C8 Seat Installation Guide into a C5

Just to be fair-- Dan@vetteworks makes some quality products -- but oversells their capabilities. He promised me -- in email and text -- that his c5->c7 adapter would enable telescoping steering. When I called him out on it, explaining to him that it didn't work and suggested a possible fix, he emailed me and said he "didn't have the time" to do it, since his shark bar was taking way too much time. To this day, I don't think his website clarifies that his adapter will not enable telescoping steering. It also took around eight months for me to get a non-working adapter from Dan.
As for that video-- as you pointed out, you can't buy the adapter he references from dan's website -- that should tell you pretty much all you need to know. And allegedly dan has said to the poster that he "could" enable seat memory, but we have yet to see that functionality-- from any vendor.
If you buy anything from vetteworks, ask LOTs of questions, and do it through email so you have everything in writing.
I would suggest just looking at the guides that have been posted here -- it's super easy to wire in an adapter, no need to go through the aggravation and time of going through a vendor. And it's far more satisfying to do it yourself than pay someone to do it for you.

Thank you for this picture. I have the GT2 seats and this was exactly what I needed. All of the other endless threads were very confusing. So anyone else that is looking for wiring info, disregard everything else and go directly to this picture.
That said, I'm using quick connects to the pins but I get the feeling that it's not a good long term solution as they can pull out fairly easily. I'd recommend splicing into the wiring behind the harness (now that you know what pins to look for) or maybe soldering direct to the pin.

Delay on first use?
Hey guys, mine are working well in the c6, with same wiring list above.
Only thing I’ve noticed is that my seat always ‘stalls’ on first use, almost like I have to wake it up. Basically, when I get in the car and move the seat, it moves a tiny bit, then stops. Then I have to lift off what ever direction I was going and then try again, the second time it works fine.
Anyone else have this issue?

yes, cut off what I couldn't unbolt. I may have started with a angle grinder cut off wheel, or I may have gone straight to a dremel type tool with a small cut off wheel on it, can't remember exactly.
I then made a template out of paper to get the outline I needed for the cover plate, then tranfered that to a piece of xPVC. Then while wearing work gloves, used a heat gun to soften up the xPVC and contoured it to the seat. Covered that in black leather, then used upholstery contact adhesive to glue it to the seat back. The side of the seat was up against the door plllar, so hardy visible.

I wanted to remove the side airbags and brackets. You have to remove the upper seat leather & cushion to get the seat back off to access the bolts on the airbag bracket... I decided to cut off the bracket.
I first tried using a dremel metal cutoff, which doesnt have the radius to get deep enough for the whole bracket. I tried trimming the seat back away some, but had use my 4.5" angle grinder anyway.
If I did this again I would use the 4.5 grinder from the start, make a clean cut along the red line in the pic below and be done with it. The slice into the seatback can be concealed by the covering you create.
Also, I cut away some of the protruding metal bracket for easier maneuverability with the grinder.

subbed to this thread. ive seen Rods car at our local track and its looks and feels (sat in didn't drive) amazing. love them. I am currently looking for a matching set of either gt2 or comp seats for wifes 99 C5 mn6. Thank You to all who have documented your install details.
On topic: the gt2 seat side bolsters are amazingly solid on track and really let you lean into them. I could feel zero flex in the seats, they are a huge improvement over the c5 (and c6) seats.
I used to track my c5z years ago and I still remember stuffing foam behind the seat back at the track and saying a Hail Mary to hopefully stop the seat back from flipping back in the middle of a lap! Not fun when that happens!

Glad you liked them! Hope we get more vette’s out there, was a blast following your ZR-1 around for a few laps!

I did the same welding and similar sheetmetal bracketry that Rod showed previously (many thanks, this was a HUGE help) Happy to have the airbag functionality using the original C6 parts. I wound up installing an accessory fuse block controlled by a relay to power my passenger seat, and I also used this to bring power to the seat fans separately. For the drivers seat, I got new pins for the original C6 seat connector and brought power to the C8 seat through that. I dont have a great pics of this but can track down the part #s etc if anyone is interested. I used Amphenol connectors everywhere else which keeps things clean and somewhat professional looking... it allows you to disconnect everything easily if necessary.
BTW this project started as an MGW shifter install, and quickly morphed into sound deadening, head unit/amp/speaker upgrade, seat upgrade, and raptor shift light install. If it's all apart, why not??!! Well worth the effort. Really enjoying the car and the convenience and comfort features have made it that much better.

Hey @Tim90NOS ,
I dug into the fan install this weekend. One question for you…. Did you get the seat back fans to work as well? I tapped into the red wire as you describe, but only my seat bottom fans come on. Not the back rest. Not sure if I have a problem with my seat or if there is another wire I need to connect as well. Let me know your experience.
Edit: I see now you mentioned there are TWO connections under the seat, one for seat and one for back. I should have read more carefully! Thanks again for the details!
Thanks.
Rod

I was finally able to get the fans working. Pulled the seat covers back to expose the fans and heating element, the fans have Black/Red/Blue wires running to them. I traced the wires back to the brown connector on the seat bottom, applied 12v and nothing happened. Dug around some more and found this relay (?) between the brown connector and the seat bottom. I put 12v to the red wire, negative on the black and woooooooosh the fans turns right on!
FYI I'm not pursuing the heated seat function, but it seems the gray connector next to the brown goes to the heating elements.
Brown connector with yellow, black, and white wires. There are two of these on each seat, one for seat bottom, one for seat back.
Cover pulled back exposing heating elements
fan lives under here, can make out the red/black/blue wires
This is the square relay/control fed by the brown connector.
this is what is under the tape
I exposed the red, black, and blue wires. Put 12v on red, and negative on black and the fans come to life! I believe the blue wire is FG (frequency generator signal) from the fan that communicates whether it's locked or running... leaving this alone for my purposes.

Has anyone figured out a good way to cover the side air bag "holes"?
BTW I considered wiring for "low" and "high" seat fan speeds, and I'm glad I didnt go to the extra effort. "High" or 12v direct is the only speed I need.
All of the C6 SRS components I swapped over are functioning (knock on wood). Huge thanks to @_Rod_ for your work on this.

Hi Tim,
Wow, that must have been some trip!
Yes, I am loving the seats. My car is 75% track at the moment and these seats are amazing at holding in the upper body. The lower bolsters are never going to be confused with a race seat, but that is where I wouldn't want to give up the comfort in any case.
Really nice to have the air flow on the seat, I pretty much keep it turned on all the time/now that summer is in full swing.
My airbags are still 100% intact, so I don't have any holes to worry about.
Cheers,
Rod

Has there been any further advancement on function controls, specific relays to use, perhaps aftermarket adapters, etc?
Are the cooling and heating functions a basic on/off in the C8 and in the conversion, or do they have multiple settings like most new cars and have the conversions identified the correct signal to control this if so?

I saw this posted on FB for C7 heated and cooled in C6, perhaps they can do the C8 seats as well: https://melochedesign.com/collections/all
If you search youtube for bonecrrusherss "C7 Competition Seat Vent Wiring" he shows how to add a resistor for multispeed fan. I considered this, but went with an on/off switch and have no regrets.
Good luck, let us know what you find.
