This connector serves multiple applications and is also used as an A/C compressor connector, engine coolant temperature (ECT) sensor connector, engine cooling fan switch connector, and engine shutdown switch harness connector, making it a versatile pigtail for a wide range of GM-platform electrical repairs.

Out of all the websites I've used to find my item, this was the lowest cost, and I'm so happy that I found them! Keep up the great work guys!

I was a first time customer, but will definitely visit Autoplicity.com again! Great prices, and fast shipping! Thanks!!

Great Price for the struts i ordered!

Fantastic service and fast shipping! Lowest price on the net for the CAI that I bought!<br><br>This is my new "Go To" website for parts.<br><br>Thanks!

By the time you add in shipping, even the "Rock" can't compare! Thanks!

Good customer service!!! I ordered a greddy boost controller. Took for ever but they explained why.. And everything is all good!!

Best price on a holley carburetor online. I unusually use summit but even the shipping price is less, no handling fees either. I am hearing great things about the shipping so I am hopeful the 69 javelin is back on the road this week! If it works out I will tell all my motor head friends about this site!

The correct product that I ordered, and easy to find through there web site.thanks
