I just picked up a set of leather lariat seats from a 2004. They are full power and both sides are heated. I have a 1999 f350 and only the drivers side is power. I figure that I will need the wiring harnes for the pass. side but will the heating elements work with my current plug or will the drivers side need to be swapped out also.
How should I go about swapping everything out and getting the new seats to function properly?

Thanks
Bubba

 

I got done installing the rear bench. the middle jump seat and passsanger side but the drivers side plug is different. Do they make any type of adaptor to go from my small plug to the larger one on the heated style seat.
Also does anyone know how to move the seat back with no power to it. The drivers sear is pushed ay forward to the point wear I almost can't drive it I'm so close

Thanks
bubba

 

you can do a quick wire with a jump box or batery an just tap the conections to make the seat go forward or reverse in your case. as for the wiring convertor i dont know.

 

Thanks big bee I will try that.
Also I technically still have access to the truck they came out of. It is a totalled truck so I can get the wiring harness still but I would imagine pulling them all the way is probably more effort than it is worth.
Any other help on the harnesses?

 

You'll need to lookup the wiring diagram for the 04 to find the right pins to ground and apply pos. 12v to to get the seat to move back. Any other method would most likely require to much disassembly. Once you have the wiring diagram for the 04 you would just need the connectors that connect to the seat from a donor rig. You could use some other items such as circuit breakers, wiring to reach under dash, and other minor items to finish it out. Be sure to fuse the power to the seats(heaters & motors).Separate would be the best way to have some function in the event any load problems arise.
The wiring diagrams aren't alot of peoples cup o tea, but given some study, can really answer most of your questions.
I don't know of any adapters for your old to new situation. The best bet for me would be to utilize the leads from the 04, coming out from under the carpet. Get them and then study your trucks wiring to splice into that units leads. Again a good wiring diagram for both rigs would make all the difference in the needed up-fit.
I like the seats you picked. Every day. Keep in mind that just the lower drivers set leather w/o the heater,w/o seat foam,and not installed is priced around 250.00usd . The diagrams are cheap.
Best of luck.

 

Thank you XLnAK

How hard would it be to wire up the new seats. Me and electrical, let alone wiring diagrmas, don't get a long too well. Something about electrical gets me intimidated.
How easy would this be for a relative novice.
I might just hire someone to take care of it, if it is too involved

 

How do I do this?

 

the positive and the negative leads from the seat. just take them and conncet them to a batery or a jump box 12v of course and you should be able to move the seat temporarily. if you need to you can take wire and enlongate the leads to reach a battery

 

bubba, I just installed pwr 40/20/40 seats in my 06 XL which had the std bench seat. You will need the wires and plugs from the old seat. For the passenger side, there should be 2 wires. One is a hot and the other a ground. I ran the hot into my fuse panel where the passenger side pwr seat should be and installed a 30amp fuse. Did the same for the Dr side but there were 3 wires there (1 for the seat belt, which I did not hook up). Pretty straight forward. Now you have the heated seats which I am not familiar with. Get a wiring diagram and find out where the heating element hooks up to.

 

In my opinion, its the spaghetti factor that gets to most. Just looking at a diagram of the plate can be intimidating. But, that said, I would rate the job as entry level to a great degree. As others have mentioned, there just isn't that many leads( wires) to need connecting. You should get the stock other side connectors with some lead still intact. Possibly wires all the way up to the dash underside ( collecting those parts yourself would give you a heads up on the install, in your rig).
When looking at a wiring diagram isolate your viewing, to known or recognized pieces( such as connection points), then trace only paths that pertain, forward and back. Similar to reading a road map. Comparing of wiring diagrams of diff. year rigs, becomes more complicated, but yours is of the same general vintage and should be easy to adapt.
Connecting the wires should be done securely though. Wire to wire should be soldered and shrink tubed. Or insulated(plastic covered) crimp connectors (ends or butt connectors) can be used in a pinch. Just be sure to squeeze em real good and test em by pulling the wires somewhat to assure solid contact, then electrical tape joints, to seal from moisture. Most end of wire insulated connections don't need tape being that they are normally away from moisture.
Not to hard, just some what meticulous, if you care to be.
The jumper idea, is to run a positive lead, and a negative lead from a power source ( spare 12volt battery or battery charger) to the connectors coming from the seat, to power the motor for temporary motion. Its a workable way to move the seat back for the time being. A black wire should be negative( or common),but I have no idea if you'll find a black wire going to the connector. It should be done carefully as to not short your temporary leads against a good pin in the connectors(from the new seat) you have. An assistant would prove helpfull while you power the different pins to supply the seat switch, they could move the switch or hold it in the back position, while you tinker with possible lead positions. I don't know positively, but all the motors and heating elements should be fine with you supplying positive or neg. in other than designed polarity temporarily. The motors may run in reverse and the heaters may not heat at all if connected backward but all you want to do is move the seat to a desirable position to get a few other pieces before finishing the job.
Best wishes.

 

I was waiting for you to chime in on this thread...
