Does anyone know whether 1999 es 300 seats bolt up and use same electrical connections as 97 ES 300???

 

Yes they should. *then again i have never compared the two*

The only discrepancy i would potentially see is if you tried the 00-01 seats in the 97.

For some reason they did a few minor changes in the years, and i wouldn't be surprised if the connectors was one of them.

 

they should fit no problem, i put 01 seats in my 97, so 99 to 97 should definitely work

 

I will give them a try...

 

Did the electrical connectors hook right up? Or were they different from 97 to 01?
