I believe G402 is a coupe only location. If you have the FSM it's noted in a couple places. 8A-150-6 mentions coupe only specifically and I didn't see G402 anywhere else in a quick scan of the FSM. Did you find something that specifically mentions G402 and a convertible?
Where did that diagram come from?
8A-203-0 seems to be very different than yours for a 1993

This was from the 1992 gm service manual. I don't have a 93 manual but it should be the same? It mentions which grounds are coupe only and convertible only 402 seems to be generic for both models. This g402 must be somewhere back there as it's the fuel pump and tail light ground.
