I know this is a dumb question, but how do you get the seat off of a S2000 chassis. Is it the two nuts in the back of the tunnel? Fuel gauge is intermittent and that is the last thing for me to look at.

There should be two 13mm nuts inside your trunk. Take them off, then slide the seat back a bit, until you can unplug the taillight connection, then remove.

Easy!

You got it.... pull the seat backwards (gently) and unplug your tail light connection. Make certain you don't pinch any wires puttin it back together.

I think the 2 bolts holding seat on will be fastened to the seat. They will stick down through the tunnel and have 2 nuts on them. You'll have to get on your back and look upwards above rear of track.
