EBC will only take about an hour. You need the EBC power wires connected, vacuum line to the new boost solenoid then out the other side back to the standard nipple, solenoid to EBC connection wired in, plug standard solenoid vacuum line, and boost pressure line from the plenum to the EBC if it displays boost.... Fairly straight forward and way easier to set correct boost
Just updated this with some further details to make it a bit easier for you install lol..... To get through the firewall, i drilled a new hole next to where the accelerator cable comes through the firewall and used silastic to seal the hole
