Heated seat wiring help

accessory or wipers would also work. The simple fixes are always the best!

 

OK so without sounding too needy, can someone tell me a list of electrical wire/conenctions I should need to rewire this to the battery and relag to the cig lighter?

 

Just get fuse taps and find circuits that aren't used a lot to tap into. These heated seats don't draw a lot of power so you should you should be fine. This is how mine have been wired for 2 years with no issues, my moms car also has a kit that I installed and no issues with fuse taps. Your kit has a relay already so don't complicate this anymore.

 

Check your pm...

 

Quick question. I know this is a bit old, but my seat heaters look just like the ones in the original post...they have an inline fuse. If I use an add a circuit do I keep the inline fuse as well or does that fuse go into the add a circuit? I dont want two fuses on the power line do I?

 

I'd remove the fuse from the seat heater and butt splice that connection. Use the add a fuse as the fuse for the heaters. I can't think of any good reason for having two fuses on the same circuit since if something goes wrong it will be more difficult to troubleshoot.

Also consider using a relay on the seat heater power connection. It should be noted in this thread.

 

I believe these come with a relay. So my plan is to run the driver and passenger heaters to the single add a circuit and plug in each in line fuse to the add a circuit. Thoughts?

 

Did the heaters have their own fuse? If so, that answers your question. Don't take a chance of overloading the trucks wiring. I'd fuse at the battery whereas the relay switches on with the ignition.

 

Wont fusing at the the battery keep the power always on? I would think using an open fuse location would be best to allow power when ignition is on

 

Check post #81. I think that will answer your question. The relay in that circuit is only enabled/energized when the ignition key is turned one or two clicks.

 

Took a look. This is from the Clazzio web site:

How hard is the kit to wire?
It's pretty simple, really... There is one ground, and one positive lead for each seat. Simply join the 2 kits together, and run the black to a good solid ground, and run the red to a circuit that turns on and off with the key. A pretty common circuit to tap into is the cigarette lighter. In most vehicles, the amperage is high enough to run both seats on high without blowing a fuse, and they usually turn off with the key.

 

There are lots of ways to wire this up. Some methods carry less risks than others. If it was my vehicle I wouldn't do it that way since you're dependent on whatever else is also drawing current on the tapped circuit. In my opinion a dedicated circuit is the way to go for a seat heater install. Granted it will take a lot more time to wire it up but will significantly lower the risk of something going wrong (as long as you use appropriate wire gauge, connectors/splices, etc.).

 

I don't think it needs to be as complicated as the diagram. Here is the harness and relay. Looks like the switch and the power/ground wires come from relay. I figure I can wire both passenger and driver (+) together and run it to the add a circuit.

 

And relay

 

Ultimately, it's your truck you can do it any way you want...

 

I mentioned there are various ways to do this mod and some are better/safer than others.

Would I use that method on my truck? Not a chance.

 

Im planning an rtmr with one of the fused only circuits to convert the 12V plug to always on. Then I can repurpose the existing lighter socket power lead to source both the switch and relay power. Already appropriately fused, already ignition on, only need to tap the AC panel illumination wire for the LEDs which I plan to do anyway for other additions to the center switch panel. This would eliminate the fuse taps in the cab fuse panel and preserve the kit wiring harness keeping most of the wiring in/around the center console area. Using the bussman for the heater relay would mean discarding and rewiring the entire seat heater harness. This lets me keep things clean and simple which is the intent behind using the rtmr.

 

Seat heaters made it through the winter without any issues. Used them this week and still running strong.

 

Looks right to me. The harness takes care of the relay connections, all you need is power from the battery and ground.

 

A relay is a switch for high current. The switch you press with your finger controls a small current that turns the relay on allowing the relay to supply the much greater current used by the heater. The fuse protects all the wires behind it from shorting to ground. If a short occurs the fuse blows instead of the wire(s) overheating and causing a fire. The red wire is in two pieces because firewall. The red wire from the harness goes through the firewall and connects to either end of the red fuse wire. Other end of the fuse wire goes to the battery +. Battery - is the best ground but it's common to connect to the frame or chassis as long as you ensure bare metal to bare metal contact(no paint)
