Hey Scott,

I've assumed (you don't say) you have a gen2 Solara. Be sure and note whether there are wiring differences between the coupe and hardtop (there are occassionally).
Note, on my Solara site (
http://gadgetjq.com/solara ) in the 'Maintenance' section is a link to 'Toyota Information Services' where you can download the entire service manual for your car along with all technical service bulletins and other information.
Cheers,
John
