Ill just try to not weld around the leather.

Tx!

yes just like the mk4 seats but the bench is fixed to the bottom. they dont really fold totally flat but they are fine for me

edit

I have the wiring diagrams for the MKV seats now. once i figure them out this weekend i will post the info.

--------------
here is the limited wiring info that i have figured out

on the drivers side the connector has a thick orange wire that is a ground ( - )

the red wire with the black stripe is the positive for the recline function. possibly power for other functions but i dont know, i stopped messing around with it the min i got the seat to where i wanted it.

here is a photo of the connector

large drivers side seat plugs

here is a photo of the passenger seat plug.

large passenger connector

i have not even looked at that one yet. my library / chiltons online database does not have the newer jetta/golf wiring or repair manuals online yet. i have the bentley for the mk4 but dont want to buy one for the mk5 (if its even available) just to look at the seat wiring diagram once then never use it agian.

the yellow plug with the orange and purple wires on the passenger seat does does not provide the correct resistance for the seat belt sensor (same colors and size of the wires on my car) i am going to install the resistors as soon as the arrive in the mail. the car was throwing a low/ intermittent resistance seat belt sensor error code even when it was attached.

I also cut the wires to the seat airbag and physically cut the bag on the seat (requires you to take off the cover) so if it does randomly deploy for some reason, it will not inflate. none of that is really needed. but I feel better about it.

i sure could have used the seatheaters this morning.... this is what i woke up to... gotta figure that out asap...

Oh, I didnt even see this edit.....Thanks for the info!

Mine are set to come tomorrow AM, so Ill see what I can do too.

Of course my big goal is to not blow the bag screwing around with the electrical plugs before the seat is even in the car......

I dont understand why you have a seat belt sensor......is it connected to the airbag system somehow?

Maybe I can turn it off with Vagcom.....

if i were you i would just leave them.

I got a bunch of resistors today so if you want to use them let me know what your address is and i will send a set out to you. the resistors go into the seat harness of the mk4 and it tricks the airbag controller into thinking that the connectors are connected.

the seatbelt sensor is part of the airbag restraint system (well it might not but it DOES have a yellow connector, so i assume it is part of it) you cannot turn off the seatbelt sensors off with vagcom. you can turn off the seat airbags with vag com and i would recommend doing that. the only drawback is the airbag light flashes for about 12 seconds then goes off when you start the car. i think you would be playing with fire trying to get the bags connected.

edit..
check the wiring on the airbag harness *yellow plugs* most salvage yards will cut or disable the airbags before sending seats.

Hmm.....Ill see what comes....Thanks for the resistor offer.......Ive got a few lying around, what resistance goes in?

I was looking close at your pics....the center section of your seats has perforated leather? Mine dont.....mine are also from a Jetta, not a golf......Im thinking they might be different....

So you got both the power and the heat hooked up?

tmophoto · May 29th, 2007, 22:27

i only connected the power until i got my seat to where i wanted it. still have not conencted the heaters yet. have not had time.

resistors are
1. Connect only positives on airbag plugs with a 4.7Ohm, 1/2 watt, 5% tolerance resistors;
2. Passenger side seatbelt plug: connect with a 2.2K Ohm, 1/2 watt, 5% tolerance resistor;
3. Driver's side seatbelt plug: bundle two positives together, two negatives together. Then connect with a 470 Ohm, 1/2 watt, 5% tolerance resistor.
4. Use Vag-Com to clear codes.

Thanks for the info! Im sure it takes a lot of effort to be the first to explore into this territory.......

mannytranny · June 2nd, 2007, 08:26

Wow.........I got the fronts installed.......quite a bit of work on the first one (4 hrs) but the second one was a lot faster. I made my own brackets. The front bar, and then just two small brackets that link the rear rails of the new seat to the tops of the old roller guides. I think it gives the rear seat passengers more room......as if anyone ever sits back there.....lol

Anyway, here are the pics.......The seats are awesome. Very, very comfortable and much like a real bucket seat. I havent had the time to hook anything up either.......but the seat is reclined in a good spot, so its not a big deal for now. SES light is on, nothing is plugged in. Ill VAGcom and resist later.

Thanks again for the guidance tmophoto. Im sure ill be asking for help again on the rears.......havent even looked at them yet. Still grinning from the fronts!

Here are some pics.

If you look close, you can see a little tab that I should have cut shorter on the bracket next to the hump. Good thing is that its not very hard to remove those anchors.......Ill also trim and put back on the nice plastic covers that go over the old rail guides.

Front bracket......pry should have painted......but again, I needed the car, and its not hard to remove.

Overall!

This is a highly recommended upgrade for the:

One more question......when you connected the power for the drivers seat, how did you do it? What amperage? I dont want to fry anything......

I wonder if it would be possible to connect the power seat with the seat heater power......you might have to turn on the power seat to get power to the recline function, but that is easier than running all new power lines......? Just thinking out loud......

i just connected a wire straight from a hot fuse in the fusebox to the wire in the harness, it was connected for abut 5 min as i adjusted the seat.

got all the resistors in today, turned on all the airbags in vag-com and got no airbag light. worked like a charm. i left my harness in tact instead of bundling the wires. i needed to use 2 resisors on the drivers side, but i thought that would be better if i ever got good mk4 seats to replace these.. r32 or recaros.. then i could just plug em in. i also wrapped up the connectors so no junk would get in them.

i am going to try to figure out the wiring on the heaters this weekend if you come up with anything let me know, i have the diagrams for the mkv seats if you want them.. its still really cold here and they are a bit shocking to get into in the morning. if you did not have power seats before I dont think there is a hot wire in the harness when the ignition is on but i might be mistaken.

this is the center support for the folding rear seats part #1.

this is the black piece that holds the seats in place and screws into part #1.

ths is a pin that slides into the sides of the rear seats closest to the door

this is a hook that hooks onto the lower portion of the seat (the bench part) these dont fold forward like the mk4 seats. the bench stays flat all the time. you can see this part in the photo above. I think it might be for a carseat or something.

and you need to make or move the hooks that go on the top of the seats (where the latch is) i would not weld anythg to that sheet metal there (I cannot imagine its very strong), weld to the existing one or weld it to the frame. cut the sheet metal away, weld in the hook and then weld the sheet metal back in place, paint etc..

For all of these parts.......where did you get them?

It looks like the center support could be mated/bolted to part of the existing one. It would be nicest to have the abilty to go back to stock seats......thats kinda what I am aiming for.......

Thanks again

mannytranny · June 2nd, 2007, 13:20

Nice! I still need to do all that in order to get the airbag light off.

Thanks for the MKV diagram offer.....I might need it.

I did have heated seats before, so it seems like hooking these up shouldnt be too hard......?

tmophoto · June 2nd, 2007, 15:07

once you switch the rears there is no going back

you get them from a wrecked mkv its not easy.

t

none of your airbags will deploy if the light is on, so dont slack to hard on that one...

mannytranny · June 2nd, 2007, 15:21

Hmmm.....I am going to make brackets in order to lift the back part of the seats about an inch higher.....that way I dont have to cut anything on the bottoms. I will only have to cut the little clips that hold the tops of the seatbacks (latch).......and I am only going to drill and bolt my brackets up top.

I also found a way to just bolt in the anchors for the seat bottom.......

Thanks for the airbag tip.....I had no idea.

Ill post pix when Im done.....hopefully I wont have to do it 2x......lol
