I think the shopping experience was great. Now we will see how the shipping experience is! Thank you. I wish we could’ve had a coupon or a discount with this purchase. Maybe you could let us know if we can get one for this purchase?

Wiring harness looks good so far. Have not installed it yet. Only issue an not the fault of the seller....box torn open in shipping. But everything looks to be intact.

Exactly what I ordered in a timely manner. I'd do business again. I have already recommended to a friend.

Easy to use website and parts in stock.

Very easy shopping and good price
