Help me wire up my g35 seats? (schematic inside)
Okay so to get straight to the point...I have some 04 g35 seats I'm installing using all g35 rails etc. There is QUITE a wiring harness on these things..they are power and heated/airbagged etc. All I really want to do at the moment is enable them to move w/ the power controls. I assume there is a way to bypass all the other junk they have wired into these on the G-cars and just give them power/ground but I'm not the best with schematics. Any help is appreciated.
It shower power coming in at 1/8 terminals on plug b502 but I dont want to deal with the door switch and seat belt buckle switch. I dont know...

woo!! Paul always to the rescue. I appreciate it.
and no I havent tried anything yet...I figured I'd do the ask first approach for once. I was worried about that sliding limiting switch and stuff...I didnt want the thing to break if its supposed to stop itself and doesnt because I didnt wire it up properly. you know?

More than likely the motor will self-limit at the end of it's travel (just like most any other power seats).
A good idea is to search around Nissan forums, for example S13/S14, Z32, B13/B14/B15, etc for anyone that has done this swap. Their wiring setups will be very similar, and usually the 240sxforum guys are very helpful and post up all of the info.
Following that, a google of something similar to 'g35 power seat swap inurl:forum' should give you some good info.

cool cool. thanks alot. I'll report back when I get it done, I just found something on my350z that should do it for me..they are for Z seats but I cant imagine there being too big of a difference.
these seats are pretty sweet! (and heavy )

no luck. I've been trying all kinds of things. The problem is that everything goes into this seat control unit. Im ready to just hardwire the damn switch to the motor already.
#8
I'll try and help but need some time to look things over, may take a few days. Were the seat control units included with the seats? As far as your drawing goes by changing the polarity or current direction through the motor you change the direction. So you are good there. On your drawing you really need to show how you plan to provide power to the motor. You can't just hook up 12vdc permanently to both wires. 12VDC has to switch wires depending on the direction you want the motor to turn.
#9
If the seat control units were included this hook up will go a lot smoother. If not you should probably consider getting them. Sorry, just noticed, looks like you do have the control units. I'm at work so working andd trying to figure this out. You are doing the passenger side now?

thanks. damn thats what I was planning on doing (putting constant power to both wires). But I do see what your saying, the negative and positive need to switch on the motor terminals to change the direction. I dont know if thats possible using the provided switch though...unless I'm just over thinking this.
I would really prefer to just give the whole harness power as the BCM would when it plugs into the g35 and let the control unit sort out everything else, but I'm doing something wrong or not providing enough power/grounds on the right terminals.
I can hardwire power and ground straight to the motor and get it to work so I know everything is in working order.

Use the CB1 circuit breaker 1 power from your old set-up. That will interrupt current if you hit a limit. Only other signal I'm concerned abut is the speed signal is used, is this to prevent the seat from being moved while the car is moving? If so we will need to deal with that before the seats will move.
#16
your saying tie pin 1 to ground AND power?
I've already done 1,8 and 6.
I think those limit switches are only for the automatic seat movement. They are from a coupe so one of the features was that the seat would slide forward automatically if you "reclined" the seat all the way forward to allow someone to get in the rear seat.
your probably right about the speed limiter thing, I'll recheck the fsm.

if messing with the travel limiting switches can be avoided, I'll opt for that because I've moved the rails all the way forward and back and they stop on their own as far as I can tell. like I said...I am almost positive that is for the automatic seat movement feature.
#18
Sorry pin 1 of power seat sliding switch must go to ground. I'm doing this while pretending to work so it's difficult. Pin 1 of the control unit goes to 12VDC. If you look at the diagram you should be able to figure out the conections I mentioned.
#19
okay we are on a roll!!
let me start by saying that the control unit is plugged in and I am backprobing these pins, not simply putting power to the harness unplugged.
I powered terminals 1 and 8 and grounded 6 and ALSO 7. The seat started moving forward immediately..so grounding 7 was basically bypassing the switch. i dont understand why it wouldnt work with simply powering terminal 1 and grounding 8 and 6 as originally thought. I will go try one more time.
edit- pin 1 of the seat switch grounds via the seat control module, doesnt it? it shows that its tied into wire 6 on the control unit.
be right back

thanks.
I grounded pin 1 of the switch and left 1,8, and 6 connected properly on the control module with no luck. Something is not getting power. The second I ground either of the other switch terminals the seat rail moves.

Slide switch pin 6 must be connected to control unit pin #7 and Slide switch pin 5 connects to control unit pin 9.
Did the seat come with the sliding limit switch? That is grounded when the seat is fully forward.

yeah there are some little switches mounted under there which I assume are the limit switches.
sorry, what are you suggesting I do?
do you think the control unit would be restricting if it didnt get a signal from the the speed sensor or...the seat belt buckle sensor?

Try running a ground to either pin 7 or 9 of the control unit this should cause the seat to slide back and forth. If not there may be a limit switch issue. Thing is, it moved when you grounded pin 7 earlier so it sounds like nothing should stop it from moving.
Try grounding pin 9 of the CU the seat should move back.
I was just trying to make sure the slide switch is connected to the CU.

The seat may be fully forward now so grounding pin 7 of the CU won't do anything. You want to see if it will move backward by grounding pin 9 of the CU. If noting moves make sure you are still getting 12vdc at pin 1&8 of the CU and ground at pin 6 of the CU.

haha i just had my lunch time!
okay you'll return to good news. So I had no luck at first again and went and took the seat switch off the driver side and plugged it in and it WORKED! So something is wrong with the switch itself and I'm going to investigate it further.
so it turns out powering 1 and 8 and grounding 6 WAS all that was needed. It figures that some oddball thing like this occurred....I wonder if the guy who sold me the seats knew this was broken. Lets hope its a loose wire.
I'll be back about the driver seat soon as well if I cant figure it out. (it has more controls than simply fwd/reverse)I appreciate the help Nopike! (and pmohr too)

Does the passenger side have recline switch also? That should work also.

the passenger seat only has forward reverse, i dont think they bothered with the recline since its a coupe seeing as the driverside doesnt have the power recline either. The driver side has where you can adjust the angle of the back and front of the seat though. let me screen shot the schematic for that one real quick.
Yeah it is a pain in the ***...most people just bolt the cushions onto the stock maxima rails and dont bother with any of this but for various reasons I decided to try this first. I'm afraid they might sit like an INCH too high though. We'll see.

I see you got the black door panels too. looks like everything is coming along nicely.
some guy on craigslist is parting out his altima ser with black leather seats. I think his rear seats will fit your max. I see you still have the tan rears. lol

#36
thanks. yeah haha. I saw that SE-R but I didnt even want to ask about anything because I just cant spend any more money right now lol. I only bought these because I got a good deal on them ($300) otherwise I never would have. I only spend money on it when I find a really good deal. Plus I'm putting the old maxima seats in the El Camino so I killed 2 birds with one stone.
#37
The wiring diagrams you provided for the driver side are limited to signals that you won't be using, just like the passenger side. I expect making the proper power and ground connections should get you going pretty well.
#38
I'm thinking bout getting his front seats though. There black and grey and they will match my car perfect.
I say you talk to him cuz I was gona buy the motor when I was looking for a 3.5 and he was gona sell it to me for 800 with realy low miles.

and those seats will be badass! You dont even want to know how heavy these g35 seats are

Yeah the wheels are sold. Lol. I asked for them too.
He was asking 200 for the front seats. I didn't even give him a price that I would pay since I need all the money I can get for my car. If he still has them when I'm finished with my car ima offer him 125 and see what he says.
