I have an 01 QC 4x4 with completely manual everything and rubber floor mats. My drivers seat outer bolster seam is shot and it is breaking down plus there are a couple of tears and some staining. Well a very nice complete set with power drivers seat. Supposed to be an easy swap and physically it was but I dont have the right wiring diagram and apparently you cant just swap them in and leave them without hooking them up. Inluded was a seat belt module but th eguy cut up some of the wiring and of course it doesn't come close to plugging into the pigtail on the floor from my manual seat.

So my question is in regards to the wiring of the seatbelt module and how it interfaces with the seats. Are there wiring diagrams posted anywhere? Is this even a doable swap since I didnt have power to start with? Also, it SEEMED as though the passenger's seat sat much higher in the new seats than the old, and not due to the old one being broken down, are there more differences than I was aware of?

thanks for any insights you may have

 

An oem service manual would probably help you get the wiring figured out.

 

Tryinng to tie into the factory wiring, that probably isn't there will be a problem, because without power from the factory all the electronics, including the connectors in the fuse box won't be there.

I would use relays and new wiring to wire them directly to a power source, ie the battery.

Your 01 quad should already have the seat belt module under the middle seat, huh?

 

Thanks guys

Yes, i probably should get a FSM, I do have an electronic copy I think but my computer doesnt see discs anymore. I need to deal with that too and see if the necessary wiring diagrams are there

nothing under the front middle seat up in the cab, I didnt crawl under to check, the new one that came with the new seats didnt look like a weather proof unit. Mine is sort of abnormal though, the VIN says it's an SLT but it has no power locks, windows or anything else and has rubber floor mats rather than carpet. I had the cab empty and scrubbed the floor mats before figuring out that I wasnt going to get it swapped in an afternoon.

Thanks, more research is required

 

It could have been a special order truck with deleted options, not that uncommon.

However, if it has airbags and SRS it should have that box under the seat, IIRC its the inertia trigger to the airbags. Dodge trucks don't have bumper impact sensors like the Chevy's do.

 

Well I'm sure it was a special order as it apparently shows an SLT by VIN but is rubber floor mats and no power accessories. Seems to have airbags in the steering wheel/dash and the passenger side lock out switch. It was originally a power utility supervisor's truck

I had the seats and console out entirely and scrubbed down the matting and found no box, I assume it would be there under one of the seats or the console? The seat belts in the factory seats work like any others in that they pull out slowly but lock in place if pulled suddenly, the 'new' seats do not release and pull out at all at this point, I assume they do when the box is attached but I will have to figure out the wiring and hook it all up to confirm.

I downloaded a FSM but I havent found the right wiring diagram and the description regarding the seats was not helpful, perhaps I need to look more at the airbag section or see if there is something more specific to seatbelts than what I was able to find initially (It's 1298 pages!)

Thanks for the help, learning more everyday...

 

It's mounted to the frame under the center seat/ console nit on the floor

 

thanks, I'll pull the console back out and look again, I sure didnt find it when I had it out before but must have missed it.

Where does it get power? the only harness under the entire front seat assembly was a two wire plug that plugged into the drivers seat. Still confused about the seat belts not releasing when sitting on the floor on th enew set and working freely on the old set.... who knew swapping seats would be so complicated, at least for me

Thanks guys!

 

Trust, you don't say what year your new seats are, so it is harder for us to offer accurate advice.

I can say this though. In 98 and 99 they put the seat belt control box between the seats, hung under the console. In 2000 they changed the design so that module was no longer there. Apparently it is contained within the seats. When I bought new seats for my 96 I went through this, as I got seats from a 98. I had to wire the module to power when the key came on to release the seat belts, and I should also have it wired to power up when I open the door, again to release the seat belts, but I never bothered with that.

For newer seats, I checked into it, and I believe that you just ran power to the seat itself, but I cannot remember if a wire went between the seats to power both or if they got separate power for the seat belt control. The seat belt control is a different power wire than the power for adjusting the seats in the 98-99 seats, but may be the same for the newer ones.

Do you know the year of the seats you want to swap in?

My leather seats came out of an '01 and the module is under the middle where they always have been, a friend put my original seats in a first gen hooked up power to them, seatbelts and powere adjust work fine, with a schematic should be easy to figure out, on a side note my new seats were plug and play in my '98

 

Thanks , unfortunately I dont know specifically, I'll try to call the guy i got them from and see if he knows, he was going to put them in a 89 regular cab and decided against it. I currently have a 2 wire harness coming through the floor to the drivers seat, that's the only wiring on my seats that I have found, nothing between the seats and console, nothing else coming through the floor but I need to take the console back out and look under it to be sure I didnt miss it. Even so, it doesnt have a source voltage to plug into coming through the floor.

I down loaded the 01 FSM, all 2889 pages, and thus far have not found a wiring diagram for the seat belt control module, but I am still digging.

Thanks for the help,

 

Here are some threads from when I was messing with the seat belts.

Apparently I had the wiring info at one time. I'll have to look and see if I still have it.

OK, here's how mine are wired.
Constant 12v:
Red, Lt Blue stripe,
Pink.

Ground:
Green Red stripe,
Black pink stripe.

Separately wired from the ignition, and is also supposed to be wired to the door switches: Blue.
Mine is only wired to ignition, so the seat belts won't release to put them on until you turn on the ignition.

I think the timer is part of or connected to the TIPM, which I can't remember what that stands for. At work I'll on Alldata.

 

Thanks gents! I think we're getting close here. My 01 does not have the box, I checked again under the console, under the seats and under the truck where the wiring harness that goes to the seatbelt indicator switch is. No sign of one at all. Seems to jive with the first thread Stamey posted. So apparently the new seats are pre 2000 and need the box unless I disassemble them and change out the retractors.

The wiring I do have has the box with harness, 9 pins per end with the Orange with Red trace and Orange with Black trace cut. The other end has the Black with green trace, the Red with Blue trace and the Green with Red trace cut. There is also a 3 pin connector that has a green with red trace and orange with black trace and a black with green trace and a 2 pin connector with a Black with Green trace and an Orange with Red trace.

I assume that the three ends of black with green trace (box plug and both 2 and 3 pin connectors) are tied together(?) The Orange with red from the box and the 2 pin are tied together (?) and the Orange with Black from the box and the 3 pin tie together(?). That leaves the Green with Red from the 3 pin, the Black with Green, the Red with Blue and the Green with Red from the other 9 pin connector.

Since there is no harness in the truck the one 9 pin has nothing to connect to. Based on what Stamey provided it looks like I need two 12v and 2 grounds, the rest are ????? one wrinkle is that the Red with Blue in this connector doesnt go anywhere, it's been cut and there is no Red w Blue going into the box. There is a red with blue and a black with green going to the drivers seat but that pair has no connector. The passenger seat has a pair that matches the 2 pin connector described above.

That leaves me with the one 9 pin and the 3 pin with nothing to plug into and the two conductor coming through the floor for the original seat.

I have no idea if hooking this all up with do more than allow the seatbelts to work. Does the power seat function have a different controller or is that what the red with blue and black with green do for me?

Also, you mention (Stamey) that it should be constant 12vdc, shouldnt it be switched 12vdc or does it need to be powered up constantly?

Sorry to make this so darn painful, I'm tempted to try and recoup the $ and live with the broken down stocker but I doubt I will come close without getting the basic wiring restored.

Thanks again for the help, more will be GREATLY appreciated....
