle were left "as is". Hope this helps as well... .

Replying to: cruzak (Apr 19, 2009 3:09 am) For a "light weight" utility trailer of say "1700 lbs gross wt.", your 2005 AWD RDV should easily pull it. And pull it without too much stress. If wondering, my one utility trailer has a 3,200 lbs axle and my other vehicle has a 3,600 lbs axle. Thus, I use a differt vehicle (my non - RDV vehicle) to pull either of my utility trailers. Thus, allowing my RDV to remain a "run about" vehicle. For your 2005 RDV, pulling a utility trailer of "1700 lbs gross wt." is very little stress on it. If you pull a "loaded" utility trailer WITH rear cargo and/or WITH lots of passengers, I'd recommend installing an Aux Transmission Cooler as well. Thus, keeping its tranmission oil "cool". Cool = longer transmission life. For example: http://www.makcotransmissionparts.com/OC-1678.html And if the rear of your vehicle has too much rear sag, you might want to investigate Timbrens or Air Bag suspension upgrade as well. re: http://www.timbren.com/timbren-application-guides/application-pdfs/GMRREN.pdf As long as you pull a light weight utility trailer and don't over "push it" during stop/go traffic, against strong head wind and/or up the steep hills, your 2005 RDV should easily pull a max loaded 1,700 lbs utility trailer. . |
