this is an 8 way seat dont really need anything but forward backward up down and inclne recline seat back, It is a memory seat It is just the power track I put my seat on the track no issue. there are no switches to operate but they are in the way still need to know how to wire to operate to move the track to bolt in place
Expert:  Jerry Newton replied 1 year ago.

OK, I see.

Are you good with a schematic? I am attaching one here that illustrates how these circuits work. It's a lot of wiring with the memory seats, but if you can read a schematic, the information is there. Let me know if you need anything deciphered.

What wires do I need to get her going I know orange is hot and black is ground That is how my truck is wired my pigtail (I cant USe) only had 4 wires orange black blue and white
Expert:  Jerry Newton replied 1 year ago.

Oof. Sorry, I attached the wrong schematic. Let's try this one instead.

Look at the lower left corner of this schematic. You can see the black and red wires going to the horizontal motor. Forward and reverse is just a matter of reversing polarity. Use jumper wires, and supply power to one and ground to the other. If it goes the wrong way, reverse your wires and move it where you need it.

You'll be wiring this up at some point, yes?

Expert:  Jerry Newton replied 1 year ago.

The issue here is the memory seats. You need the memory seat module to make this work correctly.

Expert:  Jerry Newton replied 1 year ago.

And you're still going to have issues with your switches, assuming you have a new body style 2007 truck.... the switches are going to be different, so will require some ingenuity to get this working.

dont need memory to work it is just me so i jst need to power it old body style
Customer: replied 1 year ago.
memory seat module is in place I assume it is the black box attached on top of the rack
Expert:  Jerry Newton replied 1 year ago.

I understand.

The first schematic shows you how the switches connect to the MSM (yes, that's it attached to the bottom of the seat cushion). The second schematic shows you how the power is controlled.

Expert:  Jerry Newton replied 1 year ago.

You have the proper switch with the replacement seat, yes?

Customer: replied 1 year ago.
Not yet but its coming 2 switches Im just trying to work ahead, still though which ones from the seat harness should I use do i need to concern myself with all of the little wires
Expert:  Jerry Newton replied 1 year ago.

If the switch is there, all of the wiring should be connected. I guess I'm a little confused, you got a complete seat, with MSM and with the switch still attached to it, right? Because if you have all of that, you would only need to supply power and ground to the seat, via orange wire (B+) and black wire (ground).

Expert:  Jerry Newton replied 1 year ago.

I'm not sure what other wires you have hanging out of that seat. Airbag wires will have a yellow connector. Give me some wire colors for the other wires you don't know what to do with.

Also be advised that I need to leave my desk in just a few minutes, and won't be back until tomorrow. I will follow up with you, though, I'm not going to abandon you.

no switch but can jumper i just got the seat base it was all wired but no switches. came from LKQ It can I take a picture and email it or text it to you
Expert:  Jerry Newton replied 1 year ago.

Sure, take a picture, that might help. I think you definitely just want to get the proper switch for it and use that.

Got seat moving by jumper wires do I need a seat bottom with switch bezel or can I use a manual seat bottom and add the bezel
Expert:  Jerry Newton replied 1 year ago.

That's a good question, I don't "know" that the cavity is there to install a switch in a manual seat cushion. I suspect not, but you'd be able to just feel in that area through the seat cover to see if there is a cavity underneath.

Would be cheaper/easier to source a seat cushion with the switch attached, I'd think.

Which motor runs the seat back reclime
Expert:  Jerry Newton replied 1 year ago.

light green and light blue wires go to the recline motor. Sorry, that got cut off of the drawing I sent you.

Customer: replied 1 year ago.
