hi guys i am working on this project.. I have this this relay board that plugs in the computer so i can turn on and off stuff in my car.. i have a big question tho. THat realy board has 8 channel but each channel only holds 1 amp and under body neons and etc pulls more then that .. so i was wondering if i can use a relay and use the relay board as a switch if yes how do i wire it up? you can email me at shyampatel3@yahoo.com or post something here. thank you

just use the output to trigger a 30 Amp relay, If the output is postive:

Terminal 85 : Output from relay board

Terminal 86 : Ground

Terminal 30 : 12 V Constant (high current)

Terminal 87: Output to neons and such
