I have a eg with obd one engine harness with obd two itr swap i have a obd 2 plug but what colors do i splice together?OBD Two plug red brown ,blue brown,green brown,black yellow.OBD 1 plug blue white,yellow white,blue black yellow

 

What I found does not match with your OBD2 wire colors:

OBD1=OBD2
Blk/Yel=Blk/Yel
Wht/Blu=Wht/Blu
Blu=Wht/Red
Wht/Yel=Wht/Grn

 

just match one wire at a time with each plug. splice the wires that line up with eachother. also u can google pictures of BOTH clips and do it that way...unless u have both clips, then u should just splice one wire at a time
