as described above the orange wire which is a constant bat power wire i spliced into from a 4 pin connector that wasn't used taped to the dic harness under the dash. the green wire for the vss i spliced into from the back of the speedo. the tan wire which is a data wire i spliced into where the diagnostic plug is. I did not cut any of these wires but used a crimp on splice connector. it took about 2.5 hours. what took the longest was finding the right green wire on the back of the speedo.
