4th gen seats into my 2nd gen 77 Trans am wiring

Post by johnny46 » Tue Jan 06, 2015 7:34 pm

Hi all

Ok I bought some 4th gen seats of the Brydens out of a 4th gen that have fitted in a treat into my 77 Trans am, they look great and they have electrics for seat adjustment, now I have put in the correct amount of cables from each seat to the boot where I will mount a fuse box for the seat.

Now I need a diagram or wiring plan of what fuses I should us e and how it should be wired etc

As you can tell I don't have a great knowledge of electrics but would like to have a go at wiring it up don't worry the cars going to robin in February to check everything but would like to get it somewhere near if ya get me

Cheers guys

Johnny

First of all,

I need to know what function the seats have - not familiar with what they do. Do they have heaters and electric adjustment backwards and forwards, up and down, electric seat back?? Once we establish this, a wiring diagram can be made. It might be as simple as feeding the 12v to a common supply cable in the seat harness - did you get the wiring and switches with the seats?

Then I would need to know the wire sizes as the fuses will be sized to protect the wiring.

Come back to me dude and we can get it nailed

Sounds like a nice conversion - those original seats are disappointing. Do you have any photos of how they look in the car?

Re: 4th gen seats into my 2nd gen 77 Trans am wiring

Ok folks try and stay with me and my incorrect wording :)

As far as I can tell there electrical for lumber support as its manual levers to send seat forward and back towards back seats along the rails and also manual lever to pitch the back of the seat forward and back in a more lay down position, so I'm guessing the buttons you see in the picture have something to do with lumber support?

The drivers seat houses the electric pump and has a nylon pipe from that seat to the passenger seat for the air to cross,
The drivers seat has a female plug with 5 wires 2 fat and 3 thin

The passenger seat has another female plug with 4 wires 2 fat and 2 thin

I do not know if the seats are heated

I have ran the Same amount of wires from the seats to the boot, fat ones I have matched in size and the thin ones I have matched in size and the amp wire I used for these is 8 amp I cannot remember what the amp is for the fatter wire but it's around 3 times the size of the thin wire

I have run a big cable to the boot from the battery that has its own fuse, and I have this fuse junction box if this would work to go in the boot to accept the main cable from battery and for the other small wires

Sorry about my wording it's not exactly a auto electrician speaking lol

I have attached some pics of all the above points


Hope you can help

Re: 4th gen seats into my 2nd gen 77 Trans am wiring

Post by bhm1712 » Thu Jan 08, 2015 7:04 pm

Right I've had chance to look through my wiring diagrams for 4th gens and I have managed to find out the following:

Orange = 12v +
black = 12v -

The grey, white and grey/black wires are for cross seat connections and deal with the lumbar inflate and deflate switches.

Basically you don't need all the wires going back to the trunk. You only need a positive and negative supply to the drivers seat.

So:

12V+ from fuse to the Orange on the drivers seat plug.
12V - from chassis or fuse box ground to the drivers seat plug.

Then join Orange on drivers seat to orange on passenger seat, black on drivers seat to black on passenger seat. Then the other 3 remaining wires are the same - joined colour to colour from drivers to passenger seat.

As for wire gauge and supply fuse you would need to tell me what the exact outside diameter of the orange cable core is for me to correctly size the fuse, however if you are 100% sure the mm2 of the cable you use is a match for the orange original wire on the seats you will need to use a 30 amp fuse.

Now that makes the job a lot easier?!!

Like this

This ain't a wing diagram as such it's a layout of where wires need to go if you will.
