1. obd2b-obd1 conversion harness from www.boomslang.us

4. don't bother with the afr gauge unless you want to drop some coin on a wideband
5. don't bother with the turbo timer either unless you plan on boosting right up to the point you park the car and shut it off. the turbo-timer allows you to idle the car for 1-2 min once you park. if you don't drive like a mad-man and are just cruising for a couple min before you park and shut off the car you're ok. i've been running the same turbo for over 5 years and over 75k miles and don't have a turbo timer.
