Hi everyone! I'm a newbie here and need a little help. I am using an 04 GTO engine/ harness/ pcm on my BMW M3 LS1 swap. Unfortunately I havent been able to find a specific writeup on using the GTO harness. I found the pinout for an F-body (99 Camaro) and compared it to the GTO, they are very similar. It looks like there are 12 wires that need to be used from an F-body harness. Comparing the pin locations at the PCM on the GTO harness, I found they are in the same locations. The main difference I found was the GTO has a few more ground wires. The comparison is made at the PCM because the GTO doesnt have the same # of connectors on the body side of the harness. The pinout (for the GTO) goes like this:

C1 Connector

#1- Ground
#19- Ign voltage (switched 12v)
#20- Batty voltage (constant 12v)
#24- Ground
#27- Ground
#40- Ground
#57- Batty voltage (constant 12V)
#58- OBDII for DLC connector
#64- Ground
#67- Ground

C2 connector

#1- Ground
#9- Fuel pump (relay trigger)
#10- Tach signal (output to gauge)
#33- Cooling fan (relay trigger)
#40- Ground
#46- Ck eng (ground side of SES circuit)

Does this look like I have accounted for all wires that need to be connected to make the engine start and run? Thanks in advance for the help!

Pm me a fax # and I could send you the print out,or for $25 you can get a ALLDATA account for the year good for one car,and it has all the GTO info you'll need. Good Luck
