can we not waterproof all the electricals and electronics of our vehicles? i'm thinking pwede naman siguro i-seal ng silicone sealant lahat ng harness connectors, all ecu/tcm/bcm boxes then seal also the plugs when they are already plugged in. san kaya pwede pagawa ito, sa casa if still under warranty? kaya ko i-diy pero yun lang nga baka i-void naman nila ang warranty pag nakita nila na ginalaw yung mga boxes.
