You will need to install a weld on bung into your exhaust (either pre or post turbo) and insert the attached thermocouple. It was attached to the upper end of the A pillar in my SMB, and worked fine when I had it removed to install an X-Monitor about two years ago, and as far as I know all parts are included, but I do not have the instructions. If you install it and it doesn't work, I'll refund your money.
