Looks like a blazer tank should fit. The 4 pin connector and the insert came with the hitch. I thought it was a pretty good deal as the kit. There was just enough room between the plate cradle and the hich for the wires. I was concerned about getting to the hitch pin, but works really well. I added the 7 pin because I have a 5 pin on my boat and I have a 7 to 5 adapter. Liked having the 4 pin there also for a small trailer I have. I'm getting excited, after 7 years owning the truck I'm finnally making some headway.
