07 spec b seats in an 05 lgt

hi, does anyone know for sure if 07 sbec b seats (front and rear) will fit in an 05 lgt? sedan

Subscribed. I'd also like to know what newer seats with heaters fit in an 05LGT. The new ones are more comfortable and my seat now rocks half an inch or so and I'm sure it would be easier to just swap out.

Subscribed also.. I don't like the spec b alcantera interior much.. I'd rather have the perforated black leather from a regular LGT at some point. Hate to lose the memory seat though.. Would also prefer the fake wood trim to the plain silver trim.

The rear seats from an 07+ might not work on the 05/06 as the 07+have the fold down seats.

I wouldn't be worried about those as long as the front seats match the rear in terms of color. Which makes things that much more of a pain to locate the right seats. Did I also mention I don't have power seats?

*sigh*

Well ive seen at least one 05 LGT in my area who did the 07 Spec B seat conversion. i dont know who did it thou.

it can and has been done...

I've done it. Rear seats will bolt right in but you need a few extra pieces to make it work 100%. You will need the "strikers" and the trim plate for the back.

 

The front seats are a whole nother story which I'm still slowly working on. The 06+ seats have different wiring harness for the seats.

 

The Driver's side seats will bolt on, but you need to do some splicing of the power seat unit as the regular LGT does not have the same connectors as the Spec B (because of memory seat).

 

The passenger side seat is the biggest PITA, the easiest solution is if you have 05 power seats, just swap the skins, basically put the covers of the 07 seat onto the 05 power seats. If you dont do that your passenger seatbelt light will be constantly on and the airbag light will constantly say it is off. You will also have a constant seatbelt chime, which I did the "permanent disable" so I never hear any chimes (the seatbelt plug/unplug trick never worked for it). All of this because Subaru went to a new airbag unit for the 06+ cars.

 

Overall I'm happy with it while still trying to work some of the "kinks" out, hopefully I find an 05 passenger power seat soon so I can finally get them 100% perfect.

Yes I was going to add to this thread.. the 05 is dumb and has a different passenger occupancy detection system. One thing to note also is that the 06+ seats have the skins attached differently to the foam.. ie there is this piece of fabric attached to the side airbag, which I was a little weary about breaking/cutting it....

 

So:

1) Occupancy Detection system is different

2) Skins are a little different how they are attached on the inside.

3) Plugs and bolts/mounts are the same.

so, what is the issue with the wiring of the airbag system? is it a different connector on the pass side, or is it just a completely different system. I dont have power seats now, I notice there is a black male plug under each seat that is not being used, is that for the heated seats? the spec b seats have 3 wires.

Plug is the same.. detection method of the seat is completely different.. so I would assume that's why it doesn't like it!

 

The extra plug.. there should be enough for heated seats as well as power for the seats. I haven't dealt with the Spec B but the person above said it has another plug for the "memory".. er the plug is different.

it can and has been done...

personally I want folding rear seats for utility purposes

yeah I saw those threads, but neither one really gets into the occupancy detection system. What is required besides swapping the lower seat cushion. I have a good knowledge of electrical systems, so fill me in. And yes, folding seats would be awesome. Its retarded our cars dont have it. I can also get my hands on the 07 interior wiring harness.

is the detection method resistance? I would imagine its a on/off function, probably switches wires in series? IF so thats a cake walk.

from what i read you have to take the spec b's pass side seat skin and put it on your pass seat... the detection system is not the same.

But that involves pulling hog-rings and re-installing them. NOT for the faint of heart.

 

Any more specific questions or if you need a walk-through...drop me a line. Now that vacation's over...I'll be checking into the forums a little more often.

 

Also, I wrote this "How-To" just after the first of the year. It about took me forever to find it though. Might be of some help. http://legacygt.com/forums/showthrea...t=seat+install

In brief, you'll need to remove the LGT seat and take the back bolster off the seat bottom frame. then peel the upholstery/foam off of the LGT seat frame. Repeat with WRX seat. Stretch the foam/upholstery from the WRX seat onto the LGT seat frame. (This keeps the occupant detection system intact) Bolt the WRX seat back onto the LGT bottom frame (they align perectly). The side airbag in the WRX seat back had the same plug as did the LGT one...so no wire modification required.

 

Granted...it's more involved than just swapping seats; but it keeps the airbag system intact this way in case of an accident. I went WAY further than that and also installed my seat heaters into the WRX seats (salvaged from the LGT seat).

btw that was copy and pasted from a member that installed wrx sti seats but from what i gather its the same process. thats what i gather anyhow... i may be wrong

there is no way to re-work the wiring? Im trying to understand the diagnostics of how the detection system works

anyone know about this in detail

did you try to pm a couple of the members that have done it? they would def be able to help you out

I pmed them but no reply to electronic questions

patiance grasshoper, its worth the wait.

My car is going to be in the body shop for a week, Im going to just pull out the old seat, and set it next to the new one and see what this is all about.
