Can somebody help me with my heated seat wiring?

[BlackCat914]

Not sure if anyone can help, I pulled some heated seat elements, wiring, and switches out of a 2002 Infiniti QX4. There's a lot of similarities between the two trucks surprisingly, so I thought someone might be able to help.

The wiring out of the element pad has 3 wires. One pink, one brown with a white stripe, and a black wire, seen here.

The wiring out of the switch has 4 wires. One pink, one purple with a white stripe, one solid purple, and one green with a black stripe, seen here.

The switch has two settings, a high and low, and an LED that comes on when the heater is activated. Any insight?
Edit: for those with sigs off, it's a 97 SR5

That's awesome, thanks! But, it's saying the colors from the connector should match the switch wiring, which it doesn't. The switches have different wiring colors than the diagram. Everything else matches.

Can you match the numbers at the switch 1,2,3,4 to the wire colors?

Your best bet is probably going to be this:

Wire #1 - 12V Switched
Wire #2 - Brown/White
Wire #3 - Yellow
Wire #4 - Seems like it's a ground to me based on the QX4 Diagrams.

Wish I could be more help, but I haven't got around to wiring up the seat heaters in my QX4 seats yet.

Actually just figured out how to test which wire is what on the switch.

I've got switches out of a J30 (Different than QX4 in colors, same switch though.)

Here's what I did.

Take your suspected 12V Switched wire, connect it to the + Batt terminal.

Flip your switch on, high or low doesn't matter.

Touch your suspected ground to the - terminal, if the LED indicator on the switch lights up, you've got it right.

Once you figure out which is power and which is ground, leave your power hooked up.

Take out your dome light bulb, rest one end on the ground terminal, flip your switch one way, touch each remaining wire to the opposite end of the bulb, if it lights up, that wire is the high or low wire (whichever way it's switched) and the other wire is the other way.

Took me about 5 minutes and nothing special as far as tools go.

Awesome, great idea! I'll give it a go! The only problem I realized after I posted this last night is that each switch has different color wiring. The pass side is completely different than the drivers.

Mine both have different colors too, but the wire positions in the plug are the same.

Got the switch to lite up in both high and low settings, but no dice on a warm fanny. I still have one leftover wire. If I unplug the element from the switch, the light goes out, even tho the switch remains powered.
Edit: figured it out. Both are working just fine.

Nice! Glad I could help. How are you mounting your switches? That is the main reason I haven't got to it, I have no clue where to put them.

They take a while to warm up. I had an 03 QX4 and it took forever for those MF'ers to warm my booty in the morning. On long trips however it was very nice.

I'm glad to see you got them all wired up. Did you install these in leather seats or cloth?

Thanks again man! Switches are mounted right by the e-brake, they fit perfect and look factory.

I've since flipped them around the right way.

My 12 G37 company car took forever too, but these seem to warm up in about a minute or so. I installed them under my cloth seats.
