Dorman 600-600 - Arnés de cableado de actuador 4WD compatible con modelos seleccionados Chevrolet/GMC

Real easy install.. Was an upgrade to the old thermal actuator , so had to install new wiring harness as well . Works great so far ..

Works great, very easy install

Update: today was about 40 or so degrees out, the sun was shining and the snow was melting, so naturally there would be puddles of water on the roadway. I hit one such puddle today, and it caused the electronic actuator to short out and try to engage 4wd while I was going about 30 mph in 2hi. Now the actuator wont engage at all, but the 4wd light is illuminated.Hey Dorman!? Whats the lifetime warranty say about puddles?? Not sure what to do here.Purchased with the mechanical actuator for a retrofit on a 92 k 1500. So far it works like a charm. Plug and play with the existing two prong connector to the actuator, and one simple connection to key on power. No splice needed. Those wire taps are a problem waiting to happen. Had enough length to do the job and then some. (That's what she said)I was lucky and had a hole in the firewall right behind the parking brake where it needed to be, it was a snap to connect to a key-on-power...It even had a grommet so as to reduce the likelihood of a short.I was able to route the harness far enough away from (I hope) the heat of the exhaust and the spinning shafts that would snatch a wayward wire away.Will update if anything noteworthy occurs.

Update: This harness and actuator are still working flawlessly on my 93 K1500 in Minnesota weather. I have had them installed for the past 4 years and they are still the best $100 investment I have made.Great product and along with the actuator (600-101) it is well worth the price. I am sure you could build this harness yourself for half the price but overall it is plug and play which has to be worth something as far as convenience goes. The actuator seems a little mickey mouse being that it is all plastic but supposedly these things last longer and are more reliable than the junk thermal unit that you are replacing. The picture of the actuator shows some pipe sealing tape on the threads but mine didn't come with any on it so I added some of my own. Figured it couldn't hurt. The most important thing I can tell you is that when you get to the part of the instructions where they have you splicing the extra brown wire in this harness into an existing wire under your truck, do yourself a favor and throw the instructions away or better yet use them as fire starter. Rather than making a splice under your truck in a very difficult location that is exposed to the elements and is likely to corrode, make your connection inside of your truck cab. If you do this, you do not need to make a splice into another wire, you can make your power connection in an open slot in the "convenience center" located under your dash just behind the parking brake foot lever. I have read other reviews where guys have done this and made their connection at the middle spade of the slot called "DRK GRN". Well, my 1993 K1500 doesn't have a slot called DRK GRN with three terminals in it (neither does my buddy's 1994). If your truck does, congratulations!, you can make your connection there. In my case, I used a voltage meter to find a terminal in the convenience center that has 12V ONLY when the key is in the run position. If you don't have a volt meter handy, I'll make it very easy for you. On the right side of the panel, approximately half way up, there is a brown wire with a white connector plugged in. The next terminal to the left should be open (at least it was on my truck), make your connection there. Use a female spade connector and plug the brown wire from your new harness into the terminal. This is a small pin connection but a female spade connector will still work. Just as an FYI, the brown wire with white connector right next door is the same wire that the instructions want you to splice into under your truck. Both of these terminals in the convenience center are on the same circuit. At the end of the day, any terminal in the panel that has 12V when the key is turned on will work.If you are efficient with your wire routing, there is just enough wire to get to the convenience center. I made my penetration through the firewall with a 1/4" drill bit just above where the hood release cable goes through. I also installed a small rubber grommet to prevent wire chaffing which I would recommend you do as well. My 4X4 now engages almost instantly (major improvement)! Best hundred bucks I have ever spent.As a side note, don't bother trying to talk with dorman customer service, they have no clue what they are talking about.This has been a long review with a lot of information in it but I hope it helps you guys. I know this is the review I wish I had before I did the job. Total install is less than an hour. Routing and zip tying the brown wire is what takes the most time. Second pair of hands/eyes would have made the job go faster as well.Good luck!

Use this wiring harness with the 600-101 actuator to update your 95-2000 chevy truck to the newer style front axle shifter. The new 600-101 actuator shifts in a few seconds rather than waiting while the old thermal actuator struggles to shift. Here is a tip from another reviewer that I used also. You can easily connect the third brown wire (power source) to a terminal block located INSIDE your vehicle. It is down low by the parking brake pedal. Look for the lower middle terminal called DRK GRN. The middle wire of the three located on the DRK GRN male connector is powered from the 4 wheel drive circuit, which is the one you want. I drilled a small hole in the driver's side firewall, and then ran the wire along other wires on the driver's side and then around the front of the engine (in the red battery wire channel over the radiator) to the passenger side, along the frame which is where this wiring harness comes off the front axle. Use Dorman Gold plated Female disconnects part # 84547, 16-14 gauge to connect this wire to the terminal block inside the vehicle. These #84547 disconnects will fit on the middle spade of the DRK GRN plug at the bottom by the parking brake. Good luck and enjoy much faster/easier shifting into 4WD!
