I have an 89 Acoord Sei with well worn and torn leather. I want to replace them with used factory seats but want to ensure they will fit (front and rear). Can I use 1990+ leather seats and can I get power ones and run a 12V feed to them to get them to work??? Thanks for the help.

 

89 and 90 should be about the same, in theory yes you should be able to swap them out with electric ones fairly easy. The only way to know for sure would be to look at some wiring diagrams and compare the two. However, even if it takes some time to get it to work at least you'll have some nice seats while you are working on it!
