Comes with ECU, vacuum line, serial cables, and serial/usb for tuning with a "this decade" laptop. Works perfectly! $625 local, $650 shipped OBO
I finally pulled it off - but I also have an AEM UEGO for sale (model number 30-4110). Comes with original box, wideband sensor, black/silver gauge surround, gauge, wiring, etc - AND also included a wideband extension so that you don't have to modify your car's wiring! $130 shipped.
Buy both and knock $30 off the shipped price ($750 shipped, $720 local)
