Feature: This is the ONLY harness that corrects the original problem!

This harness has been updated to address the failures in the original (OEM) harness and previous versions of the AC Delco PT2195 pigtail and GM 15862656 pigtail. All wire gauge sizes have been upgraded to easily handle the current demands of the Blower Motor at all speeds. Heavy duty 12 ga. wires for the 12v power, ground (-) and the high blower circuit.

Harness is color coded to match the original vehicle wiring (there may be exceptions to this depending on the year and make or your vehicle). Included are free Sealed Splice Connectors (Heat Shrink Butt Connectors) for easy installation.

If you prefer, you can solder the connections and then use a quality 2:1 or 3:1 epoxy heat shrink to cover the connections.

Installation Instructions

Easy Installation Instructions from buyWiring:

Installing our pigtail harness is a snap! Use the color codes to distinguish which wire goes where. These installation instructions will guide you through the installation process whether you're an amateur hobbyist, occasional home mechanic, or professional automotive technician. If you've never done it before, here's how it's done in a simple step by step process. Say goodbye to low quality replacement harnesses and while you're at it, say goodbye to ever replacing a 7 wire blower motor resistor harness made by buyWiring.

  1. Cut original vehicle harness and connector kit wires in a staggered fashion to eliminate the stacking of splices.
  2. Strip 3/8 inch insulation from end of each wire to be connected. Be careful not to cut any of the wire strands.
  3. Connect wire(s) together with the provided sealed splice connector(s)

Wire Color Reference Table

Harness Wire Connects To
A - Tan Medium 1
B - Yellow Low
C - Purple Medium 3
D - Lt Blue Medium 2
E - Black Ground (-) Negative
F - Orange High to High Blower Relay Coil
G - Red Battery (+) Positive Feed


Make sure to connect the wires to the same position they were on the original harness (see Reference above).

Sealed Splice Instructions:

  1. Position stripped ends of wire into splice connector until wire stops.
  2. Hand crimp each side of the splice connector using an approved crimping tool (P/N 12085115). Gently tug on the wires to ensure that they are securely crimped.
  3. Apply heat to the outer shrink tubing of the butt connector until it seals against the wire. Use a heat gun or Ultra Torch P/N 12085116. A small amount of epoxy should flow from the ends of the shrink tubing when heated properly.


Do not use any open flame!

This part was well worth the wait! much better quality than the ones offered at the local parts stores (or the same price). it comers with everything you need including the heat shrink. And they were spot on as to which wire was most likely bad if you wanted to bypass the ground wire to get your system back up and working while you wait in the part.. Great job all around.

Arrived just in time. My Delco replacement stopped working same day. 20 degrees. Very well made. Much better wire than OEM or the Delco replacement that also melted. This is what should have been installed in the first place. have checked it after driving with heat on full and no sign of heat in the wires. Time will tell. Glad I found this product. Colored wires made install very quick 20 mins.

My son and I had problems getting our a/c blower motor to run on our 2006 silverado, and found the resistor harness burned out.Checked the internet and found Buywiring had what we researched was the best product available. The wiring was much heavier and as we found out after installation, would carry the max current with no heat generated at the plug. We want to thank buywiring for doing a great job of engineering in their wiring harness.

I bought the product on the 27th of December because my wife's front vents in her trailblazer were not working. No speeds 1-5. I received the part 3 days later (really fast shipping). The part also came with instructions and heat shrink to use on the wires. After about an hr of work everything was hooked up. The moment of truth. I turned on her vents and they started blowing. Every setting from 1-5. Thanks!
