The first thing I purchased when I bought the van was a set of Sportscraft swivels. I finally installed them! I have no good reason why it has taken so long, but looking forward to having the functionality. While I was at it I removed the drivers side B pillar cover and ran the rear speaker wires down through the floor trays and up into the head unit. They had been stashed up above the headliner waiting for the right time. I will get to that more in a bit.
The Sportscraft seat swivels went in pretty well. They advise unbolting the base from the floor. This works fine on the passenger side as you can access the two internal front bolts from the cover in the side. Even after doing so the passenger side did not fit. I ended up drilling out the rear left corner hole to get it to go in. Luckily the driver's side one went in with the base bolted to the floor and no mods. Sometimes you get lucky!
I moved the parking break to the lower position using the provided bracket. I ended up trimming some of the plastic off the bottom of the rear part of the cover. I also had to adjust the parking break line as advised below the van. All pretty straightforward.
I am planning to continue to use the OEM head unit so I will be wiring the rear speakers into it. I can't wait to find out what the dealer charges to activate the rear faders. That may change my mind. I have been researching the best way to do this and think I have it figured it out. I reached out to someone on the forum as they had done so recently. He informed me he is a "pro builder" and basically wasn't willing to help. That said thanks to all the folks that willingly share their knowledge on this forum!
There are four open connector spots on the yellowish radio connector that should be for the rear speakers. I have seen others that buy an aftermarket Metra connector and splice the OEM wiring in. Seems like there is an easier way. I would really like to find the right crimp connector that can plug right into the open spots on the yellow OEM block. After some research I think I have figured out the right ones that should work. They are part number 967543-1 and I ordered a bunch from Mouser. I will see how they work out and report back.
I also ordered some JBL speakers and an adapter from Hein to replace the door and tweeter units up front. Hopefully this will make a drastic improvement. After I see how these all sound I may opt to add an amp.
I also ordered a Lagun table hardware set. I will be welding up a bracket to bolt in between the legs of the bench seat. Having the table and swivels should be an awesome increase in functionality. Can't wait to get out and travel after things get back to normalish.
