ok the ibs is in and i added a dual rule fill pumps to my intakes. boat came with the stock g1 and i added the the giii and used the gi wiring for the ibs. i wired the giii fill line together with gi so any switch independently could fill any of the bags. any of the giii rockers light up the gi switch when pushed therefore opening the valve. not sure if gi has a relay or not. any thoughts would be appreciated, my pics are lost in the archives.
