Hi everyone,
Kind of a long post, but bear with me. I'm well outside my comfort zone. George Graves, Greg's///M, and Mo Brighta have all been very helpful thus far, but I'm obviously an idiot because I still need help and feel bad continuing to pester them.
I've bought a pair of power Recaro seats I'm installing in my E30. E30s obviously never had power seats, so I need to run power to each seat. The power also has to be switched with the ignition because the seat has lighted buttons. Recaro suggests a 15A fuse per seat. The wiring coming out of the seat is 14 or 16 gauge, so 15A seems like plenty. This was my thought:
My car has this auxiliary fuse box installed from the factory:
The hot lead is rated at 26A, so my thought was to wire in a relay after this box. I found this image of wiring in a four-pin relay as a reference.
The "hot" pin (30) would be attached to the red wire (constant hot), the switched pin (86) would be attached to the green wire (switched power), I'd ground the ground pin (85), and the current out pin (87) would then run to the seats. That way the seats only get power with the key on and the relay protects the buttons from getting overloaded.
Each seat has a red and brown wire coming out of it. I'd ground each brown to the chassis and attach the red to the wire from the relay.
Does that make sense? Wiring really isn't my strong suit so I'm struggling to conceptualize this. Some guidance would be very helpful.
Thanks,
Mike
