91ls400own

My project coming along great! Just installed new clean carpet now installing new seats in 91 model. Came out of a 94 model. Problem: the connectors are not same so I need to cut and paste so to speak, connector from 91 onto the 94 seat BUT I have one extra wire on 94 seat. both have the thick W/B and B/W the much thinner Green/gray but the 94 also has a similar thin wire Red/Gray..... the last one is for the Lumbar I am sure as my 91 passenger seat did not have lumbar. QUESTION: I was thinking of splicing the Green and red together and wire to the lonely green coming of the floor connector.
What do you know, can I do that? THANKS ALL OF YOU FOR ALL PREVIOUS HELP!!!

And last but not least, the diagram for the seatbelt tension reducer. The lonely SOLID GREEN wire is in fact for the seatbelt tension reducer. Make sure to NOT confuse it with solid Light-Green wire, which is the main wire for heater circuit.

Ok, now. First of all, you need to specity whether you are talking about a passenger or a drivers seat. They are different and have different sets of wires.

With that being said, you only need to connect two wires to make the seats move in all directions. Those would be the thick White/Black and Blue/White thick wires. W/B is ground and Blue/W is power.

On the passenger seat, the light green wire is heater, solid green is seatbelt tension reducer, Blue/Black is heater switch, LightGreen/Red and Red/Yellow are also for heater, and Red/Green is buckle light.



On the drivers seat, you also have the thick White/Black and Blue/White thick wires. W/B is ground and Blue/W is power.

Then you have red/yellow which is for heater, solid dark green for seatbelt tension reducer, Red/Blue for buckle light, and the rest of the wires are seatbelt warning and memory functions.

Thank you so much for info. The seat was the Passenger side and when I went to connect the seat to floorboard a) connectors were different b) my 91 had 3 wires ground. hot and the third thinner dark Green wire with white or gray circles circa 1# apart
the conector on the seat has 4 wires, same as before but also a thin red/green with the same circles on it. This seems to differ from what you wrote. I do not know what the new (94) The driver seat has same except instead of red/green it has red/blue
and again my 91 seat only has the same 3 as the passenger seat However the floorboard connector on driver side has a 4th salmon colored wired that was apparantly not used on seat. So what do I do with the extra red/blue and or red/ green wires that have no matches on theharness of my91? any ideas?

The passenger seat of a 94 should have 8 wires total, just like I described them above, asuming its heated.
