Guys, Quick question. I know you guys are not recommending installing the fuel wires or bcm anymore but the JB4 I bought has both. I have referred to a protecons install post and the wiring color for the BCM is correct but I do not have Purple or green fuel wires for the JB4 ECU. I have brown and black. I read in a previous post terry said they ran out of Purple and green wire and used brown and black instead.

As i understand
Purple Female - Black plug #45
Purple Male - Yellow/White from Black plug #45

Green Female - Grey plug #44
Green Male - Yellow/White from Grey plug #44.

I have coming out the JB4, my Green and black for Canbus, The blue going to the BCM, then I have 2 Brown Male/Female and 2 Black Male/Female. Which ones go to the black plug and which one go to the grey plug?

Thanks again
Chris
