Hello i am having trouble connecting the IAT2 sensor I am using the stock cobra sensor do I need to connect all 4 wires?

[myrodr]

no you only need two I can't remember but I think it is the outer two? try looking up the wire pin for the cobra sensor. Sorry if this don't help if I find the pin I'll post. you can also try looking on this site at eaton swap threads.

Look for the sketch in the Eaton swap thread. Don't reverse the image in your head and hook up the wrong 2 wires like I did. I believe it is pin 3 and 4 if memory serves.....

Ok thanks for the response that's what I did I connected the gray n red to pin 4 n all grey one to pin 3 but just wanted to be sure that I am doing it right

If your using the stock cobra IAT2 sensor which bolts in by the back of the drivers corner of the eaton with two little bolts, you need to use all four wires. Two wires come from the MAF and the other two come from the EGR harness. Be careful to not mix them up.

EGR wires aren't needed. I've hooked it up two different ways with two wires and for whatever reason both worked. Just datalog and you'll know if its right.

Pins 3&4 on the cobra IAT are used for the IAT wiring in the Marauder harness.

Here you go,


From MM (--->)To Cobra

From MAF
MAF P1 Gy/Rd ---> MAP/BAP/IAT2 P4 Gy/Rd Signal Return
MAF P6 Gy ---> MAP/BAP/IAT2P3 DB/LG MAF Signal

From EGR
EGR P2 Bn/Wh---> MAP/BAP/IAT2 P2 Bn/Wh Reference Voltage
EGR P3 LB/Rd ---> MAP/BAP/IAT2P1 Rd/Ye MAP Sensor Signal

Some people have all black wires with their cobra IAT2 pigtail for whatever reason, I say go by the Pin numbers
