Long Roof Posted January 19, 2015 Share Posted January 19, 2015 I am swapping out my manual front seat in my 1956 wagon for a 6-way power seat. Looking at the shop manual, it looks like the power feed was an un-fused wire from the fuse box. Is this how they were wired? Did they have an in-line fuse?Thanks for any comments.Steve Link to comment Share on other sites More sharing options...
JohnD1956 Posted January 19, 2015 Share Posted January 19, 2015 I would put in a fuse regardless if the original was direct wired. Link to comment Share on other sites More sharing options...
buick5563 Posted January 19, 2015 Share Posted January 19, 2015 55's had a seat relay. Not sure if 56 is the same. Link to comment Share on other sites More sharing options...
Long Roof Posted January 19, 2015 Author Share Posted January 19, 2015 Well, there is one 12 or 14 ga red wire coming off the seat harness. When I hook it to to 12 volts and ground the frame, the switch operates all of the positions properly. There are several relays in the operating mechanism. I just wanted to know how the main power feed got to the seat harness and where it originated. I would like to duplicate the circuit if possible.

old-tank Posted January 19, 2015 Share Posted January 19, 2015 (edited) 55's had a seat relay. Not sure if 56 is the same.and a circuit breaker.Both the service manual and body manual show a harness assembly for the power windows and seat, but there are no details. You can hook it up directly to 12v+, but it really should be switched by the ignition, in which case you will need a relay like this (but not at this price ) http://www.ebay.com/itm/NOS-GM-PONTIAC-OLDS-BUICK-CHEVY-54-55-56-57-59-60-61-DELCO-RELAY-WINDOW-AC-/271159108399?pt=Vintage_Car_Truck_Parts_Accessories&hash=item3f2257a32f&vxp=mtrand at least a 40 amp circuit breaker. Both are located behind the drivers side kick panel.Williecheaper: http://www.ebay.com/itm/like/290545873277?lpid=82&chn=ps Edited January 19, 2015 by old-tank (see edit history) Link to comment Share on other sites More sharing options...
Long Roof Posted January 19, 2015 Author Share Posted January 19, 2015 Thanks for the comments and input. It is starting to make sense to me now. In my last post I said there were relays but I meant solenoids in the seat mechanism. Link to comment Share on other sites More sharing options...
