Car starts everything else is wired together but missing a few wires

Who has used a 90 harness from dsm?
Defogger wires? dont really need it now, didnt care much just wanted car running(but chicago winter sucks sometimes & might need that later on)
Im also looking for the data transfer wire from the 90 harness. I looked & thought said white wire... I could be wrong... anyone help on this one? where this wire is at? or where could i tap into by ecu directly for this? Im trying to hook this up so i can datalog...
And the tach wire from dsm harness its the white wire with red specs , close to the ecu that has 7 wires to the plug?
thanks..
