fyi the "chip it" fuel cut defender is actually a HKS unit. opened mine up to inspect and it says HKS made in japan.
also you splice it on the middle cable out of the 3 cables on the map sensor.
you'll have red and black for power and ground.
yellow and white is spliced into the middle map sensor cable.
I'd also highly suggest getting a Auber EGT gauge to monitor EGT's and set warning alarms. I've set my gauge to cut out the chip and turn an alarm bell on when EGT's reach anything over 500degrees Celsius
