I found a 3 bar MAP sensor and harness plug for $60. I'm not sure if anyone knows if this will work or not:

If the one from Full Throttle has the harness plug I'd just assume get it from them. After shipping it will end up being about the same price.
Also, for the wideband input is the ground a necessity to connect to the MAF-T Pro? My FJO wideband has a 1-wire output. I'm not sure how other wideband controller units are configured. I'm planning on ordering mine this coming paycheck.
