Default Installing 2015 RCF seats in my 2008 ISF- need help!

So I picked up a set of RCF seats to replace my worn out ISF seats (found out its $7k to get them redone so screw that). From what I understand, the brackets are the same so bolting them in is not an issue. If they don’t match I can just cut and weld them to be in the correct spot. Or make an adapter plate

My issue is this: I need a wire diagram for the 2008 harness for the chassis side and I need a diagram for the 2015 seat so I can figure out which wires need to go where to make the motor work and the heater to work. If I can get the airbag to work to that would be awesome. I’ll probably need to wire in another circuit to make the ventilation feature work, probably just to a toggle switch and only have it set up to be off or high since they aren’t very good anyway.

I would imagine i will likely need another clip clip or something to pin together the different harnesses rather then doing a connector on each wire individually.
Any input would be helpful then maybe we can do a build thread for others that want to do this? Totally cost should be under $3.5k



-----Update-----
I have begun working on getting these retrod into the car. I have all the hardware aspects completed and will go over that now.


Both passenger seats, side by side

The RCF seat belt has a larger hole then the ISF. You can either cut and splice the ISF receiver (the wire clips are different) into the RCF harness and not modify the belt clip OR modify the clip as I will go over. My logic for modifying the belt clip was because I wanted both seats to remain as stock as possible in case I wanted to sell them.

Get 4-6 new bits because they will be ruined after 1 hole. " />7/32 drill bit to drill up to 1/4" above the hole.
Get 4-6 new bits because they will be ruined after 1 hole.

Use a steel jig saw to cut the holes out.

Grind the little notches flat
test fit, should fit just like stock

The guys in puerto Rico have done this. They are active on Facebook, but not sure if they are on here. They might be able to help you

Yea I PMd the dude and asked him how is buddy figured out the wiring. According to his profile he was active yesterday. I’m gojng to need a ISF seat side of the harness clip so I can modify that and not mess up the stock harness.

Yes, I totally planned on it. I actually was planning on making some harness adapters to sell for others that want to do this.

RC F and GS F seats suck compared to IS F seats. I have both and drive them routinely - the wife (8 months pregnant) asked me to drive the IS to Nashville from Atlanta instead of the GS because the seats are so much more comfortable and supportive. Best of luck with your swap, I would not do it.

I have an RCF too and find those seats much more comfortable then my worn out ISF seats. The ISF seats aren't bolstered as well so I slide around a lot during spirited driving, not to mention they don't have good lower back support. I can see why your wife would have preferred the IS over the GSF, being 8 months prego (congratulations!) would defiantly be a reason to want less bolstering. My lady actually agrees too but hey, thats why she has her own car lol

I plan on keeping my ISF seats and making an adapter harness so I can easily swap between to 2 if I needed to for whatever reason.

lol thats pretty much the bulk of it. The wiring info can be provided by one of the members on here. I'd post it but I don't think they would appreciate it since it took a long time for them to figure it out so they are trying to make a little money in the process.

Hey, looking good.

Out of interest, how do the RCF seats compare to your old ISF seats in terms of weight?

Guessing they are probably about the same, but curious to know.....

Cheers,


Pete

Did you rewire the car so that it can also use the ventilated seat option?

No, the guys who figured out the wiring in the first place are still working on getting that working.

I though it would be easy to just have the Heat and Cool features on two single switches with both on max instead of the 3 levels since 1 and 2 are next to useless in these cars lol.
This would require us to completely bypass the existing switches ETC

What if you used the heat/vent controls from a 250/350? I have tons of spares I could send you to test it
