in my 88 hatch, im running a b16 from a 99 si, odbo. off my coolant temp sensor is two wires, red white and green white, the the green white splices with tho more green white wires, once abou a foot off of the sensor, then they splice back and the green wire connects to my ecu(pr3) at c6. the red white hooks up at c12. anyone familiar with this wiring?

 

my wiring diagram says the following..

C6 = Red/Wht = TW Sensor (coolant sensor).
C12 = Grn/Wht = Ground for multiple sensors (PA, TPS, etc.)

edit: confirmed by service manual to be correct.
