Seat install

[Green Monster]

I'm wiring the late model Suburban (99-06) power seat (just up, down, front and back.....the recline is manual). The guy I bought the seats from said I just need to run power to the orange wire and ground to the black. But it doesn't work. I tested it and I have power at the wire, so I know there's juice. Any ideas?

Sure you have a good ground.

Switches might be bad.
Best to expose all the wiring and trace where it goes. That way you know and also can check for wires that are chafed/cracked/shorted. Motor will more than likely go to a DPDT switch. Switch will have power and ground connected at two connectors. Depending on which way the switch is thrown will determine direction of the motor. Pics of all would be handy to post.

Thanks, I know the front/back motor works, as I stuck wires in there and hooked it to a battery to move the seat forward and back to install. Think I should lose the plug, and just splice into the wires directly? Also, any idea if I need more than just the orange hooked up to positive? Will post pics as soon as my son is done washing it.

Plugs are there for a reason - to make removal of the seats easier. They are rarely the source of problems, so keep them.
How many wires are there on the plug?

Will look tomorrow afternoon, just got back from dinner and it's dark. Thanks for your help.

Here is the picture, I have big orange and black, then small green, black with white stripe and two blues. Same coming out the other side, but the blues are yellow.

Can’t see the pic since I’m not a member, but you can repost it like this:

If you upload the pics to the media gallery and then click the camera icon while making a post you can drag and drop into a post, everyone can view the pics.

My best guess is that the heavier gauge black and orange wires are ground/power respectively and the four smaller gauge wires are for seat position memory and seat belt reminder sensor. I’d have to look at a schematic to be positive. Seat should function manually without those four smaller wires though.
What I’d do is gain access to the switch contacts and see if they have continuity (or zero ohms if your multi-meter doesn’t have that function) when you operate the switch.

Ok here it goes....

There's no memory, but probably reminder. The other plug, that I cut way back is the airbag.

This was the best link I could find.
https://www.justanswer.com/chevy/1dqiz-wiring-diagram-power-seat.html
About 3/4 of the way down the page is a link to ‘Power seat connectors’. Separate your connector and see if one of those matches what you have. But from what I’ve read (and as I thought) just connect ground/power to the black/orange respectively and seats will work - unless there’s a bad switch.
What’s the back story on these seats - why was the guy selling them and what year ‘burb did they come out of?

Thanks, I'm not sure what year, but they're 99-06 seats. Guy I bought them from has this as his side business, sells a lot of them. I would have no idea how to diagnose a switch issue, I can't even see any switches when I flip it over. But what doesn't make sense is why all of the "extra" wires don't need to be hooked to anything. If each one serves a purpose (forward, reverse, front up, front down, etc) why wouldn't they need to be hooked into power?
