I rarely play Electric (Rhythmic guitarist here so I'm more comfortable with Acoustic) but I have to learn Car Wash by Rose Royce for a performance. There's a tab on here, but it doesn't seem to help much. I'm stuck here.

Any ideas? I tried playing along to the chorus with a F7(#9) but with no avail. Can anyone have a listen to the song and give me ideas? Tips? Or a way to better understand and teach myself the tabs on here?
hey did you mange to get a good tab for this song i have the same problem i have a performance of this song coming up but can't find a tab that sounds right
